The objective of this research is to study the behavior under working condition of railway track reinforced with geocomposite material, i.e. geogrid and geotextile. The study is carried out at km. 67+500 to 68+000 of the Eastern line (outbound) between Don Si Non and Pad Riew Stations, Chachoengsao Province. Field experiments are carried out, which are (i) rail alignment measurement and (ii) track quality by TGM. Moreover, ballasts are collected for laboratory tests to evaluate their fouling and breakage. The results showed that the reinforcement can improve track irregularity; however, it cannot reduce ballast fouling and breakage.
