DESIGN, CONSTRUCTION AND MANAGEMENT OF AIRPORT PAVEMENTS ON RECLAIMED GROUND

In Japan, airports must be constructed far from urban areas because there are few large flat sites, and sometimes they must even be constructed on land reclaimed from the sea. This causes several problems for the pavements of airports. First, the water table is generally high, causing severe damage to pavements when heavy aircraft loads are repeatedly applied. Second, the vertical stress acting on the subgrade is higher than normal as a stiff subgrade cannot be obtained. Third, the differential settlement that often results, might require rehabilitation in the future. Other problems might also arise. This paper describes the design, construction and management of airport pavements, and then explains the present study which examined the influence of the rough runway profile on both the pilots' operation ability and the pavement structure. The current method of airport pavement construction is as follows. The influence of groundwater on the asphalt pavement is quantified through laboratory tests and field experiments. Reduction of the design CBR on the subgrade, use of asphalt stabilized material for the base, and installation of a drainage system surrounding the pavement are applied to design and construct water-resistant airport pavement. To decrease the subgrade vertical stress, use of the sandwich type asphalt pavement which introduces a stiff subbase directly on the subgrade, is studied. If differential settlement of the ground occurs, concrete pavements will suffer severe damage, in which case, reinforced concrete precast slab pavement with a cotter joint system is introduced to repair the damaged slabs. Furthermore, prestressed concrete pavements and the lift-up rehabilitation method are also used for adjusting settled pavements. The present study on the rough runway profile is conducted as follows. Longitudinal profiles of pavement are measured using a profilometer mounted in a vehicle and combined with the Global Positioning System at normal vehicle speed. The profile data obtained at an airport runway on reclaimed ground are analyzed with conventional spectral analysis and computer simulation of the response of a large aircraft. Finally, the pilots' operation ability and passengers' comfort are analyzed, and then roughness criteria for runways and taxiways are determined. In addition, loading characteristics of moving aircraft and dynamic response of airport pavements to aircraft load are studied.
