摘要
从材料、适用范围、形成机理、经济分析、施工5个方面,介绍了改性沥青新型磨耗层在高等级路面上的应用,并通过试验路的观察表明,改性沥青新型磨耗层具有快速排水、增加摩阻力、愈合原路面微裂缝和较强抗磨耗的功能,是处置高等级路面上常有的龟裂、网裂、脱皮、露骨、抗磨系数不足、渗水等病害的具有推广价值的新型施工工艺。
The article introduces the use of modified asphalt in high-grade road surface from five aspects, such as material, applicable, scope, forming mechanism, economic analysis and construction. The tests indicate that new wearing surface made of modified asphalt have functions of fast draining water, increasing friction drag, healing the micro crack of original road surface. It is the new valuable construction techndogy which handling diseases in high-grade road surface.
