Pavement performance modeling
Study of pavement deterioration
Pavement performance modeling or pavement deterioration modeling is the study of pavement deterioration throughout its life-cycle.[1][2] The health of pavement is assessed using different performance indicators. Some of the most well-known performance indicators are Pavement Condition Index (PCI), International Roughness Index (IRI) and Present Serviceability Index (PSI),[3][4] but sometimes a single distress such as rutting or the extent of crack is used.[2][5] Among the most frequently used methods for pavement performance modeling are mechanistic models, mechanistic-empirical models,[6] survival curves and Markov models. Recently, machine learning algorithms have been used for this purpose as well.[3][7] Most studies on pavement performance modeling are based on IRI.[8]
