This paper present the engineering properties of asphalt (AC 60/70) modified with different ratios of natural rubber. Then select the best properties of the binder to mix asphaltic concrete. From laboratory testing results with adding 6% natural rubber into mixtures for the best results. The properties of asphaltic concrete can be improved by adding 6% natural rubber. For asphaltic concrete Marshall Stability increased and flow decreased with adding natural rubber into asphalt. Comparing to ordinary asphaltic concrete (AC 60/70) the rutting resistance was increased 22% for natural rubber modified asphalt respectively. Moreover the fatigue resistance of natural rubber modified asphalt improved to be 2.06 times compared to AC 60/70.
