随着交通量迅速增长,在车辆载重增加和自然因素的作用下,路面平整度、抗滑能力等路用性能逐渐降低,并出现车辙、裂缝、拥包、脱皮、坑槽等路面损坏,大大影响了其使用的安全性、舒适性、经济性和通行能力。结合旧沥青混凝土路面处置后的现状,考虑到交通需求和经济因素,在损坏路面加铺一层SMA-13改性沥青混合料层
With the rapid growth of traffic volume, road performance such as road surface flatness and anti-skidding ability gradually decreases due to the increase of vehicle load and natural factors, and the road surface such as rutting, cracks, bagging, peeling and pit damage is greatly affected. Affecting the safety, comfort, economy and capacity of its use. Combined with the status of the old asphalt pavement after disposal, taking into account traffic demand and economic factors, add a layer of SMA-13 modified asphalt mixture layer on the damaged pavement
