TY - JOUR PY - 1992// TI - Effect of axle load on chilean concrete pavements JO - Proceedings: International Technical Conference on the Enhanced Safety of Vehicles A1 - Faraggi, V. A1 - Ocampo, G. SP - 291 EP - 298 VL - 1992 IS - N2 - The purpose of the research described in this article is to analyze the effects of maximum dual axle load variations upon concrete pavements in Chile. The study analyzes the deleterious effects of 6 different heavy vehicle configurations with axle load variations of between 10 and 13 tonnes. Seven different rigid pavement designs and thicknesses were used in the study. The changes in pavement condition are evaluated using the AASHTO method, using a final serviceability index of 2.5. The concept of "truckload Habit" (ie the set of commercial vehicle characteristics which influence the principal costs involved) is used when quantifying the influence of maximum axle loads limits upon the pavement damage produced by heavy vehicles. Traffic forecast figures are obtained for the National Road Directive and the variations of truckload habitat with different dual axle load limits are calculated using the Whiteside method. The savings which can be made in pavement construction and repair for each axle load are calculated and discussed.
