A Fast and Non-Destructive Prediction Model for Remaining Life of Rigid Pavement with or without Asphalt Overlay

Remaining life is an important indicator of pavement residual effective service time and directly related to maintenance decision-making with limited funds. This paper proposes a fast non-destructive model predict the remaining rigid PCC (Portland cement concrete) pavement, or without asphalt overlay. Firstly, was constructed according current Chinese design specifications for concrete integrating inverse concept. Secondly, prediction applied three typical sections 1430, 1250 1000 slabs, respectively. Ground penetrating radar (GPR) utilized determine geometric parameters in predictive physical state pavement. A falling weight detector (FWD) determination mechanical parameters. more reasonable equivalent elastic modulus foundation back-calculated instead using specification. Thirdly, predicted based on The distributions statistically analyzed. Finally, system inform strategy proposed technical condition each slab. results showed that relationship between parameters, highly consistent engineering experience. success rate as high 96%. good applicability feasibility. shown be feasible terms economic benefits.
