This paper present the engineering properties of asphalt (AC 60/70) modified with different ratios of crumb rubber. Then select the best properties of the binder to mix asphaltic concrete. From laboratory testing results with adding 11% crumb rubber into mixtures for the best results. The properties of asphaltic concrete can be improved by adding 11% crumb rubber. For asphaltic concrete Marshall Stability increased and flow decreased with adding crumb rubber into asphalt. Comparing to ordinary asphaltic concrete (AC 60/70) the rutting resistance was increased 18% for crumb rubber modified asphalt respectively. Moreover the fatigue resistance of crumb rubber modified asphalt improved to be 1.59 times compared to AC 60/70.
