简述了车辙病害的形成机理和预防措施,分析了车辙王抗车辙剂的作用机理,比较了添加不同掺量车辙王抗车辙剂的AC-20型沥青混合料的高温稳定性、低温抗裂性和水稳定性指标。发现了添加车辙王抗车辙剂能显著提高沥青混合料的动稳定度,同时能改善沥青混合料的低温抗裂性能和水稳定性。通过铺筑试验段,表明只需适当延长拌和时间和提高施工温度,就可以保障掺车辙王抗车辙剂的AC-20中面层的施工质量。
The formation mechanism and precautionary measures of rutting disease were briefly introduced. The mechanism of rutting resistance was analyzed. The high temperature stability and low temperature crack resistance of AC-20 asphalt mixture with different dosage of rutting agent were compared. Sexual and water stability indicators. It is found that adding rutting rutting anti-rut can significantly improve the dynamic stability of the asphalt mixture and improve the low-temperature crack resistance and water stability of the asphalt mixture. By paving the test section, it shows that only by properly extending the mixing time and increasing the construction temperature, the construction quality of the AC-20 middle layer of the rutting-resistant rutting agent can be ensured.
