Daftar Isi:
- The problem of plastic waste is now one of the world's concentrations. Efforts to reduce and prevent many have been done, but in general the results obtained are not comparable with the growing use of plastics that continues to increase, especially plastics that are not managed properly. One of the efforts made is the utilization of plastic waste as added ingredients of Laston AC-WC hot asphalt mixture called modification. The purpose of this study was to determine how the effect of adding Low Density Polyethylene (LDPE) plastic waste to the characteristics of Marshall Laston AC-WC. Tests carried out include aggregate testing, asphalt testing, and plastic testing, and Marshall testing. The design of the mixture is done by dry (dry process) using a variation of plastic content of 0%, 4.5%, 5%, and 5.5%, each of which uses 5 levels of asphalt which is 5%, 5.5%, 6% , 6.5%, and 7% with 3 specimens each, so that there are a total of 75 specimens. Marshall test results obtained KAO of 6.5% with a variation of plastic content of 5.5%, obtained stability of 2167.40 kg, Flow 3.8 mm, VIM 3.94%, VMA 15.95%, VFA / VFB 77, 12%, and MQ 570.37 kg / mm. So that the addition of LDPE type plastic waste meets (General Specifications of Bina Marga, 2018).
- Permasalahan sampah plastik saat ini telah menjadi salah satu konsentrasi dunia. Upaya pengurangan dan pencegahan telah banyak dilakukan, namun secara umum hasil yang didapat tidak sebanding dengan pertumbuhan penggunaan plastik yang terus meningkat khususnya plastik yang tidak terkelola dengan baik. Salah satu upaya yang dilakukan adalah pemanfaatan limbah plastik sebagai bahan tambah campuran beraspal panas Laston AC-WC yang disebut modifikasi. Tujuan penelitian ini adalah untuk mengetahui bagaimana pengaruh penambahan limbah plastik jenis Low Density Polyethylene (LDPE) terhadap karakteristik Marshall Laston AC-WC. Pengujian yang dilakukan antara lain pengujian agregat, pengujian aspal, pengujian plastik, dan pengujian Marshall. Perancangan campuran dilakukan dengan cara kering (dry process) menggunakan variasi kadar plastik sebesar 0%, 4,5%, 5%, dan 5,5% yang masing-masing memakai 5 kadar aspal yaitu 5%, 5,5%, 6%, 6,5%, dan 7% dengan masing-masing 3 benda uji, sehingga total ada 75 benda uji. Hasil uji Marshall diperoleh KAO sebesear 6,5% dengan variasi kadar plastik sebesar 5,5%, diperoleh stabilitas 2167,40 kg, Flow 3,8 mm, VIM 3,94%, VMA 15,95%, VFA/VFB 77,12%, dan MQ 570,37 kg/mm. Sehingga penambahan limbah plastik jenis LDPE memenuhi (Spesifikasi Umum Bina Marga, 2018).
