高等级公路是现代文明的象征,一个国家的经济繁荣、社会进步、国际竞争等都离不开交通运输。目前我国高等级公路仍以水泥稳定碎石作为路面基底基层的主要结构形式,其在路面面层与路基中起着承上启下的重要作用,而且在路面工程的工作量中占有较大的比例。为此,设计一个经济合理的配合比显得尤为重要。 High-grade highways are the symbol of modern civilization. A country’s economic prosperity, social progress and international competition can not be separated from transportation. At present, China’s high-grade highways still use cement stabilized macadam as the main structural form of pavement base. They play an important role in pavement and roadbed, and occupy a large proportion in the workload of pavement engineering. For this reason, it is particularly important to design an economic and reasonable mix.
