Pemanfaatan Hasil Pengupasan Aspal Untuk Daur Ulang Campuran Beton Aspal

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%.

Penggunaan Bahan Anti Stripping Untuk Campuran Beton Aspal

This Research is Using Anti Stripping material to add roughness Asphalt Concrete mixture The purpose of this research was to obtain Marshall Properties Values On Asphalt Concrete Mixture, and determine levels of Anti Stripping Material Optimum Asphalt concrete misture based on Bina Marga spesification.Variation Asphalt content to Mixture are 5.0%; 5.5%; 6.0%; 6.5%; and Anti Stripping material variation are 0.2%; 0.3%; 0.4% to Optimum Asphalt Content.Marshall Testing Method Based on SNI 06-2489-1991.The result of Using anti stripping Material for Asphalt concrete mixture showed that with Optimum asphalt content 6% and addition of Wetfix Be 0.3% from the weight of asphalt can increase % voids mineral aggregate,% voids in material, Marshall Quotient and Marshall stability for 1.34%; 2.89%; 3.34% and 6.72%. Besides the addition of anti-stripping materials can also reduce % voids filled with bitumen (VFB), stability and fatigue of 0.82%; 2.85% and 12.72%.With the value of stability Masrshall The remaining 96.90% is a mixture of asphalt concrete has a high resistance to damage caused by the influence of water.For all characteristics confirm to specifications Marshall properties based on Specifications Asphalt concrete RSNI3 mix XXXX-2014
