Effect of Bio-Oil From Empty Fruit Bunch on Penetration Index of Asphalt Binder

Abstract

Bio-oil which is derived from pyrolysis palm empty fruit bunch (EFB) is expected to be a potential alternative modifier for asphalt. This study focused on the effect of bio-oil on the penetration index (PI) asphalt. Bio-oil is blended between 2%-10% by weight of virgin asphalt penetration grade 80/100. Physical properties are measured and compared with virgin asphalt by the conventional physical binder test – softening point and penetration. The penetration index (PI) values is calculated to identify the typical values of asphalt type. Based on the findings, it was found that increased bio-oil content can effectively soften the asphalt at the same time maintain the temperature susceptibility. Modification asphalt is still within the grade 80/100 PEN with the addition of 10% maximum of bio oil. The stiffness of modified asphalt need to be further improved by addition polymer for better asphalt binder properties.

Effects of Waste Frying Oil and Crumb Rubber on the Characteristics of a Reclaimed Asphalt Pavement Binder

“…Also, the binders with 25 and 40% of RAPB content incorporating the combination of WFO and CR have a comparable result as the virgin bitumen because the combination of WFO and CR gives the balance to the binder. As a result, all the binders consider as conventional paving binders concerning the temperature susceptible value of each binder [40].…”
