Abstract
Kansai International Airport Co., Ltd. has introduced the multi elastic layer analysis method to the design of the 2nd runway asphalt pavement. The cost reduction of the asphalt pavement can be realized by the appropriate estimation of reclamation land strength and by the reduction of pavement thickness. The technical issue is the determination of the elastic coefficient and the fatigue failure criterion of the subgrade that include D300 m/m rocks in the maximum. The economical structural design of the new runway pavement has been made based on the result of the on-site test using the loading vehicle (B747).
