| 摘 要： | 水损害是主要沥青路面病害之一,造成水损害的外因主要有交通量、交通组成、降雨量以及不尽完善的路面排水系统。沥青路面产生水损害的内因可以归纳为沥青混和料孔隙率过大、路面压实度不足、沥青与集料间的粘附性差以及混合料不均匀。减少沥青路面水损害的措施很多,概括起来主要有路面结构设计、沥青混合料组成设计、施工工艺三方面的措施。

| Abstract: | Pavement moisture damage is one of primary asphalt pavement distresses.The external causes leading to pavement moisture damages are mainly traffic volume,traffic composition,rainfall and pavement drainage system which is not perfect.The internal causes which lead to pavement moisture damage can be summed up as large air-void ratio of asphalt mixture,inadequate compactness,bad adhesion between asphalt and aggregate and the asymmetry of asphalt mixture. There are a great many measures that can reduce pavement moisture damages.The measures are pavement structural design,asphalt mixture composition design and construction techniques. |
