摘要
对不同水泥掺量(0～5%)的乳化沥青冷再生沥青混合料进行了力学及路用性能测试研究。结果表明,掺加一定用量的水泥能显著影响乳化沥青冷再生混合料的力学和路用性能。随着水泥掺量的增加,其混合料的力学性能、高温稳定性及抗水损害能力随之提高,具有明显的规律;而低温性能呈现先增加后降低的变化特性,当水泥掺量为1.5%时,冷再生混合料具有最佳低温抗裂能力。
Emulsified asphalt cold regeneration mixture of cement admixture 0-5% change condition, the change rate of different cement dosage cold regeneration mixture on mechanics and road performance research. The results show that, adding a certain amount of cement can significantly improve the emulsified asphalt cold regeneration mixture mechanics and the road performance properties. At the same time, with the increase of cement admixture, the mixture mechanical properties, high temperature stability and resistance to water damage ability along with it enhancement, it has obvious regularity, and low temperature performance first increased and then decreased change characteristics when cold regenera tion mixture with the best low temperature cracking resistance of the cement content of 1.5 %.
