Study On The Construction Quality Control And Of Asphalt Pavement In Guizhou Area

With the rapid development of highway construction in our country,original damages andlack of durability of asphalt pavement are still existing,and it has become a prominent problem which affects the healthy development of highway in our country.The variability of construction quality is one of the key factors leading to the early damage of pavement.Base on a large number of tests and test data,the main technical parameters which affect the construction quality of asphalt pavement such as asphalt penetration,softening point,ductility,aggregate gradation,coarse aggregate mud content and flaky particles content,asphalt mixture gradation,asphalt content,construction temperature and pavement compactness,smoothness and thickness have been studied in this paper.The level of variability,the regularities of distribution and its influence of pavement performance have been analyzed,and measures to reduce the construction variability have been put forward.In this paper,the construction quality control of highway asphalt pavement in Guizhou area has been studied,in order to provide guidance for the construction of asphalt pavement.
