水损坏是沥青路面病害的一种主要形式，各国的沥青路面都存在不同程度的水损坏。这种损坏通常的表现是沥青从集料表面剥落，沥青混合料粘结力损失，路面强度和稳定性降低，伴之出现各种病害，严重影响了路面的使用性能与耐久性能。沥青从集料表面剥落，在某些环境下先于其他路面病害发生，它是其他病害发生的诱因之一，因此，预防水损坏，改善沥青混合料水稳定性已经上升到越来越重要的地位。
Water damage is one of the main forms of asphalt pavement diseases, and there are different degrees of water damage in asphalt pavement in various countries. This kind of damage is usually manifested by the asphalt peeling off from the aggregate surface, the loss of cohesion of asphalt mixture, the reduction of pavement strength and stability, accompanied by various diseases, which seriously affect the service performance and durability of the pavement. Asphalt peeling off from aggregate surface is prior to other pavement diseases in some environments. It is one of the causes of other diseases. Therefore, it has become more and more important to prevent water damage and improve the water stability of asphalt mixture.
沥青混合料水稳定性可以通过材料选择、混合料设计、路面结构设计、施工等方面来改善，其中材料选择是基础，在众多材料配伍中，不改变原设计配合比，只添加抗剥落剂是简而易行、性价比优良的一项措施。
The water stability of asphalt mixture can be improved by material selection, mixture design, pavement structure design, construction and other aspects. Among them, material selection is the basis. In many materials compatibility, it is a simple and easy measure to add only anti stripping agent without changing the original design mix proportion, with good cost performance.
