The permeable pavement was attracted as a method of a city environmental improvement. It was introduced to subsidence occurred by pumping ground water. Application on a heavy traffic road is also considered now in connection with a recent law about control runoff in urban area. However, problems which should be solved, such as the durability, remain to apply permeable pavements on the heavy traffic road. This paper is discussed about the durability of a permeable pavement etc. from the results of the follow-up survey over about 13 years of the national highway by which test construction of the permeable pavement was carried out in Japan on the heavy traffic road in 1993.
