This paper is a review of the chemical and physical properties of coconut fiber in asphalt mixtures. Coconut fibers (CF) are natural fibers and also an agricultural waste, which is abundant after the extraction of juice and coconut fruit. Nowadays, CF has been studied for its potential use in the construction field to increase the strength of materials with its high tensile strength. Additionally, CF can also be one the materials in highway construction as it can improve the skid resistance of asphalt pavements. It was shown that CF treated with NaOH lowered the penetration value and increased the softening point of modified bitumen. Flow of bitumen also can be avoided at high mixing and compaction temperatures by adding 0.7% of CF.
