An application of base sheet in a highway embankment: A case study in Thailand

One of the various methods for improving the stability of the road embankment is to reinforce the embankment by a certain mean. The reinforcement are always used to sustain the tensile stress induced in the embankment since the embankment materials are normally low in tensile strength. A research project was conducted to investigate the performance of the nonwoven fabric thin sheet which is used to reinforce the embankment at the base. The fabric is also expected to be able to prevent the contamination of the embankment material by the intruding mud below, and this accelerates the consolidation of the subsoils. The testing was performed at a site selected from a portion of the constructing highway linking Scmrong and Bangboh. The test tesults show some ability of the base sheet in improving the embankment stability and strength, and assisting the consolidation of the underneath subsoils especially the mud at the surface of the original ground.
