Abstract

Hot mix asphalt (HMA) is a combination of approximately 95% stone, sand, or gravel bound together by asphalt cement, a product of crude oil. HMA is a mixture of coarse and fine aggregates plus asphalt binder. This research aims at evaluating the properties and performance of coconut fibre in HMA. Two sets of mixtures were prepared; control mixture and coconut fibre mixture. The control mixture was to determine the optimum asphalt content (OAC) while the coconut fibre mixture were prepared right after the OAC was obtained. By conducting the volumetric properties test such as bulk density test, Marshall stability and flow test as well as Resilient Modulus test on the control mixture, the OAC was evaluated from the plotting of four graphs. Fibre mixture were prepared by adding the optimum asphalt content to coconut fibre of 0%, 0.25%, 0.5%, 0. 75% and 1.0% by weight of aggregate. Then, volumetric properties tests and performance test were conducted. A comparison between samples of with coconut fibre and without coconut fibre were analysed. The impact of coconut fibre added to the mixture on the bulk density was not desirable. Value of stability decreases with increasing percent of coconut fibre but it is still fulfilled the JK.R requirement except for 0.75% and 1 % of coconut fibre. 0.5% coconut fibre has better resistance, has low value of tension and has highest resistance towards the permanent deformation of the pavement.
