Study On Construction Craft Of Asphalt Pavement Technology Of Heavy-traffic Road

Recently, with the rapid development of my country's economy, mileage of higher-road rapidly rises ,so highway communication cause in my country enters a new rapid development period. The using road mileage is enormously increased ,the genernal level of road is greatly advanced. At the same time ,with the economic development , the phenomenon of extremely increasing communication capacity, larger vehicle and heavy-load communication gets worst, therefore ,the traffic load of higher-road prents the following characteristic: serious overfreight , larger communication capacity and faster speed. Everyday the higher-road bears the heavy communication transport task,The early disease affects the normal pass of vehicle and leads to some bad society effect. because the maintaining department is always busying on the repare. Simultaneously, the government takes much money on maintaining the normal usage of heavy-traffic road in every year. So the early destruction problem of asphalt pavement under heavy-traffic load attract much attention. The article hopes that signification of heavy-traffic can be truly defined by the research on the current condition of traffic and vehicle-load and the deep-seated reason can be finded by combining the analysis of the early destrution of asphalt pavement under heavy-load traffic road structure ,the analysis mainly considers the road structure ,material and construction method. Besides,the article hopes that the deficiency of the construction craft of asphalt pavement can be solved , construction craft of asphalt pavement can be enhanced and the usagelife of asphalt pavement can be extended by the intruduction of ideal of new road structure and material and study of scientific construction control method and craft.
