The objective of this study was to analyze the effect of using natural resin and natural asphalt on the performance of flexible road pavements. Natural resin and natural asphalt are local materials that are widely available in Indonesia which have potential as binders for flexible road pavements. This material has binding properties and can substitute some of the oil asphalt. This research is a laboratory experimental using Marshall cylinder samples. The material used in this study consisted of asphalt penetration 60/70, Buton Natural Asphalt B 50/30, pine resin, and standard aggregate. The sample was made using aggregate gradation for hot mix asphalt of Asphalt Concrete Wearing Course, bituminous content of 6.5%, natural asphalt as a substitute for asphalt pen 60/70 and fine aggregate as much as 10% of the total weight of sample, and pine resin as a substitute for oil asphalt with variations 0%, 2.5%, 5.0%, 7.5%, 10%, and 12.5%. The results showed that the use of pine resin content up to 12.5% and natural asphalt as much as 10% still met the requirements specified by Indonesia Standard with Marshall Stability is 2515 kg, flow is 2.0 mm, Marshall Quetient is 1,237.2 kg/mm, and Void in Mixture is 3.6%. Here shows that the use of 12.5% pine resin and 10% Buton Asphalt can substitute as much as 42.28% of oil asphalt. This research is expected to be applied to reduce dependence on the use of oil asphalt for flexible road pavement materials.
