Mixture Of High-performance Asphalt Pavement Performance And Its Application

asphalt concrete pavement has become one of the most leading asphalt pavement forms ,but with the development of national economy, there are many phenomena as follow: traffic amount increasing; larger vehicles, overload problem and the destruction of high temperature. These phenomena lead questions as such: inadequate durability of the pavement, rut,deform, destruction of high temperature. All these decrease the service life of pavement and reduce the service level of pavement.According to traffic condition,nature condition, the material for pavement and the demand for pavement service, the article has focused on the structure and the component of asphalt mixture.At first analysed the different gradations and the technology demand of asphalt mixture. By the tests indoor,the article has gone on a series of tests about the different gradations of asphalt mixture, mostly analysed the influences of fibre's mixing into the mixture.By the analysis of a great deal of data,it has verified that fibre being mixed into the asphalt can improve the use performance of pavement.At the same time by the analysis of test indoor and theory we can build a trail pavement.Then with the observation and analysis, to validate the use performance of modified asphalt for pavement mixture.aiming at the questions to improve and perfect.At last,based on the theory analysistest,the test indoor, the building of trial pavement,to analysis systematically the technology and economy performanceof advanced asphalt concrete mixture,and recommend the fitting mix ratio of advanced asphalt concrete mixture.
