Effects of modifying bitumen with Asbuton on the mechanical characteristics of asphalt mixtures

Given the high temperatures and heavy traffic loads, pavements in Indonesia are prone to fatigue damage and permanent deformation. Modifying the asphalt mixtures by means of polymers is an effective but costly option. This paper shows that modification of the bitumen by means of RETONA, made from asphaltic rock which is abundantly available on Buton island, is also an effective option to increase the resistance to fatigue and permanent deformation. The paper will show the results of DSR tests performed on the RETONA binder and the recovered binder of a reference base course mixture as well as the results of stiffness tests, tension and compression tests and fatigue tests. It is shown that replacing the bitumen with only 20 per cent RETONA already greatly enhances the characteristics of the mixture.
