SYSTEM FOR DETERMINING THE SOFTENING POINT OF BITUMEN
Field of the Invention
[0001] The present study relates generally to the field of material testing and analysis, and more specifically to a system for determining the softening point of bituminous materials.
Background
[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] In the field of material science, particularly in the characterization of bituminous materials, the determination of the softening point is crucial. The softening point, indicative of the temperature at which bitumen transitions from a semi-solid to a viscous liquid, is vital in assessing the material's suitability for various applications, such as in road construction, roofing, and waterproofing. Traditional methods for determining the parameter have relied on manual techniques, which, while effective to a degree, exhibit several drawbacks.
[0004] Historically, the prior art ring-and-ball method has been extensively utilized. In the approach, bitumen is heated at a controlled rate, and the softening point is noted when the bitumen layer deforms under the weight of a steel ball. Despite the widespread use, the method suffers from a lack of precision, primarily due to the manual observation required to determine the exact moment of softening. Human error in the observation leads to inconsistencies in results, rendering the method less reliable for applications demanding high precision.
[0005] Further, the traditional setup lacks advanced temperature control, typically relying on a manual heat source such as a Bunsen burner. The rudimentary form of heating introduces fluctuations and uneven heat distribution, which directly impacts the accuracy of the softening point measurement. Inaccurate temperature control often results in a non-uniform heating rate, which is a significant variable affecting the softening point of bitumen.
[0006] Moreover, manual methods require constant supervision and intervention, making the process labour-intensive and time-consuming. Such requirements increase the likelihood of operator fatigue, further exacerbating the risk of human error. The manual nature of said methods also limits the throughput of testing, as each sample requires individual attention and handling.
[0007] Additionally, said method and the variants lack a sophisticated means for capturing and recording data. The reliance on visual cues and manual recording of temperatures at the moment of softening introduces an element of subjectivity. Such methods lack the precision of digital recording instruments, which can capture minute changes in temperature with high accuracy.
[0008] In light of said limitations, the industry has recognized a need for an automated, precise, and reliable system for determining the softening point of bitumen. There exists a need to address the inconsistencies and inaccuracies inherent in manual methods. Said elimination of inconsistencies and inaccuracies are not only necessary for improving the quality of bitumen testing but are also vital in keeping pace with the increasing demands for precision in material characterization in various industrial applications. Therefore, the development of an advanced system for determining the softening point of bitumen can represent a step forward in the field of material science, addressing the drawbacks and limitations of existing methods.
Summary
[0009] The present study relates generally to the field of material testing and analysis, and more specifically to a system for determining the softening point of bituminous materials.
[00010] The following presents a simplified summary of various aspects of this disclosure in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements nor delineate the scope of such aspects. Its purpose is to present some concepts of this disclosure in a simplified form as a prelude to the more detailed description that is presented later.
[00011] The following paragraphs provide additional support for the claims of the subject application.
[00012] The disclosed subject pertains to a sophisticated system designed for the determination of the softening point of bitumen, a parameter in assessing the quality of bituminous materials for various industrial applications. Central to the system is a water bath unit, capable of being filled with distilled water. Said water bath unit is equipped with a temperature control device, diligently maintaining the water temperature within a specified range of 4 °C to 8 °C. The feature ensures optimal conditions for the initial placement of bitumen-filled rings, which are configured for stability within the aforementioned temperature range.
[00013] Integral to the system is a cooling module, adeptly designed for cooling steel balls to a temperature range from about 3 °C to about 6 °C. The precision in cooling is achieved through the integration of said mechanism with a sensor system, enabling accurate attainment of the desired temperature range. A delivery module is thoughtfully configured for the precise positioning of said cooled steel balls atop the bitumen-filled rings within the water bath unit.
[00014] Further enhancing the system's capabilities is a beaker unit, tailored to accommodate the water bath unit containing the bitumen-filled rings and steel balls. The beaker unit, filled with distilled water, is connected to an integrated heating device. Said heating mechanism, in conjunction with a feedback control system, is meticulously arranged to uniformly heat the beaker unit. The feedback control system ensures a consistent temperature rise until the bitumen softens, thus facilitating uniformity across different experiments.
[00015] A temperature recording module is functionally connected to the beaker unit. The system is equipped with strategically placed sensors within the beaker unit, tasked with accurately capturing the temperature at which each steel ball touches the bottom of the beaker unit. The culmination of the process is overseen by a processing unit. Said unit is operationally linked with the temperature recording module and is arranged for calculating the softening point of the bitumen as the average of the recorded temperatures. The processing unit represents a pivotal component in the system, ensuring accuracy and repeatability in the determination of the bitumen's softening point.
[00016] Thus, the system, as claimed, embodies a confluence of precision-engineered components, each playing a vital role in enhancing the accuracy, efficiency, and reliability of determining the softening point of bitumen. The system stands as a testament to the advancements in material testing technologies, offering a significant improvement over traditional method.
[00017] In the technical field of material testing, particularly concerning bituminous materials, an advanced method has been developed for determining the softening point of bitumen. The method represents a significant improvement over traditional techniques, offering enhanced precision and reliability. The process begins with the filling of a water bath with boiled distilled water. Said water is meticulously maintained at a temperature within the range of 4 °C to 8 °C. The precise temperature control is significant in preparing the system for the subsequent steps.
[00018] Once the water bath reaches the desired temperature range, bitumen-filled rings are placed into said bath. Said rings are specially prepared by filling standardized ring molds with bitumen and allowing them to solidify at room temperature prior to their use in the test. The preparation ensures uniformity in the test samples, a crucial factor for accurate measurement.
[00019] Subsequent to the placement of the bitumen-filled rings, steel balls are cooled to a specific temperature range of 3 °C to 6 °C. The cooling is achieved by placing said steel balls in a refrigeration unit that is set to maintain the precise temperature range for a predetermined period. The careful control of the temperature of said steel balls is essential for the consistency of the test results.
[00020] Following the cooling process, said steel balls are positioned on top of the bitumen-filled rings. The positioning of the cooled steel balls is performed using a specialized tool, ensuring their accurate and consistent placement across multiple tests. Said positioning step is critical in maintaining the uniformity of the testing procedure.
[00021] After the positioning of the steel balls, the setup, comprising the bitumen-filled rings and the steel balls, is submerged in a beaker unit containing distilled water. Uniform heating of the beaker unit with distilled water is then undertaken until the bitumen softens. The heating is carefully controlled to ensure a consistent rise in temperature, a key aspect of the method.
[00022] As the bitumen softens, the temperature at which each steel ball touches the bottom of the beaker unit is recorded. The recording step employs a temperature recording module, which includes either a thermometer or a temperature sensor. Such sensors are crucial for accurately monitoring and maintaining the temperature of the water bath within the specified range.
[00023] Finally, the softening point of the bitumen is calculated as the average of the recorded temperatures. The calculation is a crucial component of the method, providing a reliable measure of the bitumen's softening point. The method, through the various steps and the employment of precise tools and equipment, offers a systematic and reliable approach for determining the softening point of bitumen, essential for quality control in industries utilizing bituminous materials.

The integration of precise temperature control, efficient delivery module, uniform heating mechanisms, and advanced data processing capabilities in the system addresses the shortcomings of prior art and sets a new standard for accuracy and reliability in bituminous material testing.

[00052] Referring to one or more preceding embodiments, the disclosed subject encompasses the integrated system 100 for accurately measuring the temperature at which bitumen transitions from a harder to a softer state. The measurement is achieved through an arrangement and methodical use of a water bath, temperature control device, bitumen-filled rings, steel balls, a beaker unit, and temperature recording module.

The system is particularly suited for laboratory settings where precision, repeatability, and accuracy are crucial in determining the material properties of bitumen and similar substances.
[00053] Proposed method 200 for determining the softening point of bitumen encompasses a series of meticulously designed steps, each contributing to the accuracy and reliability of the measurement process. The method begins with the preparation of a water bath unit. Referring to a pictorial depiction put forth in FIG. 2, representing a flow diagram of the method 200 that can comprise steps of, yet not restricted to, (at step 202) filling a water bath with boiled distilled water, (at step 204) placing bitumen-filled rings into the said water bath, (at step 206) cooling steel balls, (at step 208) positioning the cooled steel balls, (at step 210) submerging the setup of bitumen-filled rings and steel balls, (at step 212) uniformly heating the beaker unit with distilled water, (at step 214) recording the temperature at which each steel ball touches the bottom of the beaker unit and (at step 216) calculating the softening point of the bitumen. Said steps of the method 200 can be performed or executed, collectively or selectively, randomly or sequentially or in a combination thereof, in accordance with the embodiments of current disclosure.
[00054] In an embodiment, the water bath is filled with boiled distilled water, which is then maintained at a temperature range of 4 °C to 8 °C. The precision in maintaining the temperature range is crucial in setting the baseline for the subsequent steps of the method. A thermometer or a temperature sensor is employed to monitor and maintain the temperature within the specified range, ensuring consistent conditions for the placement of bitumen-filled rings.
[00055] In an embodiment, for the bitumen-filled rings, standardized ring molds are utilized. Said molds are filled with bitumen and allowed to solidify at room temperature before use. Such preparation ensures that the rings are consistent in size and bitumen content, a factor that is essential for the accuracy of the test.
[00056] In an embodiment, the method includes cooling steel balls to a temperature range of 3 °C to 6 °C. Said cooling is achieved by placing said steel balls in a refrigeration unit, which is set to maintain the desired temperature range for a predetermined period. The precise cooling of said steel balls is essential, as they play a key role in the determination of the bitumen's softening point.
[00057] Once cooled, said steel balls are positioned on top of the bitumen-filled rings. For said step, a positioning tool is employed to accurately place the cooled steel balls, ensuring consistent placement across multiple tests. The use of such a tool eliminates variability in ball placement, which could otherwise affect the test results. After positioning the steel balls, the setup of bitumen-filled rings and steel balls is submerged in a beaker unit containing distilled water. Said step sets the stage for the uniform heating process, which is central to the determination of the softening point.
[00058] In an embodiment, the beaker unit containing the setup, is uniformly heated. The heating is continued until the bitumen softens. The uniformity of the heating process is ensured by the use of an integrated heating device, which is calibrated for even heat distribution across the beaker unit. Said aspect of the method ensures that the softening of the bitumen occurs consistently and is not influenced by temperature gradients within the beaker unit.
[00059] As the bitumen softens, each steel ball eventually touches the bottom of the beaker unit. The temperature at which Said event occurs for each ball is recorded. Said recording is done using sensors strategically placed within the beaker unit. Said sensors are crucial for capturing the exact moment the steel balls touch the bottom, thereby determining the precise temperature at which the bitumen softens.
[00060] In an embodiment, the softening point of the bitumen is calculated as the average of the recorded temperatures. The calculation is performed by a processing unit that is linked with the temperature recording module. The processing unit is designed to handle data from multiple tests, ensuring that the average temperature calculated is accurate and representative of the bitumen's softening point. For example, the method in operation can include a scenario where multiple tests are conducted to determine the average softening point of a particular batch of bitumen. In each test, the steps described above are followed meticulously.
[00061] Variations in the method 200 can include adjustments to the temperature ranges, the use of different types of bitumen, or modifications to the heating rate, all of which can be accommodated within the scope of the method. Referring to one or more preceding embodiments, the method 200 described herein represents an approach to determining the softening point of bitumen. By incorporating precise temperature control, standardized preparation of test materials, accurate positioning tools, uniform heating mechanisms, and advanced temperature recording and processing, the method addresses the limitations of traditional testing methods and sets a new standard in the field of bituminous material testing.
[00062] FIG. 3 represents prepared setup for the determination of the softening point of bitumen. The setup is housed within a controlled environment, likely to ensure consistent test conditions. The beaker placed on an electric coil, which serves as the heating element. Within the beaker placed a ring and ball apparatus, to measure the softening point of the bitumen. A PT100 sensor is a type of resistance temperature detector known for the precision in temperature measurement. The laser can be used for precise targeting or measurement within the setup. LDR sensors (Light-Dependent Resistors) change resistance with the light level and are typically used to detect light or shadow changes. Said sensors can detect the bitumen's softening point when the ball drops and interrupts a light beam. A mechanical stirrer ensures uniform temperature distribution within the liquid in the beaker. The CPU fan suggests an active cooling mechanism, to control the temperature or to cool down the system after the test is completed.
[00063] FIG. 4 represents the development of a mobile application interface. A dashboard shown controls the determination of the softening point of bitumen. The dashboard features "Start Test," "History," and "Report." Said buttons are intended for user interaction, where "Start Test" initiates the testing process, "History" allows a user to view past test data, and "Report" enables the user to generate and view reports from conducted tests.
[00064] FIG. 5 represents the components of the ring and ball apparatus, which include two metallic rings with attached ball guides, and two steel balls. Said parts are used in testing the softening point of bitumen. The steel balls, which sit below the rings, are used to apply weight to the bitumen samples during the test to determine the temperature at which the bitumen softens enough to allow the balls to pass through the rings.
[00065] FIG. 6 illustrates the assembly setup for determining the softening point of bitumen, featuring a transparent beaker filled water for a water bath. Inside the beaker, two metallic ring and ball apparatuses are mounted on a stand, ready for testing. The rings are designed to hold bitumen samples, and the balls are positioned to fall through the rings when the bitumen softens at the appropriate temperature. The assembly's purpose is to precisely measure the temperature at which the bitumen transitions to a softer state, a critical parameter in material quality assessment.
[00066] FIG. 7 illustrates the assembly of apparatus after completion of test. A borosilicate glass beaker, filled with water and containing a ring and ball apparatus post-testing. Two steel balls have descended to the bottom of the beaker, indicating the completion of the softening point test for bitumen. Said completion suggests that the bitumen within the rings has softened sufficiently to allow the balls to pass through, marking the endpoint of the test.
[00067] FIG. 8 shows a segment of a mobile application interface, detailing notifications for the completion of various activities in the testing process for the softening point of bitumen. The interface includes checkmarks indicating completed steps of boiling the mold, preparing the base of the ring, and keeping the mold in air for 30 minutes.

[00068] FIG. 9 shows temperature t1 highlighted when ball 1 touch the bottom base plate. The temperature readings during a bitumen softening point test, focussed on the highlighted entry at sequence number 148, where the temperature, labeled T1, reads 50.93°C. At said temperature, Ball 1 has touched the bottom base plate, marking the softening point of the bitumen sample under test. The list implies real-time tracking and recording of temperatures.
[00069] FIG. 10 shows temperature t2 highlighted when ball 2 touch the bottom base plate. Said FIG. 10 emphasized that at the highlighted temperature of 52.19°C, ball 2 has reached the bottom base plate, which is a critical observation in the determination of the softening point of bitumen. The highlighted reading suggests that the bitumen softened to the point where the second ball makes contact with the base. The application can alert the user when the bitumen softens to the point where the second ball makes contact with the base, marking a key data point for analysis.
[00070] Traditional ring and ball apparatus can be used to determine the softening point of bitumen. The ring and ball apparatus required significant human involvement to maintain specific environmental conditions and to manually record data, impacting the precision and efficiency of the test results. The introduction of said system 100, implemented as smart ring and ball apparatus, can eliminate human intervention through IoT (Internet of Things) technology. The apparatus automatically maintains and logs essential parameters such as time, temperature, and the rate of heating, ensuring compliance with the reference standard. Key steps in the process have been automated.
[00071] The system comprises water bath unit that automatically maintains the temperature at 5?. The process of heating and cooling the bitumen sample, and maintaining the temperature of the water bath unit, can be fully automated. Sensors in the water bath unit regulate the temperature, with notifications sent through a mobile app. The system uses multiple sensors, including a laser, LDR, relay, and a PT100 temperature sensor, managed by an ESP32 microcontroller. The setup ensures precise control of the heating rate, enhancing the accuracy of the test.
[00072] The system automates the process of reading and recording the final temperature at which the bitumen softens. The mobile app plays a crucial role here, continuously monitoring the temperature at 12-second intervals and facilitating the generation of test reports. The mobile application, integral to the system, provides a user-friendly interface, real-time data monitoring, and the capability to generate instant test reports in the desired format. The use of IoT technology in said smart ring and ball apparatus or system 100 promises to increase the accuracy and reliability of the test results, making the process more efficient and less prone to human error.
[00073] Example embodiments herein have been described above with reference to block diagrams and flowchart illustrations of methods and apparatuses. It will be understood that each block of the block diagrams and flowchart illustrations, and combinations of blocks in the block diagrams and flowchart illustrations, respectively, can be implemented by various means including hardware, software, firmware, and a combination thereof. For example, in one embodiment, each block of the block diagrams and flowchart illustrations, and combinations of blocks in the block diagrams and flowchart illustrations can be implemented by computer program instructions. These computer program instructions may be loaded onto a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions which execute on the computer or other programmable data processing apparatus create means for implementing the functions specified in the flowchart block or blocks.
[00074] In an exemplary embodiment, procedure for determining the softening point of bitumen begins with the initial preparation of the bitumen sample. This involves heating the sample to a temperature range between 75-100°C, ensuring it becomes completely liquid. To facilitate an easy and non-sticky transfer of the bitumen into the testing rings, a mixture of glycerine and dextrin is prepared, which can be used to coat a metal or glass plate, creating a non-adhesive surface. Once the plate is prepared, the liquefied bitumen is carefully poured into the rings, slightly overfilling them to ensure a complete fill. After pouring, the bitumen-filled rings are left to cool at room temperature for a minimum of 30 minutes, allowing the bitumen to settle and solidify to the required consistency. Simultaneously, steel ball can be cooled in a separate water bath that can be maintained at a temperature of around 5°C for 15 minutes.
[00075] The beaker unit (which can receive cold bitumen-filled rings and cold steel ball) can be filled with distilled water, wherein the beaker unit can be subjected to a carefully controlled heating process. The water in the beaker is heated at a uniform rate of 5 ± 0.5°C per minute. It's essential to continuously stir the water to ensure even heat distribution throughout the beaker. As the temperature in the beaker rises, the bitumen in the rings begins to soften. The temperature at which each steel ball sinks through the softening bitumen and touches the bottom plate of the beaker can be recorded. The recorded temperature is identified as the softening point for that particular bitumen sample. The process is repeated for multiple samples to ensure consistency and reliability in the results. Finally, the determination of the softening point of the bitumen is concluded by calculating the average of these recorded softening point temperatures.

SYSTEM FOR DETERMINING THE SOFTENING POINT OF BITUMEN
Abstract
The study relates to a system for accurately determining the softening point of bitumen. The system comprises a water bath unit for maintaining water temperature. A series of bitumen-filled rings are placed within the water bath. Further, a cooling module effectively cools steel balls. The entire setup, including the rings and steel balls, is submerged in a beaker unit filled with distilled water. The beaker unit integrates a heating mechanism with a feedback control system for uniform heating. Additionally, a temperature recording module meticulously records the temperature at which each steel ball descends to the bottom of the beaker unit. A processing unit calculates the bitumen's softening point by averaging said recorded temperatures.
