废胶粉改性浇注式沥青混合料性能研究

浇注式沥青混凝土是桥面铺装工程中常用的混合料类型。该文介绍了将废胶粉用于浇注式沥青混合料中,采用湿拌和干拌两种工艺拌制,研究了废胶粉改性浇注式沥青混合料的性能。结果表明,采用废胶粉拌制浇注式沥青混合料是可行的,废胶粉改性浇注式沥青混合料性能能满足相关规范的要求,但其高温稳定性还需要进行深入研究。

Study on Performance of Modified Cast Asphalt Mixture with Waste Rubber Powder

The cast asphalt concrete is the mixture type commonly used in the deck paving work.The article introduces how to use the waste rubber powder into the cast asphalt mixture,and to use two wet and dry mixing technologies,and studies the performance of the modified cast asphalt mixture with the waste rubber powder.The result makes clear that it is feasible to use the cast asphalt mixture with waste rubber powder,the performance of modified cast asphalt mixture with waste rubber powder can satisfy the requirements of the relative standards and its high-temperature stability is still required to further study.
