  • RESEARCH OF THE METHOD ESTIMATING AND MAINTAING THE SUBGRADE STRENGTH

説明

This paper concerns the development of the pavement structural design in railway container yards where weight forklifts are driving for loading works. One important objects in this paper is to estimate the subgrade strength easily. By the economical analysis on the construction cost, the minimum subgrade strength was decided as CBR 6. HFWD was introduced to estimate the subgrade strength which is more conveniently estimate the strength. The other object is to maintain the subgrade strength more inexpensively. The geotexitile was introduced to the subgrade in the yard pavement in the cold area and the construction cost was less than the conventional methods.
