Abstract
It is of great importance to predict performance curve from a viewpoint of life cycle cost analysis in a pavement management system. Although the pavement performance depends on many factors shch as a pavement profile, traffic and environmental conditions, it is ofen represented by a simple model with a few key factors of cumulative traffic volume and a number of years in service.
This paper demonstrates gradual deterioration of pavement structurs using elastic multi-layer analysis along with environmental and loading conditions at each passage of vehicle. From the deterioration, cracking ratio, ruting depth and a performance curve of MCI are predicted.
