Method for predicting service life of asphalt pavement

The invention relates to a method for predicting the service life of an asphalt pavement, which belongs to the technical field of road engineering and mainly comprises the following steps: determining an asphalt surface layer structure and a material ratio; manufacturing a full-thickness rut test piece, performing a rut test by adopting a full-thickness rut tester, and recording test data; establishing a relational expression of the rut deformation rate, the time and the temperature; and deforming the equation to obtain an asphalt pavement life prediction model, and substituting test data into the model for calculation to obtain a life prediction value. The method can be used for checking whether the asphalt surface layer structure selected by the newly-built pavement meets the initial use requirement or not, and a new thought is provided for optimization and application of the asphalt surface layer structure. 本发明涉及一种预测沥青路面寿命的方法，属于道路工程技术领域，主要步骤包括：确定沥青面层结构及材料配比；制作全厚度车辙试件并采用全厚度车辙试验仪进行车辙试验，记录试验数据；建立车辙变形率、时间和温度的关
