摘要
在将水泥混凝土路面拓宽改造成沥青路面的工程中,普遍存在产生反射裂缝的问题。通过分析沥青加铺层的开裂原因及国内外防治反射裂缝的研究,结合鄂尔多斯市乌审街由水泥混凝土路面拓宽为沥青路面的改造工程实例,阐述了玻纤格栅的特性、防治反射裂缝的作用机理、施工方法、注意事项。
The problems of reflect crack existedgenerally in the project of cement concretepavement broadened to asphalt surface.Combinedwith the Wushen Rd.improvement project, theconcrete pavement was broadened from cement toasphalt;the characteristics of glass fiber grille, themechanism of preventing reflect crack, constructionmethods and cautions were pointed out throughanalyzing the cracking reason of asphalt overlay andresearches related at home and abroad.
