Description

Technical Field

[0001] The utility model relates to the technical field of pavement material testing, in particular to a pavement material strength meter. Background Art

[0002] The pavement material strength meter is an instrument used to test the strength indicators of high-grade highway subgrade and pavement materials. It can conduct tests such as compressive strength, flexural strength, splitting, and Marshall stability on pavement materials such as asphalt mixtures. When testing with the existing pavement material strength meter, the operator places the test block of the pavement material on the pressure plate and starts the strength tester so that the pressure block and the pressure plate load the test block at the same time. When the test block breaks, the pressure sensor promptly records the maximum load at the time of destruction, which is the maximum compressive strength of the test block. When the pressure block squeezes the pavement material on the pressure plate, the pavement material is crushed. The crushed pavement material will not only fall on the test plate, but will also adhere to its pressure block and pressure plate. After each test of a material is completed, the staff needs to clean up the waste and materials on its pressure block and pressure plate, making the staff's work more cumbersome.
