A STUDY ON THE SOUNDNESS ASSESSMENT OF CONCRETE PAVEMENT OVERLAID WITH ASPHALT MIXTURE

There are many routes that were originally paved with ordinary concrete pavement, but were overlaid with asphalt pavement for some reason, mainly in routes built during the high growth period. In the case of such pavement structures, surface cracks can be determine the damage status by road surface investigation, but the joints of the concrete slabs covered with asphalt mixture cannot be investigated directly. In addition, it is often the case that the entire route has the same pavement structure, and therefore, an efficient investigation is required to cover a wide area of repair work. In this paper, in order to evaluate the soundness of the joints between asphalt mixture covered concrete slabs the authors describe the content of the method of efficiently investigating the load transfer rate which is one of the items to evaluate the joints.
