Comparison of parametric and mixed effects models for the evaluation of pavement deterioration testing results

Pavement deterioration models are important inputs for the pavement management systems. The LCPC has been developed a statical methods to study the evolution law of pavement deterioration. However, these methods are suboptimal for modeling the evolution of pavement deterioration. To this end, we proposed to introduce a logistic mixed effects model (LMM) ollawing to account for the correlation between observations on the same pavement section. A comparison between SDAM and LMM model is carried out. The LMM model provides a good fit to describing the evolution law of different pavement sections
