高速公路沥青路面早期水损害机理分析及预防措施

在沥青混凝土路面多种早期病害中,水损害是最普遍、最重要的病害之一,由于沥青路面微裂隙与内部结构空隙,路面在夏季积水时的水压和冬季空隙水的冻涨对路面造成很大的破坏.目前,对水流在这一个破坏过程中的作用机理和规律还欠缺深入的研究.论文对脉动水压力作用下沥青路面水损坏的机理及导致水损坏现象的一些诱因进行初步分析,从工程的设计、施工和养护等方面提出了相应的预防措施.

Highway Asphalt Pavement Water Damage Mechanism and Its Prevention Measures

In a variety of asphalt concrete pavement early disease,water damage is the most common,one of the most important disease,because the asphalt pavement micro cracks and internal structure gap is inevitable,makes the road in the summer and winter when water pressure of frozen water up to space pavement caused great destruction.Because of the water factor to the pavement damage professionals have some understanding,but to flow in this one in the process of destruction mechanism and laws are lacking of further research.This paper [1] research conclusion to pulse pressure water under the action of water of the asphalt pavement damage mechanism and cause water damage phenomenon of some of the triggers for preliminary analysis,and from engineering to the design,construction and maintenance,the corresponding preventive measures were put forward.
