Pavements are an important of highway transportation infrastructure that constitutes an enormous investment of public fund. A tremendous of time and money is spent now and then each year on construction of both new and existing asphalt pavement. The objective of this study is to evaluate the permanent deformation characteristics of buton rock asphalt (BRA) modified asphalt paving mixtures using dynamic creep test analysis. Dynamic creep test was conducted on unmodified and BRA modified asphalt mixture using UTM25 machine. Asphalt cement of C170 was used as the base asphalt binder for unmodified asphalt mixture and BRA modified asphalt mixtures were made by substituting the base asphalt with 10, 20, and 30% (by weight of total asphalt binder) natural binder continuing granular BRA modified binder. The granular (pellets) BRA modified binder with a diameter of 7-10 mm was produced and extracted according the Australia Standard. Results of this analysis are then compared to simplify the results of unmodified and BRA modified asphalt mixtures and the conclusions are drawn.
