In Malaysia, most of the pavement is made with hot mix asphalt (HMA) as this is one of the most economical materials available and it is also very suitable for the climate here. However, the HMA pavement normally required frequent maintenance and rehabilitation due to damages caused by excessive traffic loadings. Therefore, one of the alternatives to minimize the damages of pavement and to prolong the service life is to use modified asphalt pavement. HMA can be modified with filler, extender, rubber, plastic, rubber-plastic combinations, fibre, antioxidants, hydrocarbon, anti-stripping agents, waste materials and etc. This study demonstrates the properties of HMA added with coir fibre and kenaf fibre. The laboratory result reveals that both fibres are effective in increasing the Marshall stability of the ordinary HMA. The coir fibre and kenaf fibre increases the Marshall stability of the ordinary HMA by 3.2% and 9.7% respectively. Therefore, coir fibre and kenaf fibre has potential in modifying asphalt.
