摘要
室内采用干法工艺添加适宜掺量的橡胶粉,分析得出沥青混合料在水稳定性、高温稳定性和低温抗裂性等路用性能均有较大提高;现场施工情况表明,橡胶粉改性沥青混合料具有胶粉添加简单、易施工且环保的优点。
Using dry methods in the laboratory by adding the appropriate rubber powder,the paper analyzes that the water stability,high temperature stability and low temperature crack resistance of the asphalt mixture has improved greatly.The construction site shows that rubber modified asphalt mixture has the advantages of adding rubber powder simply,easy construction and environmental protection.
