Basic Test of Geotextile Three-dimensional Reinforced Soil Method Application for Railway's Base Course

Abstract

The basic tests were performed to verify the application of the Geotextile of Three dimensional Reinforced Soil method (G. T. R. S) for the railway's base course.Plate loading test and CBR test were carried out on the top of embankments reinforced by two construction methods, mixing mesh-elements with sand and mixing continuous thread with sand which belong to the G. T. R. S.The results of these tests show that reinforced embankment made by mixing continuous thread with sand has sufficient bearing capacity which meets the JR standard of earth base course. Therefore it is concluded that only continuous thread-reinforced soil is possible to adopt for the railway's base course in case of static condition.
