A review of performance asphalt mixtures using bio binder as alternative binder

Abstract

This paper provides an overview of the performance in asphalt mixture using bio-binder from biomass as alternative binder. The bio-binder considered from the previous research was produced by pyrolysis process. The aim of this study is to review the performance of asphalt mixture modified by bio-binder. The Rotational Viscometer (RV), Dynamic Shear Rheometer (DSR), Rolling Thin Film Oven (RTFO), Pressure Aging Vessel (PAV) and Bending Beam Rheometer (BBR) were conducted to evaluate the rheological properties of bio-binder in asphalt mixtures. Many previous studies focused on the chemical composition, physical properties and performance of bio-binder in asphalt mixtures. Several research studies have evaluated the viability of bio-binder in asphalt pavement mixtures. Therefore, in many of these case the bio-binder was evaluated in minimal proportions (<10 percent). This is necessary in order to identify a mixtures containing bio-binder at higher blending proportions (up to 50% replacement). Additionally, a review will be a positive step in the direction of achieving mixture modified with bio-binder has shown similar or improved performance when compared to conventional mixtures.
