Asphalt rotary screen abrasion tester is a test instrument used to simulate the abrasion situation of asphalt pavement generated by vehicle driving in the actual use process. In the field of road engineering, through the test of this instrument, the wear resistance of asphalt mixture can be evaluated, which is of great significance for selecting the appropriate asphalt mixture formula and ensuring the durability and service life of the pavement. For example, in the construction of roads with large traffic flow and high vehicle speed such as expressways, the requirement for the wear resistance of asphalt mixture is relatively high. Through the test of asphalt rotary screen abrasion tester, asphalt mixtures with good wear resistance can be screened out, thereby reducing pavement diseases caused by abrasion, such as loose surface and potholes. The instrument mainly simulates the abrasion effect of wheels on the pavement through rotary motion. The asphalt mixture specimen of a certain specification is fixed on the rotating part of the instrument, and a certain number of abrasion media (such as steel balls or emery, etc.) are placed in the rotary screen. When the rotating part starts to rotate, the abrasion medium generates friction and collision with the surface of the asphalt mixture specimen under the action of centrifugal force, thereby simulating the abrasion process between the tire and the pavement during vehicle driving.
