Title: STRUCTURAL PERPFORMANCE MODEL AND OVERLAY DESIGN METHOD FOR ASPHALT CONCRETE PAVEMENTS
Abstract: The development of a structural performance model for flexible pavements is described. This model consists of a set of probability-of-survival curves in which the structural deterioration of pavement structures, which are characterized with their equivalent layer thickness, is given with respect to the number of load repetitions. The equivalent layer thickness is calculated according to Odemark's theory. It is shown that the equivalent layer thickness and the survival rate of the pavement can be determined by means of deflection measurements. Furthermore, it is shown how an in situ asphalt concrete fatigue relation can be derived for the construction considered. An overlay design chart based on the equivalent layer thickness concept is given, and an example of how the developed techniques are used for the overlay design of asphalt pavements is presented.
