Research of Asphalt Rubber Stress Absorbing Layer Used in Prvention of Reflection Crack

摘要

This paper described the definition of the reflection crack and studied the generation mechanism of reflection crack. Based on the good elastic recovery and big viscosity, the asphalt rubber stress absorbing layer could effectively prevent the reflection crack. The raw material technical standard of the asphalt rubber stress absorbing layer is promoted. Construction technology of the stress absorbing layer is described, which can guide engineering practice.
