Brazilian road deterioration test: final report

The overloading practice increases as the control of heavy vehicle decreases. The purpose of this study is to do a continuous road assessment concerning strains, stress, moisture and temperature of pavement as well as recording dynamic load effort. This work is a result of a study developed in an experimental track located near Araranguá city, south of Brazil. The first activity considers the pavement instrumentation, with sensors installed in each pavement layer and weigh-in-motion sensors installed on the pavement surface. The second activity consists in doing the fatigue test and the complex modulus determination. The pavement mechanical behaviour is evaluated in the laboratory, which provides information to the pavement deterioration model. Then, with traffic load spectra analysis for the pavement life will then be calculated. The load spectra values are transformed into pavement deformation response to be compared to the pavement fatigue curve values. Pavement deterioration model is then loaded with different loads characteristics to simulated different conditions of deterioration.
