Abstract
To improve the reliability of pavement life-cycle cost (LCC) calculations, accurate performance curves are necessary. Conventional calculation methods obtain the typical deterioration trends of the road surface from regional data that are widely dispersed. While such methods may be effective for network-level examination, they are not effective for project-level examination: The network-level deterioration trends often differ from the project-level deterioration trends (i. e., the trends at each site). We studied a method of calculating performance curves that considers project-level deterioration trends and dispersion patterns.
