Pemanfaatan Hasil Pengupasan Aspal Untuk Daur Ulang Campuran Beton Aspal

Abstract

One for maintenance and rehabilitation of roads damaged is to give a new pavement layer (overlay) on top of the old pavement. However, this method requires so much road materials (aggregates and asphalt) so that make the old pavement to be unused. This research aims to introduce one method of repair pavement that utilizing the recycled materials of the old pavement, that can be use to a new pavement, to get the physical and mechanical properties concrete mixes hot asphalt as a result of recycling of the old pavement and to get the best quality of bitumen on mix hot asphalt and concrete from the recycled of old pavement. The independent variable in this research is a variation of asphalt content 5.0; 5; 5; 6.0; 6.5; and 7%, while the addition of bitumen content variation are 0.0, 0:25, 0:50, 0.75, and 1.0% of the chunks of asphalt concrete. Results of this research, performance of the mixed concrete with the recycled asphalt (RAP) and the standard mixed, indicates that the density, the percentage of voids of the aggregate (VMA), stability, flow, marshall quotient, percentage of voids of mixture (VIM) and percentage of voids that filled with bitumen (VFB) meet the specifications of Bina Marga 2010, the Optimum Asphalt Content obtained from the Marshall test of RAP and the standard mixture each by 6.79% and 6.9%.
