Pemanfaatan Limbah Plastik sebagai Bahan Tambah Campuran Aspal pada Pekerasan Jalan AC-WC Terhadap Nilai Marshall

Abstract

Road is the basic and main infrastructure in moving the wheels of national and regional economy. In 1999 the Regional Settlement and Development department issued a new set of Hot Asphalt Mixed Planning Guidelines Under the Absolute Density Approach. One of the new specifications issued is the asphalt concrete - wearing course (AC - WC) as the 2nd layer of coating in the asphalt concrete layer is the topmost layer in flexible pipe. In the mixture of AC - WC usually only use mixture of aggregate and hot asphalt, in this study added LDPE plastic material as add-on material of Asphalt substitute with the aim if show positive thing can be used in Indonesia road and also become one of plastic waste solution in Indonesia. Before Marshall testing and durability of the mixtures, the material preparation and material testing should be done after all of the specimens have been tested with 6.0% asphalt content of the total mixture. The specimens are made in 3 variations using 100% Asphalt, plus 4% LDPE plastic and 6% LDPE plastic then do the collision of 2 x 75. Marshall test results show average stability without adding plastic 4004.316 kg and flow an average of 3.10 mm of plastic addition by 4% resulting in an average stability of 4637,348 kg and an average flow of 2.92 mm plastic addition as much as 6% yields an average stability of 4670,814 kg and flow an average of 2.79 mm. After doing the Marshall test it was found that in addition to 4% of Low Density Polyethylene plastic can be used for AC-WC mixture but for addition of 6% it has shown that melting value is too small and can not be used for AC-WC layer.
