The Research And Application Of Asphalt Treated Permeable Base

Many domestic and foreign pavement investigations and experiences show that the water that gets into the internal pavement is the crucial reason for pavement distress or distress acceleration. Therefore, the permeable base as a part of the structure could drain the water stored in the pavement in order to extend the service period and improve the invest benefit and social impact.ATPB plays an important role in pavement drainage system. There are not any domestic researches onstructure analysis of ATPB. Associated with domestic andforeign research results, finishing a great deal of laboratory tests, the relationship between ATPB composition and performance has been studied in this paper, thegradation range in which the ATPB has a qualified performance has been recommended and the ATPB design method has also been established. Furthermore, the pavement performance about drainage ability, moisture susceptibility and high temperature stable performance has been studied. In addition, paving the test section, the construction technique and quality control has been studied and improved which accumulate the experience and promote the application of ATPB in China.
