| 摘 要： | 针对高速公路沥青路面的病害,采取预防性养护沥青罩面层材料进行抢救.采用车辙试验,研究了其高温稳定性能.结果表明,45min和60min下的竖向车辙变形影响高温稳定性能,级配1在60℃和68℃温度下75次和100次击实成型条件下向变形与动稳定度变化率最小,高温稳定性最好,将作为推荐级配.

| Abstract: | Directing against failure of asphalt pavement,preventive maintenance hot-mix overlay material was adopted to solve the problem. Rut test was used to study its Properties at high temperature. The results indicate that Vertical rut deformations at 45 min and 60 min can influence the properties. Aggregate grade one has the smallest deformation and stability changing rate at 60 ℃ and 68 ℃ or 75 and 100 compacting times. Its properties at high temperature are best and the aggregate grade one is recommended. |
