DEVELOPMENT OF NEW EVALUATION METHODS AND NEW DESIGN METHODS OF REHABILITATION WORKS FOR AIRPORT PAVEMENTS. REPORT OF THE PORT AND HARBOUR RESEARCH INSTITUTE

Non-destructive methods for evaluating the load carrying capacity of airport pavements have been developed to take the place of the conventional destructive evaluation methods. Dynaflect deflections are used for asphalt pavements and falling weight deflectometer (fwd) deflections for concrete pavements. Many studies have been made for design methods for the maintenance or rehabilitation works. Some new overlay thickness design methods have been proposed. One is a thickness design method for an asphalt overlay on an existing asphalt pavement using dynaflect deflections and another is a thickness design method for an asphalt overlay on an existing concrete pavement using three-layer elastic theory. New bonding techniques have also been developed for bonded concrete overlays and a prestressed concrete precast slab pavement has been developed to replace normal concrete pavements in which concrete slabs are placed in-situ. Finally, a new maintenance and rehabilitation system has been proposed. (TRRL)
