Abstract
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.
