【内容摘要】公路路面是由各种不同的材料,按照一定配制工艺生产并按一定厚度与宽度分层铺筑在路基顶面上的结构物,以供汽车直接在其表面上行使.由于公路路面直接承受着行车荷载和自然作用,它的质量好坏,直接影响到道路的使用品质.沥青路面和水泥混凝土路面由于具有的优点较多,故成为公路路面的主要类型,被广泛应用.但由于各种原因,沥青和水泥混凝土路面的破坏现象十分普遍和严重,缩短了路面的使用寿命,对交通安全和运输已构成威胁.因此分析研究沥青及水泥混凝土路面病害的成因,提出防治建议和方法,科学处治病害,是一个长期的课题,对我国交通发展有着至关重要的意义.

【 abstract 】 highway pavement is by all sorts of different material, according to certain configuation craft production and according to certain thickness and width of the subgrade surfacing layer on top of the structures, for cars in its surface directly exercise. Because of road surface directly under driving load and natural role, its quality, good or bad, directly affects the quality of the use of the roads. The asphalt road surface and cement concrete road surface due to have the advantage of more, it become the main types of road surface, has been widely used. But because all sorts of reasons, asphalt and cement concrete pavement damage phenomena are very common and serious, shorten service life of the road, the traffic safety and transport has a threat. So, analysis and research asphalt cement concrete pavement of disease cause, make Suggestions and methods for prevention and treatment of diseases of science, is a long-term issue of our country, the transportation development has important significance.
