Abstract
Durability is the ability of asphalt concrete to accept repetition of traffic loads, friction, and weather and climate wear, while permeability is the ability of pavement surfaces to hold water seepage into pavement. Besides, the pore volume in the mixture is one of the most important AC-WC characteristics which are related to the level of water impermeability in the pavement layers. The purposes of this study is to investigates the effect of adding coconut fibers by 0%, 0.5%, 1%, 1.5% and 2% on durability and permeability the surface layer of Laston BC. The results obtained are the stability of the asphalt mixture in accepting the load without changing the plastic shape and following the trend of the 2nd order polynomial line. VIM values tend to rise then decrease until 48 hours immersion. It is found that the use of coconut fibers improved the impermeability properties of the surface layer of Laston BC. The value of mixed flow is influenced by the addition of coconut fibers, where if the fibers increase to 1%, then the flow will decrease. The durability value due to the addition of 1% and 1.5% coconut fibers can only be tolerated at the submergence limit of Laston BC for 30 hours while the addition of coconut fibers from 0% to 2% Laston BC can only submerged for 12 hours. The permeability values of the mixture decreases by 0.51 cm/sec for each addition of 0.5% coconut fibers.
