The Research on Dynamic Friction Tester of Pavement
As to the pavement test, with the slip-based control method, a new pavement mobile type of measuring device was designed to obtain the continuous friction coefficient parameters in this paper. The operation principles and the concrete completion methods of slip ratio control were introduced in detail. 89C52 was adopted as the center chip to achieve the system design of hardware and software. After the pavement tests, the prototype is of high reliability, low cost, and simple operation, meanwhile, meets the requirements of pavement skid resistance.
