摘要
采用三种同岩性集料的沥青混合料进行水稳定性能、低温抗裂性能及高温稳定性能试验,结果表明,三种同岩性集料的沥青混合料的路用性能均满足规范要求,低温抗裂性能和水稳定性能劣于不同岩性集料的沥青混合料,高温稳定性能优于不同岩性集料的沥青混合料。掺加一定量的抗剥落剂,能改善同岩性集料的沥青混合料的低温抗裂性能和水稳定性能。
Test the water stability performance,low temperature crack resistance and high temperature and stability performance of the three types of the asphalt mixture of the same rocky aggregates,the results show that the performance of the asphalt mixture of the same rocky collection material meet the standard requirements,low temperature crack resistance and water stability performance is inferior to different rocky asphalt mixture,high temperature stability performance is better than different rocky asphalt mixture.A certain amount of anti-peeling agent is mixed,which can improve the low temperature crack resistance and water stability performance of the same rocky asphalt mixture.
