Pavement Pre- and Post-Treatment Performance Models Using LTPP Data

This paper determines that pavement performance in International Roughness Index (IRI) is affected by exogenous interventions such as pavement age, precipitation level, freeze-thaw level, and lower level preservation maintenance strategies. An exponential function of pavement age was used to represent pavement IRI performance curves. Moreover, this paper demonstrates a method which calculates short-term post-pavement performance models from maintenance effect models and pre-treatment performance models to avoid endogeneity bias but is still integrated with effects of maintenance activities on pavement performance.
