摘要
沥青废旧路面材料再利用一直是其资源化利用的难点和重点,其性能重塑是其再利用的关键要点。采用乳化沥青以及水泥作为废旧沥青混合料的稳定剂,研究了不同掺量水泥对冷不同再生混合料性能的影响,并分析了稳定再生作用机理。结果表明:水泥的加入能够明显的提升再生沥青混合料的无侧限抗压强度,B混合料的无侧限抗压强度略高于A、C混合料,劈裂强度和水稳定性也呈现出相同的规律。
The recycling application of waste asphalt pavement materials is an important issue,its remodeling performance is the key point of its reuse. The emulsified asphalt and cement is used as stabilizer in this paper. Effect of different content cement on the performance of waste recycled asphalt mixture was tested and the mechanism of stable regeneration was analyzed. The results show that the unconfined compressive strength of the asphalt mixture can be improved greatly by the addition of cement. The unconfined compressive strength of the B mixture is slightly higher than that of the A and C mixtures. The splitting strength and the water stability are also shown the same rule.
