Opportunity applying response surface methodology (RSM) for optimization of performing butonic asphalt mixture using plastic waste modifier: A preliminary study

Abstract

Abstract Non-biodegradable waste plastic made of polyethylene terephthalate (PET) based drinking bottles waste was used as additive in asphalt concrete mixture production. This paper used modified Buton asphalt (MBA) as base binder. The asphalt concrrete mixtures containing 0%, 0.5%, 1.0%, 1.5%, 2.0% and 2.5% of waste PET were prepared with one source of aggregates, filler and stone dust. The effect of waste PET and MBA to asphalt concrete mixture on volumetric properties namely specific gravity, void in mix (VIM), void mineral aggregate (VMA) and void filled bitumen (VFB) is studied. The results of volumetric evaluation indicated that waste PET and MBA could be incorporated in asphalt concrete mixture. After calculating specific gravity, VIM, VMA and VFB, a table was designed as a preliminary study based on Response Surface Methodology (RSM) that can be used as a basis of modelling for continuous improvement of asphalt concrete prepared with waste PET and MBA.
