EVALUASI SIFAT MARSHALL DAN NILAI STRUKTURAL CAMPURAN BETON ASPAL YANG MENGGUNAKAN BAHAN IKAT ASPAL PERTAMINA PEN 60/70 DAN ASPAL ESSO PEN 60/70

Abstract

ABSTRACT Asphalt is a small component in the flexible pavement. As a binder, it is commonly needed 4 % - 10 % of total mixtures of the mix design. In the mixed design have to consider the technical aspect and another aspects including to obtain material easly on the site. There for, it is necessary to study the alternative material (asphalt) when asphalt not ready in the market any time. This study to compare both the asphalt Pertamina Pen 60/70 products with the asphalt Esso Pen 60/70 products base on the Bina Marga specifications. In order to have the best result, it is necessary to study in the laboratory to know Marshall characteristic and Structural Values (modulus elastisity and material strengthening coefficiens) on both of the asphalt Pertamina Pen 60/70 products with the asphalt Esso Pen 60/70 products on the asphalt optimum content. By using the VIM as a Marshall convensional 6 % find the asphalt optimum content value, based on it ± 0,5 % the VIM-PRD value on the 2 x 400 blow was determined. From the individual test result as well as in mixed result show that the stability value of the asphalt Pertamina Pen 60/70 products (906 kg) is lower than the stability value of asphalt Esso Pen 60/70 products (989 kg). Beside that, the Voids in Mix (VIM) as well as the PRD value indicate that the result for the asphalt Pertamina Pen 60/70 products is lower than the VIM value of the asphalt Esso Pen 60/70 products. Which caused impervious layer and the air can not filled in the mixing to result in oksidation and to be damage the asphalt. The result study show that Voids in Mineral Aggregate (VMA) Marshall value of the Pertamina Pen 60/70 products is lower than the VMA value of the asphalt Esso Pen 60/70 products. But for PRD value is invertion result. The Voids in Filled with Bitumen (VFB) Marshall as well as PRD value show that the asphalt Pertamina Pen 60/70 products bigger than the VFB value of the asphalt Esso Pen 60/70 products. The result study concerning the characteristics of both asphalt trade fulfill the requirement of Bina Marga specifications.
