Accelerated polishing tester used for testing dynamic frictional force of pavement materials

The utility model relates to an accelerated polishing tester used for testing dynamic frictional force of pavement materials. The accelerated polishing tester comprises a workbench, a counter weight, a to-be-tested test piece, a test mould for fixing the test piece, a polished test piece, a fixed module, a fastening module and an electric lifting module, the electric lifting module comprises a lifting platform, the counter weight and an upper slide table, the counter weight is fixedly connected with the upper portion of the lifting platform, the upper slide table is fixedly connected with the lower portion of the lifting platform, a rigid plate, an elastic element and the fixed module are connected to the lower portion of the upper slide table sequentially, a plurality of spray heads capable of spraying water are arranged above the circumferential side of the fastening module, a heating system and a refrigerating system are arranged below the fastening module, and the fastening module can reciprocate linearly relative to the fixed module by being driven by a motor. The accelerated polishing tester used for testing dynamic frictional force of the pavement materials is capable of accurately simulating and testing abrasion of roads when vehicles are at high and low temperatures, in different wet and slippery degrees, at different speeds and in different load conditions.
