水泥用量对冷再生混合料路用性能影响规律

通过室内试验研究了水泥用量对乳化沥青冷再生混合料高温稳定性、低温抗裂性和水稳定性等路用性能的影响。试验结果表明,增大水泥用量能很好地改善乳化沥青冷再生混合料的高温稳定性和水稳定性,而大的水泥用量虽然增大了混合料的破坏应力,但使破坏应变大幅减小,混合料的低温抗变形能力变差。

Through indoor tests studied on the influence of cement content on the high temperature stability, low temperature anti - cracking performance and water stability of emulsified asphalt cold recycling mixture. Test results show that increasing the cement dosage can well improve the high temperature stability and water stability of emulsified asphalt cold recycled mixture. Though large dosage of cement increased the mixture failure stress, the failure strain decreased sharply, and the low temperature resistance to deformation of mixture becomes poor.
