Description

Technical Field

[0001] This utility model relates to the technical field of road engineering quality testing, and in particular to a boiling test instrument for compatibility of asphalt slurry mixtures. Background Technology

[0002] Slurry seal mixtures are an important material in highway and municipal road construction, and their compatibility directly affects the road's durability, water damage resistance, and service life. In road engineering quality inspection, the boiling test is used to evaluate the compatibility of slurry mixtures to determine their integrity and coating performance in a high-temperature water environment. This test method is of great significance for judging the durability and bonding performance of slurry mixtures.

[0003] Existing boiling tests for the compatibility of slurry mixtures mostly rely on simple heating containers and lack specialized testing equipment, which mainly presents the following problems:

[0004] Inaccurate temperature control: Existing methods typically use traditional water baths or simple heating equipment to heat the sample, which cannot achieve precise temperature control, resulting in large fluctuations in water temperature during the test and affecting the reliability of the test results.

[0005] Unstable specimen support structure: The specimen is usually placed directly in the test container, and the heating method is uneven. It is easy to affect the determination of integrity rate and coating rate due to water flow disturbance or specimen position displacement.

[0006] The testing process is difficult to standardize: the operation steps of existing testing methods are difficult to ensure consistency, and different experimental personnel may produce large subjective errors when performing the test, resulting in poor repeatability of test data.

[0007] Low testing efficiency: Traditional testing methods usually require manual adjustment of heating equipment and lack effective sample hoisting and support structures, resulting in long testing cycles and making it difficult to meet the needs of engineering projects for rapid testing.

[0008] Therefore, there is an urgent need for a slurry mixture compatibility boiling tester that can accurately control the heating temperature, stably support the sample, and improve the test efficiency, so as to enhance the scientificity and reliability of compatibility testing.
