Flatness evolution conversion point determination method based on full-scale asphalt pavement full-life-cycle test
The invention relates to a flatness evolution conversion point determination method based on a full-scale asphalt pavement life cycle test, and belongs to the technical field of road engineering. According to the method, on the basis of a full-scale asphalt pavement full-life-cycle test, the conversion point of the asphalt pavement in the service performance damage evolution process in the full-life-cycle is found according to the correlation between flatness data and equivalent design axle load accumulated action times, and when the service performance damage decay is about to enter an acceleration period, the transition point of the asphalt pavement in the service performance damage evolution process is determined. Effective maintenance measures are adopted to improve the use condition of the pavement, the service life of the asphalt pavement can be greatly prolonged, and the method has important practical significance in improving the durability of the pavement, reducing the use cost in the whole life cycle and the like.
本发明涉及一种基于足尺沥青路面全寿命周期试验的平整度演化转换点确定方法，属于道路工程技术领域。本发明的方法，基于足尺沥青路面全寿命周期试验，以平整度数据与当量设计轴载累计作用次数之间的相关关系，发现沥青路面在全寿命周期内服役性能损伤演化过程中的转换点，在服役性能损伤衰变即将进入加速期时，采取有效的养护维修措施改善路面使用状况，可以大大延长沥青路面的使用寿命和服役年限，对于提高路面耐久性、降低全寿命周期内的使用成本等具有重要的现实意义。
