The Application And Research On The Superpave Technology Using In GanDing Expressway

Superpave (Superior Performance Asphalt Pavement) is consisted with three parts which include specification of asphalt binder, mixture design and analytic system and computer system. It basically revised the empirical character of current test methods and specifications. We are introducing this system into China, but the set of SHRP equipments is very expensive and the situation is different between China and USA. So it needs to combine the situation of our country to make the best result. On the basis of the analysis and conclusion on the domestic and foreign study state of Superpave, this paper selected the raw materials local in GanZhou area, studied the application of Superpave in GanZhou.Firstly, this paper analyzes the climatic environment of GanZhou area and classifieds climate sub region of the area. It bring forward a way to select binder based on different position of asphalt pavement and solve some problem of Performance Grade system. Then it studies the SGC, Mashall and Large Mashall based on pavement performance. In addition, this paper discussed the construction techniques of Superpave mixtures, and presented the practice of trial road as a reference to the application of Superpave in the future.
