@Article{, title={Modification AsphaltMixture Performance By Rubber Silicon Additive}, author={Asmiet Ramizy Abd-Alghafour and Taher M.A. Al-ani}, journal={Iraqi Journal of Civil Engineering المجلة العراقية للهندسة المدنية}, volume={}, number={11}, pages={76-87}, year={2008}, abstract={This study is the second stage of the paper “Study the Effect of Rubber Siliconon Physical Properties of Asphalt Cement”. This study took the effect of additives onasphalt mixture performance.Asphalt mixture has been designed by Marshall method for determining theoptimum asphalt content and geophysics properties of mix according to ASTM (D-1559 ). Rubber silicon at different percentage (1%, 2%, 3% and 5%) was added toasphalt binder and three specimens of asphalt rubber silicon mixture (ARSM) areprepared and evaluating according to Marshall method. Diametric tensile creep testASTM (D-1075) at 60 Co used to evaluating permanent deformation and modulus ofelasticity for ARSM.The study shown that the Rubber-Silicon has more effects increasing themarshal stability, air voids, and reducing the flow and bulk density compared with theoriginal mix.. Increase the flexibility properties of the mix and this appear fromreducing the permeate deformation at test temperature (60C), the reduction percentis about (30 to 70)%
