LABORATORY VERIFICATION OF PERFORMANCE OF PIER DECK PAVEMENT FOR NEW RUNWAY D AT TOKYO HANEDA INTERNATIONAL AIRPORT

The fourth runway at Tokyo Haneda International Airport is planned to be in part an asphalt pavement on a pier deck. The pavement consists of asphalt mixture layers of three different types: a dense graded, a drainable and a stone mastic asphalt mixture. Their performances were studied in various laboratory tests, and the following results were obtained. 1) A dense graded asphalt mixture with polymer-modified asphalt has sufficient durability when subjected to repeated loading and with respect to the segregation of the mixture. 2) Adhesion between the asphalt mixture layer and the concrete slab is verified after repeated wheel-track loading, even under submerged conditions. 3) The three asphalt mixtures composing the surface and binder courses on the concrete slab have sufficient fatigue resistance.
