Study of road damage potentials of mixed traffic

Dynamic interactions between the mixed traffic situations and the pavement are investigated through analysis of accumulated stored energy within the pavement. The proposed methodology integrates the dynamic response of heavy vehicles population within the mixed traffic with the primary pavement response and an objective pavement damage measure. The results attained from the proposed methodology revealed reasonably good correlation with the AASHO data on the rut depth. The proposed methodology is applied to establish the influence of traffic distribution, time of the day, weather temperature condition, average traffic speed and the type of traffic distribution on the accumulated stored energy of the pavement. The results show that a uniform traffic distribution can yield considerable reduction in the stored energy and thus the damage potentials of the mixed traffic.
