Aiming at the problem of interlayer slip damage of asphalt concrete pavement, a new type of pavement shear tester was developed for the simulation experiment of interlayer slip. The shear resistance of different materials and structures was evaluated. Introduced the instrument design principle, the composition of the structure and the use of methods. The test results show that the reliability of the test performance is good, the test method is simple and effective.
