Slope stabilisation and protection for roads in mountainous terrain with high rainfall

The south east asian region which lies in the heart of the tropical monsoon belt is subject to some of the most intense and frequent rainfall in the world. Several highways that traverse mountainous terrain in this region have mostly residual soils forming part of roadway cuttings (in full cut or on part cut/ part fill) and fill slopes. These are known to be affected constantly by erosion and/ or stability problems attributed to rainfall. Drawing on the experience in the rectification of these problems on the east west highway project, peninsular Malaysia, the various methods of slope stabilisation and protection are described. Particular attention has been given to the use of surface and subsurface drainage as one of the slope stabilisation measures and to biotechnical techniques (use of vegetation/ shrubs, trees) for erosion control. The importance of maintenance in the post construction period is advocated (a).
