Abstract
Some of the factors causing early damage to Indonesia’s flexible pavement system in Indonesia were allegedly caused by several things, including the Equivalent axle load (EAL) equation incompatible with Indonesia’s situation where most heavy vehicles carry overloaded loads. One effort that can be done to avoid severe damage to the road is overlaid pavement. It is suspected that the overlay on the flexible pavement will affect the shape of the EAL equation. This paper will discuss the EAL equation before and after the flexible pavement is overlaid by measuring the pavement deflection’s value using a falling weight deflectometer (FWD). The data obtained in the form of pavement deflection value is then analyzed using the regression analysis method with the permanent deformation theory approach. From the research analysis, it is obtained that the power rank value for applying the maximum load limit regulation and the type tandem axle dual wheel (TADW) shall follow determined EAL before and after overlay to the type single axle dual wheel (SADW).
