DEVELOPMENT OF INCREMENTAL DISTRESS EQUATIONS FOR CONCRETE PAVEMENTS: AN APPLICATION TO MODEL TRANSVERSE JOINT FAULTING

Abstract


This paper briefly describes a global methodology to develope incremental equations for pavement distress prediction,which are very useful to evaluate in-service pavements. Such methodology is subsequently applied to model transverse jointfaulting in concrete pavements, considering joints without dowelbars. The results show that models obtained from statisticalregression of incremental distress data, compared with absolute distress models, seem to have very similar capacities tosimulate distress progression. However, the incremental equations developed in this study have many limitations caused bya large incidence of different error sources and by the lack of enough information of distress progression in the observedpavements.
