Abstract
Improving the quality of the road pavement and ensuring the safety of the drivers on the road are issues of paramount importance. Cracking and rutting are two of the most common damages that occur to asphalt pavement due to environmental effects and traffic. Utilizing a modified binder is a solution for improving the pavement's resistance to these damages and enhancing pavement durability. This study investigates the performance of Hot Mix Asphalt (HMA) modified with Titan7205 polymers and then compares it with that of a control mix of modified HMA with Styrene-Butadiene-Styrene (SBS) or crumb rubber (CR). Two percentages of Titan7205 were utilized to find out which dose provided better performance. HMA was prepared by adding polymers with different percentages (3% and 5% Titan7205, 4% SBS, and 8% CR). After preparing the samples, they were tested (unconditioned and AASHTO R30) for Dynamic Shear Rheometer (DSR) testing, Cantabro Mass Loss (CML), Tensile Strength Ratio (TSR), and Indirect Tensile Tension (IDT). The results showed that the mix with 3% of Titan7205 has a similar or better performance than the mixes with the other polymer additives utilized in this study.
