In this study, Several types of geotextile was used on the selected track-bed. The use of geotextile prove a economical and efficientmean to prevent the problem of mud-pumping and settlement. Field testing sections from Mock-haeng to Dong-ryang in the Chungbuk lines in Korea were selected to investigate in current condition the of track and roadbed. This testing site was divided into 5 sections. In the four sections, different types of geotextiles were installed. In order to estimate for performance of the reinforced section with geotextiles on the soft ground, four different geotextiles were installed and compared with no reinforced section. Also, after the installation, mud-pumping, settlement of elastic or plastic sleeper, failure of track, wheel-loads, and earth pressures were investigated. The following is the summaries from the field tests. As a conclusion, According to naked eyes investigation, mud pumping didn't happen at reinforced sections, but no reinforced section was happen to a top of track for 6 months. And Elastic displacements at the reinforced and no reinforced section were about 30.7% and 73.8%, respectively. Also, It was found that plastic displacement in reinforced section was retrained about 50% more than that in no reinforced section.
