Of Superpave Asphalt Mixture Design Method Applied Research

Superpave (Superior Performance Asphalt Pavement) is the end products in the area of asphalt and mix after the SHRP(Strategic Highway Research Programme)has been finished. Road researchers are worldwidely interested to it.This advantage technology is being introduced into China now. Not all that Americans did in SHRP are suitable to China.One of the reasons is that the SHRP's equipments are expensive, another is that there are many differences between USA's climate, hydrographic conditions, geologic conditions, ESAL's, materials and China's. We should assimilate SHRP's method and improve it according to China's facts.In this thesis, we mainly dedicate to several important questions, which will be met in Superpave's appliances in China. Firstly, introducing the selection of materials, carrying out the Superpave and Marshall tests with the selected materials. Secondly, comparing the pavement performance of Superpave and AC-1 mixture. Thirdly discussing the rationality of design indexes and the restricted zone, searching the relationship between the effect and beat numbers of Marshall, founding the relationship between specimens made by gyratory compactor and by Marshall compactor. At last, based on the Superpave test-road construction, putting forward the construction technology.
