随着公路交通量的迅速发展,水泥混凝土路面的应用越来越摆到重要位置.但水泥混凝土路面对集料的要求高,水泥用量多,一次性工程造价大,因此工程施工往往受到限$lI。为了节省水泥,扩大集料来源,最大限度的降低工程造价,国际上公路建设者们都在积极寻求新的路而结构途径。从70年代开始,欧美许多国家就研究修 With the rapid development of highway traffic, the application of cement concrete pavement is more and more important.However, cement concrete pavement has high requirements for aggregate, large amount of cement and large construction cost, so construction is often limited $ lI. In order to save the cement, expand the sources of aggregate, and minimize the construction cost, the international highway builders are actively seeking new ways and structures. Since the 1970s, many countries in Europe and the United States have studied repair
