Applied Research About Anti-segregation Technology Of The Broad-banding Thickness Paver

In the construction of modern Asphalt Pavement, to some extend, the pavement quality depends on the rationality of construction technology. During the traditional construction technology, asphalt concrete which directly paved is damped into the hopper of the paver from a tipper, which will lead to both material and temperature segregation, which creates the early damage of the asphalt pavement aggravate.Based on theory of extra wide great thickness construction technology, the thesis has chiefly carried on research of the following aspects:(1)This paper analyses the shortcoming of traditional construction technology and puts forward a solution, adding a paver with mixing ability, which deposits and mixes asphalt concrete again, reducing material and temperature segregation.(2)The mechanism of the mixing auger,the change model of compaction,the mechanism of forming compaction by the leveling vibration system and the principle of great thickness compaction are researched, which has practical value to the asphalt concrete pavement construction.(3)Through analyzing static and vibration model of the paver, the datum to set the vibration parameter of the leveling system and alleviate the affect of the road compaction and flatness are found.(4)The paper analyses the feasibility of the new technology basing on the application of extra wide great thickness construction technology in the Jingwuhuang(chang) highway of Jiangxi province by a mass of testing data and photos.Research on technology model of asphalt pavement mechanization construction of based on extra wide great thickness technology has not attracted much attention in China and abroad. According to the whole technology, this paper has researched the details of new technology based on the results of others achievements. In a word, this paper has both practical and academic value to the construction of the concrete pavement.
