Cracking and degradation is common mode of failure in asphalt pavements that Accepted 31 August 2017 occurs due to increasing traffic loads or even environmental conditions. For facing with these Available online damages some solutions are proposed including correction quality improvement and 31 August 2017 Keywords increasing the asphalt resistance. In this research by adding different percent amounts of black Nano carbon-black nano-carbon and polyester fibers as modifier in the asphalt mixtures and conducting several Asphalt concrete Marshall tests it was observed that adding these two additives can improve generally the Polyester fibers Marshall results. Polyester fiber causes preventing crack and damages of asphalt because of Marshall stability armed effect specification. According to the results Marshall stability is increased up to 61 . Cost analysis Furthermore an economic analysis was performed to investigate the cost of using such modified asphalt mixtures for constructing 1 km of a six line road and suitable percentages of additives were found from mechanical-economic analyses. 2017 Growing Science Ltd.
