橡胶沥青混合料设计施工质量控制

The quality control of design and construction of rubber asphalt mixture

简要介绍橡胶沥青作为一种新型材料,采用SMA级配组成其路面性能日益得到业界的好评与肯定。特别是其优良的高温稳定性、低温抗裂性、良好的表面性能和疲劳性能,在城镇道路建设中广泛应用。对橡胶沥青的性能、优点及橡胶粉的作用机理和生产工艺和质量控制的要点做了简单的探讨。

As a new material, the performance of rubber asphalt mixture with a SMA gradation in pavement is well affirmed and praised. Theyi＇e widely used in urban road with good qualities of stabilization under high temperature, crack resistance under low temperature, good performance on surface and fatigue. A brief discussion was given in this article on the performance and advantage of rubber asphalt mixture, the working mechanism of rubber powder in mixture and the production process and quality control during construction.
