Enhancing railway track stiffness and sustainability through flowable dredged soil backfill
Tri Ho Minh Le
Abstract:This study investigates flowable dredged soil backfill using air-foam technology and simulates a bridge approach structure under high-speed train loads. A comparison between conventional cement-treated soil (CTB) and innovative flowable dredged soil backfill solutions reveals crucial findings: Resilient modulus tests highlight the significant impact of cement and air foam, favoring mixtures with over 210 kg/m3 cement content and less than 10% air-foam, resulting in a resilient modulus of 354 MPa.
