水泥混凝土路面强度高,养护费用省,经久耐用,能适应重交通量通行,是一种有很多长处的高级路面。但是修建时投资大,损坏后修理困难。因此,对修建公路水泥混凝土路面问题,一直有着不同的争议,使水泥混凝土路面的发展,时高时低成为波浪形前进。就是世界上很多国家对修建水泥混凝土路面,也是因受能源和其他条件的限制,时有起伏,到近一二十年,水泥混凝土路面才有了较大的发展。如美国水泥混凝土路面占整个高级路面的
Cement concrete pavement strength, conservation costs, durable, able to adapt to heavy traffic, is a kind of many advantages of the senior pavement. However, the construction of large investment, repair damage after the damage. Therefore, the construction of highway cement concrete pavement problems, there has been a different controversy, so that the development of cement concrete pavement, high and low into a wave-shaped progress. That is, many countries in the world are cement concrete pavements, but also due to the constraints of energy and other conditions, sometimes ups and downs, to nearly a decade, only a great development of cement concrete pavement. Such as the United States cement concrete pavement the entire high-grade pavement
