目前我国高等级公路大力修建沥青路面而忽视水泥混凝土路面的发展,这在沥青价格持续增长的情况下不符合中国国情。文章论述了水泥混凝土路面在欧美国家和国内的发展现状,对沥青路面和水泥混凝土路面两种结构的经济性进行比较,得出水泥混凝土路面在造价、养护维修费用、使用年限和运营经济性等方面远优于沥青路面。针对目前水泥混凝土路面存在的不足与早期损坏现象,文章从路面设计、施工及养护等方面提出具体措施。最后提出大力发展水泥混凝土路面是当前中国公路建设的客观需求,是节约能源、保护环境、促进当地经济发展的重要战略举措。
At present, China’s high-grade highways to build asphalt pavement and neglect the development of cement concrete pavement, which in the case of asphalt prices continue to grow does not meet China’s national conditions. This paper discusses the development status of cement concrete pavement in Europe and the United States and in China. Comparing the economy of asphalt pavement and cement concrete pavement, it shows that cement concrete pavement cost, maintenance cost, service life and operation economy Far better than asphalt pavement. Aiming at the shortcomings and early damage of cement concrete pavement at present, this paper puts forward concrete measures from aspects of pavement design, construction and maintenance. Finally, it is an objective demand to develop cement concrete pavement in the current highway construction in China and is an important strategic measure to save energy, protect the environment and promote local economic development.
