Description

This paper describes briefly the state-of-the-art in terms of rutting models. Some of the
models are analysed by comparing rutting evolution prediction for a set of representative
Portuguese pavements structures and traffic conditions. HDM-4 deterioration model was
considered to be the most promising to implement in a new Portuguese Maintenance
Optimisation System (MOS).
