Permanent Asphalt Pavement Asphalt Stabilized Crushed Stone Design Method

The Asphalt Treatment Base have the ordinary bituminous mixture general characteristic, also has own some characteristics, when carries on the permanent bituminous pavement structural design, the Asphalt Treatment Base should have the anti-permanent deformation, the anti-brea bed bottom weary and the water stability request. At present the standard continues to use the protobitumen pavement design method about the asphalt stable crushed stone mixture ratio design method, is unable to highlight it in the pavement structure level function request. Therefore, conducts Asphalt Treatment Base research to have the important application value and the practical significance.This article in analyzes the domestic and foreign correlation research results in the foundation, designated four kind of the Asphalt Treatment Base blend the gradation, three kind of different asphalt (KLM90#, KLM70# as well as the KLM90#SBS modification), uses the big Marshall testing method to carry on the blend mixture ratio design. In this foundation, has systematically studied Asphalt Treatment Base blend mechanics performance, the high temperature stability, the water stability and the fatigue resistance can and so on the roads use the performance, and has conducted the research to the Asphalt Treatment Base mixed macadam various gradations efficiency assessment method.
