In order to more accurately evaluate the crack resistance of semi-rigid base asphalt pavement, the cracking mechanism of asphalt pavement is systematically analyzed, and the functional design of the anti-cracking test system is designed based on this. The specific structural requirements are clarified, and its frame and details are carried out. Detailed design, based on the bottom stress sensitivity analysis to determine the test control mode and parameter range, based on the instrument's working principle and inspection indicators, the temperature control system, transverse stretching system, and vertical shearing system are designed and developed to match the instrument Computer-aided analysis software and test. The test system provides equipment support for theorem evaluation of the anti-cracking performance of semi-rigid asphalt pavement.
