| Abstract: | The modified Coarse Aggregate Void Filling method is adopted to design stone matrix asphalt SMA-5, with the whole design process and a corresponding modification equation being presented. Then, the performance of the designed SMA-5 asphalt mixture is tested. The results indicate that SMA-5 asphalt mixture is of good pavement performance and superficial performance, which makes it a !suitable material for thin overlays in preventive maintenance, thus saving the construction time and decreasing the cost. |
