[0002] Asphalt ductility testing device is a common highway engineering inspection item. By testing the ductility of asphalt, its flow properties under different temperatures and stresses can be accurately evaluated, thereby judging its quality and applicability, which helps to rationally select and use asphalt materials.
[0003] When testing the ductility of asphalt, workers are required to pour liquid asphalt into the mold, and use a scraper to scrape the asphalt in the mold after the mold solidifies. The scraping operation needs to be done manually, which is easily affected by individual subjective factors such as strength, speed, scraping angle, etc., which may lead to deviations in test results and reduce the repeatability and reliability of the test. In addition, manual scraping requires a lot of time and manpower, especially in large-scale testing, which will affect work efficiency and increase testing costs and cycles.

[0022] The specific working principle of the utility model is as follows:
[0023] When the highway engineering inspection equipment proposed by the utility model is used, the staff first removes the asphalt mold 2 from the tensile monitoring device 1, pours liquid asphalt into the asphalt mold 2, and installs the asphalt mold 2 on the tensile monitoring device 1 after the asphalt is solidified. When the asphalt mold 2 is installed on the tensile monitoring device 1, the two scrapers 42 are just facing the middle position of the asphalt mold 2. When the asphalt mold 2 is leveled, the staff starts the motor 51. When the motor 51 is running, it can drive the threaded rod 52 to rotate. Since the threaded rod 52 is provided with two threaded parts with the same length and opposite thread directions, the two moving blocks 54 are respectively placed on the two threaded parts. Therefore, under the limiting action of the guide rod 53, the threaded rod 52 can drive the two moving blocks 54 to move away from each other when it rotates, which makes the two mounting blocks 41 move away from each other. During the process of the two mounting blocks 41 moving away from each other, the two scrapers 42 can level the excess asphalt from the middle of the asphalt mold 2. The leveling operation is performed automatically without manual intervention.
