| 摘 要： | 利用由旧路面水泥混凝土块破碎而成的再生骨料,进行了再生修补型路用混凝土的性能试验,主要测试了其抗压强度、抗折强度、干缩变形以及抗冻性能。结果表明,所配制的再生早强型和再生快修型混凝土具有较好的力学性能和耐久性能,可用于重交通等级路面的修补。 |
| 关 键 词： | 再生混凝土 再生骨料 路用性能 快速修补 |

| Abstract: | The performance tests of using the recycled concrete to repair the damaged pavement are carried out,in which the old pavement is crushed to be recycled aggregate.By measuring the compressive strength,flexural strength,drying shrinkage and freeze-thaw durability,it is shown that both the early-strength and the rapid-repairing recycled concrete have good mechanics performance and durability,which can be utilized to repair the heavy traffic pavements. |
| Keywords: | recycled concrete recycled aggregate pavement performance rapid repair |
