基于弯沉盆参数的沥青路面动态弯沉综合修正系数
Dynamic synthetic deflection correction factor of asphalt pavement based on deflection basin parameters
摘要
Abstract
In order to establish the pavement quality acceptance standards based on dynamic parameters design method of asphalt pavement, deflection synthetic correction factor F is discussed. The nonlinear constitutive model of the subgrade soil and dynamic parameters of the other layer are used to calculate the theoretical deflection thought the ABAQUS finite element program. The deflections of indoor full-scale experiment road have been tested by falling weight deflectometer (FWD). According to the definition of synthetic deflection correction factor, the theoretical deflection and the FWD testing deflection are compared, then the F values of the experiment road of different structures are calculated. By analyzing F correction formula in the standard and the results of this study, the primary variables in correction formula F are selected, and then the new modified formula F is regressed based on deflection basin parameters. The deflection basin data of the outdoor experimental road are used to validate the correctness of the new F correction formula. The results show that the formula F regressed performs well, and its feasibility to a certain extent is proved.关键词
