Design and Study of Multi-Function Asphalt Mixture Shear Apparatus

Abstract

The shear force created by non-uniform loading on the asphalt and concrete surface is the main reason why bridge deck pavement is damaged extensively. Multi-function asphalt mixture shear apparatus is designed for dealing with this problem. After studying the composition of mechanical system and data acquisition system, design and develop the program of the system. During the study, the actual prototype is produced, and used in the asphalt mixture shear experiment. The experimental parameters can help the design of asphalt mixture and the prevention of the damage of asphalt concrete pavement.
