沥青混凝土路面高分子聚合物注浆技术研究

Research on Macromolecule Polymer Grouting Technique in Asphalt Pavement

鉴于传统的沥青混凝土路面裂缝病害维修方法的不足,文中结合高聚物注浆技术的优点在南阳干线公路上的应用,介绍了采用非开挖高聚物注浆技术处治沥青混凝土路面裂缝病害的一种新的路面养护方法,研究了高聚物注浆技术的技术原理、注浆施工方案、冷补料修补技术竣工评价方法。实践证明,高聚物注浆技术在沥青混凝土路面维修和养护中的应用是切实可行的,为今后这种技术的推广与应用积累了经验。

In view of shortcomings of the traditional asphalt pavement cracks repaired method, in this paper based on the advantages of applying Macromoleeule polymer grouting technique in the arterial roads of Nanyang, a new pavement maintenance method is introduced, which is by means of a kind of non- excavation Macromolecule polymer grouting technique for treating the asphalt pavement cracks. The technical principle of polymer grouting, construction scheme, the repaired method of cold patching material and evaluation method of completed project are studied. Practice has proved that the application of Macromolecule polymer grouting technique is feasible in pavement maintenance and repair. It will produce a lot of experience and reference for the popularization and application in the future in the city＇s highway range.
