Karakteristik Aspal Buton Ekstraksi yang Dimodifikasi dengan Oli Bekas dan Plastik HDPE

Asphalt functions as an aggregate binder in the road pavement mixture. The rapid construction of roads causes need for asphalt to increase, while its availability is limited. government promoting use natural (Asbuton) alternative oil asphalt. However, performance from Asbuton not good. Uneven content and hardness are factors causing it be less effective a binder. It necessary improve by modifying bitumen separated granules extraction process. modifications were made using used high-density polyethylene (HDPE) plastic waste. Samples each variation HDPE two ways: constant 5% composition 2% HDPE. In variation, 0%, 2%, 4%, 6% used. Whereas at HDPE, 3%, 5%, 7% tests carried out were: 1) Moisture ash extracted Asbuton, 2) Penetration asphalt, 3) Ductility; 4) Loss weight, 5) specific gravity, 6) softening point, 7) flash burn points. modified known results data analysis out. showed that weight loss test, pure modification whole met requirements. penetration only 3 variations requirements, namely: oil, ductility burning all did meet Low ductility, meaning does have good cohesive properties. low point indicate easy fast burn, which affects mixing Thus, still optimize modifier so requirements firing met.
