The Performance of Styrene Butadiene Rubber on the Engineering Properties of Asphaltic Concrete AC14

Abstract

This study investigated the effects of adding various percentages of styrene–butadiene rubber (SBR) on the engineering properties and performance of asphaltic concrete. SBR was added into the mixture at 0%, 1%, 3%, and 5% on a mass-to-mass basis. Conventional bitumen used in this study was 80/100 PEN. The performances of SBR on the asphalt mixture properties were evaluated based on Marshall Stability, abrasion loss, resilient modulus, and dynamic creep test. Results indicated an improvement in the engineering properties and performance with the addition of SBR content. For instance, stability increased by 18.8% as the SBR content increased from 0% to 5%. Dynamic creep stiffness also increased by 46.2%. Similarly, the resilient modulus was also found to increase by approximately 84.6%.

Effect of Charcoal Ash Coconut Shell from Waste Material at Different Size on the Physical Properties of Bitumen

“…Over the past decades, many studies explored the effects of natural additives on the properties of conventional bitumen [1][2][3]. The current use of coconut shell (CS) as a modifier in bitumen or replacement of aggregate in asphalt mixture has drawn considerable attention among researchers [4][5][6].…”
