This report deals with the estimation of pavement materials desig moduli and models applicable to forecasting defects in pavement structures. The aim of the research project was to develop these. Measurements made on test roads were used for determining the parameter values for modelling. The report presents first the principles of using backcalculation, specifically with the progra Modulus and Elmod. The results obtained with these two programs a compared with results of measurements. Procedures used for estima the process of defects appearing in the road structures are then discussed. The models are based on survival analysis. As the resu this research project, models were developed for the purposes nam above. These models should be tested in real life conditions in o to verify their general applicability.
