Description

technical field [0001] The invention belongs to the field of material testing, and in particular relates to a device and method for testing the performance of pavement materials. Background technique [0002] Drainage asphalt pavement is an open-graded asphalt mixture with a skeleton-void structure formed according to the principle of embedded extrusion. It has good drainage, noise reduction and anti-skid functions, and can reduce water mist and water drift in rainy days, and reduce road surface damage after rain. Reflective, improve the excellent performance of driving sight distance, and increase the safety and comfort of driving in rainy days. [0003] In view of the skeleton-void structure of the drainage asphalt pavement, the problems of pavement wear and asphalt mixture particles scattering are prone to occur under the load of the vehicle, and pavement potholes occur, which affect the durability of the asphalt pavement and driving comfort. The scattering loss of drain...
