ABSTRACT

ABSTRACT: An analysis of the maintenance and investment costs was carried out in order to contribute for the road traffic operation. Based on the concepts of resilience or deformability of the asphalt mixtures, the sensibility of the maintenance costs in some reference pavement structures in which the asphalt layer has different values for resilient modulus were analyzed. In the methodology under use, the variation in the loading time was taking into account in order to obtain the value of the resilient asphalt modulus, by simulating the variation of the vehicle speed in situ. The application of the capacity and service level concepts of TRB (Transportation Research Board) made possible to quantify the increment in the maintenance costs based on the decreased capacity in the transversal section of the highways. It is also presented the evolution of the maintenance costs due to highway traffic increase at different service levels.
