| 摘 要： | 旧水泥混凝土再生骨料是一种新材料，必须对其路用性能进行研究。以旧水泥混凝土路面废弃混凝土块为研究对象，破碎后进行筛分，并对水泥稳定再生集料进行抗冻性能研究，结果表明水泥稳定全部再生骨料的抗冻性明显高于水泥稳定石屑，进而提出增加水泥稳定集料抗冻性能的具体措施，可为类似工程提供借鉴。 |
| 关 键 词： | 旧水泥混凝土 再生骨料 抗冻性 |

| Abstract: | Recycled aggregate of old cement concrete is a new material and it is necessary to study the road performance. Taking the abandoned concrete of old cement concrete pavement as the study object, it is crashed, then classified. At the same time the anti-frozen performance of cement stabilized recycled aggregate is studied. The results show that its anti-frozen performance is superior to that of cement stabilized stone chip. What＇s more, the detailed measures about improving the anti-frozen performance of cement stabilized aggregate are put forward. All these can provide reference for similar engineering. |
| Keywords: | old cement concrete recycled aggregate anti-frozen |
