Slope & Road Maintenance

Slope and road maintenance is one of the specialties of our company, Warisan Pahlawan (M) Sdn Bhd. Slope failure is a common problem for roads in mountainous areas. Causes of slope failure include removal of lateral support, pressure from water and structures, earthquakes, removal of underlying support, lateral pressure, weak material, faults, slope orientation, weathering, and changes in intergranular forces. Types of slope failure include falls, topples, slumps, glides, slides, and creep. Investigations of slope failure should be flexible, and require mapping and data collection, field studies, and laboratory testing. Appropriate slope design considerations are discussed for igneous rocks, metamorphic rocks, sedimentary rocks, sands, and clays. Slope stabilisation measures include excavation, incorporation of retaining structures, use of reinforced earth, use of geosynthetic materials, and drainage. Drainage has the widest applicability for improving the stability of slopes or correction of slides, because it reduces the effectiveness of excess pore water pressure, one of the principal causes of instability. Most slope stability problems after construction can be prevented altogether, or corrected by slope design using information from geotechnical studies. Warisan Pahlawan (M) is one of the road concessionaires in Terengganu that maintains the State Roads in Terengganu under a performance-based contract. The contract scope includes routine and periodic maintenance activities on roads and its related assets.
