EXAMINATION ON THE DESIGN METHOD OF THE ROADWAY TYPE PERMEABLE PAVEMENT AND THE STORAGE PENETRATION FACILITIES

Generally, the area of the container yard pavement becomes 1.5-2.0ha, length of arrival and departure lines of the railway freight facilities is necessary over 500m. Therefore, it is changeable to the case in which it deals with rain water of the pavement surface and case in which it must make drainage structure in the extension direction and in which large wheel load like the forklift works with the weak point. Permeable pavement and storage penetration facilities of the heavy wheel load correspondence were required in order to solve these problems. Then, flow property resistance of the surface course material as a problem of permeable pavement, strength of permeable subbase course and thickness design, design method of the storage penetration facilities were examined, and the verification was carried out in the experimental pavement installed in the container platforms.
