Laboratory Evaluation of SBS Modified Bituminous Paving Mix
Publication: Journal of Materials in Civil Engineering
Volume 20, Issue 4
Abstract
This paper presents the laboratory investigations carried out to determine the various engineering properties such as physical properties of asphalt cement and (polymer modified asphalt binder) PMAB with (styrene-butadiene-styrene triblock copolymer) SBS, Marshall properties using modified Marshall method, static indirect tensile strength at different temperatures, tensile strength ratio, and resilient modulus ratio for asphalt concrete (AC) and polymer modified asphalt concrete mixes (PMAC) with SBS. The temperature susceptibility of PMAB-SBS is lower than asphalt cement. Marshall stability and flow values of PMAC mix are higher when compared to AC mix at optimum binder content. The static indirect tensile strength values for PMAC mixes were higher when compared to AC mixes at different temperatures. Moisture susceptibility of PMAC mixes is low when compared to AC mixes.
