针对干线公路大纵坡路段出现的车辙病害问题,从提高沥青混凝土的高温抗车辙性能出发,对0.3%~0.35%PRPLASTS抗车辙沥青混凝土进行了配合比设计,并与SBS改性沥青混凝土进行了对比分析,研究结论表明,0.3%~0.6%PR PLAS-TS抗车辙沥青混凝土的高温稳定性能优于5%SBS改性沥青混凝土,在沿黄干线公路大纵坡路段上取得了良好的应用效果。
In order to improve the rutting resistance of asphalt concrete at high temperature, aiming at the problem of rutting in the longitudinal section of trunk highway, the mix design of 0.3% ~ 0.35% PRPLASTS anti-rut asphalt concrete was carried out and compared with SBS modified asphalt concrete The results show that the high temperature stability of 0.3% ~ 0.6% PR PLAS-TS anti-rut asphalt concrete is better than that of 5% SBS modified asphalt concrete, and good results have been obtained on the large longitudinal section of the highway along the Yellow River .
