Study on Influence Factors of High Temperature and Water Stability of Stone Matrix Asphalt

Abstract:

There are a number of factors affecting on the high temperature and water stability of Stone Matrix Asphalt (SMA). However, under a concrete condition of traffic, climate and construction, together with reliable raw materials, the proportion of various raw materials are the main factors. SMA-16 is taken as an example, by using the Rutting test, Residential stability test and Freezing–thaw cycling test for analysing the impact of the modified asphalt, fiber and mineral filler proportion on SMA. The result shows that these three factors significantly impacted on the high temperature and water stability of SMA with the optimal values of 6.0-6.2%, 0.31% and 10-11%, respectively.
