高等级公路沥青路面出现早期车辙的现象十分普遍 ,应该引起人们的关注。结构性车辙主要是由于施工时未充分压实、压实标准偏低、集料级配偏细以及超载交通过多所致 ;而失稳性车辙则主要是由于所用沥青粘度偏低和沥青用量偏多造成的。提出在沥青路面设计、施工和管理的各个环节应采取相应的对策措施
Early rutting of asphalt pavement in high-grade highways is very common and should attract people’s attention. Structural rutting was mainly due to under-compaction, low compaction standards, finer grading of aggregates and excessive traffic overloading. Rutting of the destabilization was mainly due to the low viscosity of asphalt used and the amount of asphalt used Too much caused. Proposed in the asphalt pavement design, construction and management of all aspects should take appropriate countermeasures
