Performance of coconut fiber as bitumen modifier in asphalt mixture influence to fatigue resistance

Abstract One of the most prevalent challenges faced in road construction is pavement distresses produced by ageing asphalt pavement, which resulted fatigue cracking. Fatigue cracking regarded as one primary failure types when tension bituminous layer low due to high vehicle traffic load repetition. The study focuses on evaluating performance coconut fiber modifier bitumen penetration grade 60/70. addition 0.5%, 0.75% and 1% were used this determine effect mixture. Indirect tensile test conducted life cycle sample. result showed that increasing percentage will improve physical properties increased In study, best result. conclusion, into can mixture term resistance.
