Research on Mechanical Property of High Elasticity Stress-absorbing Band

Abstract

Authors of papers to research mechanical property of high elasticity stress-absorbing band for crack reflection of asphalt overlay on old cement pavement. Tensile ductility property of high elasticity rubber mastics and stress-absorbing band were tested and compared with crack stick on the market to analyze the mechanism of crack resistance. The result showed that high elasticity stress-absorbing band appeared elasticstretching, strengthen stage, yield and necking stage during stretching process, which same with standard elastic materials. Setting fiberglass mesh in the middle of band was better for mechanical property of high elasticity rubber mastics. Compared with crack stick, high elasticity stress-absorbing band was better for crack resistance.
