【Abstract】 Heavy load traffic has great impact on the asphalt pavement structure. Based on the analysis of the traffic composition and heavy load situation of Jia-Liu Expressway, and calculation from the axle load conversion factor and cumulative annual equivalent axle load, the impact of heavy load on the design service life is analyzed. And incorporated with the analysis of heavy load impacts on the road performance of asphalt mixture, specific measures are proposed in the design and construction of the pavement structure and materials against such impacts.更多还原
