Laboratory Comparison of SBS and PROpolymer MA123 Modified Asphalt Mixture

Abstract

In order to enhance the properties of asphalt mix, especially rutting resistance in Iraq due to high temperature, different modifier types have been adopted. Recent studies have shown that in Iraq, the polymer in the form of SBS is highly effective and gives good results in resistance to rutting and other defects. However, its use increases the cost of asphalt concrete and its difficulty storing, leading to the investigation of alternative polymers that should be more reasonable than the SBS polymer. This study examined a polymer named PROpolymer MA123 to measure its applicability to modified asphalt mix. For this purpose, the Asphalt mix was modified with 0.5% of PROpolymer MA123 from asphalt weight. The results showed that applying the new alternative polymers resulted in equal or better performance than the SBS-modified samples.
