针对中国海外道路工程项目应用英国水泥路面设计方法时出现的各种问题,首先详细分析了年平均日交通量、设计年限、增长因子、磨耗因子及重载车道载货车比例等英国水泥路面设计参数,然后说明确定沥青面层和连续钢筋混凝土基层结合路面(CRCB)、连续钢筋混凝土路面(CRCP)、无配筋接缝混凝土路面(URC)和有接缝钢筋混凝土路面(JRC)4种类型水泥混凝土路面结构层厚度的计算方法,并系统总结了英国水泥路面设计步骤,最后应用英国水泥路面设计方法解析计算了某工程实例。
In order to solve the various problems that arise when applying the British cement pavement design method to overseas road projects in China, the paper first analyzes in detail the annual average daily traffic volume, design life, growth factor, wear factor and the proportion of heavy truck lanes in the UK. Parameters, and then specify four types of CRCB, CRCP, URC, and JRC with a combination of asphalt overlay and continuous reinforced concrete foundations (CRCB), continuous reinforced concrete pavement Cement concrete pavement structural layer thickness calculation method, and systematically summarizes the British cement pavement design steps, and finally the British cement pavement design method is used to analyze and calculate a project example.
