Abstract
Tokyo International Airport assigned a technical task of recycling the pavement waste for construction of New B-Runway. Accordingly, an investigation was carried out on the test pavement containing recycled materials to explore the possibility. In the investigation a running load equivalent to the weight of an airplane was applied repeatedly to the test pavement. Outlining the result of the investigation, this report presents estimation of the elastic modulus of the cross section based on the multi-layer elasticity theory and evaluation of the pavement after the application of repeated loads. As a result, it was shown that characteristics of pavement damage can be illustrated by combining such factors as changes in layer thickness and reduction in apparent elastic modulus.
