摘要
依据长寿命路面的设计理念,研究骨架密实型多碎石沥青混合料性能。沥青混合料采用30号硬质沥青,填料全部用水泥代替矿粉。对沥青混合料的高温稳定性、水稳定性、抗疲劳性能和强度性能进行了试验与分析,与国内常用的沥青混凝土(AC)路面相比,其性能有明显改善。提出了供工程使用多碎石沥青混合料的级配组成。
Based on the concept of long-life pavement, performance of skeleton densegraded stone asphalt mixtures are researched. Tests about high-temperature stability, moisture stability, anti-fatigue ability and compressive strength are conducted. The results of experimental project reveal that compared with traditional asphalt concrete （AC） pavement, the performance of skeleton densegraded stone asphalt pavement are improved. The gradation of stone asphalt mixtures is put forward.
