Influence of Fine Aggregate on the Performance of Asphalt Concrete

Abstract:

The performance of asphalt concrete mixed with 3 types of fine aggregate respectively (i.e. natural sand, limestone, basalt) are compared. The results of Marshall test and rutting test show that the high temperature performance of asphalt mixture mixed with basalt is the best, that of asphalt mixture mixed with natural sand is the worst, and that of asphalt mixture mixed with limestone is between the above two. The result of immersion Marshall test show that the water stability of asphalt mixture mixed with basalt and that of asphalt mixture mixed with limestone are similar, but better than that of asphalt mixture mixed with natural sand. Therefore, it indicates that the machine-made aggregate (of basalt or limestone) have better pavement performance and environment benefit than the natural sand.
