Abstract
Yokohama City has been introducing new porous asphalt mixture using modified asphalt with high viscosity and torsional resistance since 2001, to restrain aggregate stripping problem of porous asphalt pavement at intersection. According to the follow-up survey conducted in 2004, aggregate stripping is almost restrained except the place done by manual work and at the part of pavement joint. This aggregate stripping is replicated and validated at laboratory. As a result, insufficiency of the strength is observed which is specific to the asphalt mixture applied at intersection.
