Division Methods of Heavy Load and Heavy Load Traffic on Cement Concrete Pavement

At present,the axle loads of large transport vehicles have increased greatly driven by the economic interest,which has caused huge damage on the pavements of the highway.Therefore,it is nece-ssary to identify the axle loads of the transport vehicles and propose the heavy load and heavy load traffic boundaries of the pavements for all level highways in order to formulate the design method of heavy load pavements,and carry out the relevant administrative management policies.The heavy load and heavy load traffic boundaries for the cement concrete pavements of all level highways are presented by the stress analysis of pavement structure.
