沥青玛蹄脂碎石混合料在路面施工中的应用

The application of stone mastic asphalt mixture in pavement construction

结合济南二环东路高架桥工程沥青路面的铺筑技术,研究了沥青马蹄脂碎石混合料(SMA)技术性能及施工特点。结果表明沥青玛蹄脂碎石混合料弥补了传统沥青混合料的缺陷,使其使用性能更加全面,而改性沥青马蹄脂碎石混合料又在此基础上提高了沥青混凝土路面的高温稳定性、低温抗裂性及水稳性。

Combining the technology of flexible pavement in the East of Viaduct in Jinan,the paper studies the technical performance and feature of stone matrix asphalt mixture.The result indicates that the stone matrix asphalt mixture makes up the indication of the traditional bituminous mixture,and makes the usability more comprehensive.On that basis the modified stone matrix asphalt mixture enhances the high-temperature stability,low temperature crack resistance and water stability in aspect concrete pavement.
