SEAM改性沥青混合料路用性能研究

Pavement Performances of Asphalt Concrete Modified by SEAM

采用高温稳定性和低温抗裂性两个指标来评价SEAM改性沥青混合料的路用性能,试验结果表明,采用SEAM改性沥青混合料可明显提高混合料的稳定度、动稳定度、破坏弯拉强度和破坏弯拉应变,且SEAM的用量越大改善效果越明显。

Two indexes of high-temperature stability and low-temperature cracking-resistance are adopted to evaluate SEAM modified asphalt mixture properties.Experimental results show that the modified asphalt mixture SEAM can obviously improve the mixture stability,the dynamic stability,flexural tensile strength and flexural strain,and the effect of improving is obvious with the dosage of SEAM increasing.
