Summary: The study examines the impact of asphalt binder's high-temperature theological properties on the rutting resistance of hot-mix asphalt (HMA) using the multiple stress creep and recovery (MSCR) test. The results show a strong correlation between the nonrecoverable creep compliance parameter and HMA rutting performance, while the percent recovery parameter has the potential to determine the presence of modifiers in asphalt binders.

Summary: The development of the multiple stress creep and recovery (MSCR) test has improved the evaluation of rutting susceptibility of asphalt binders. However, the current test protocol's creep and recovery times may not be adequate for predicting performance under extreme traffic conditions for highly modified binders. Longer creep and recovery times had a significant impact on the MSCR test for a highly modified asphalt binder, indicating the need for further investigation to refine the test protocol and criteria for slow or standing traffic.

Summary: The full-scale experiment at FDOT's APT facility evaluated the performance of HiMA binder compared to PMA binder, showing better rutting and fatigue cracking performance under similar conditions. However, the additional 0.5% HiMA binder content had minimal impact on performance improvement. Supplementary laboratory tests confirmed the improved properties of HiMA binder and mixtures.

Summary: The use of polymer modified asphalt is increasing steadily due to the growing demands in asphalt pavements for higher loading. Higher dosages of polymer modification, known as highly or heavily modified asphalts (HiMA or HP), are now being used to enhance performance and durability of asphalt mixtures. Results show that HiMA asphalt exhibits better long-term mechanical performance in road projects compared to conventional polymer modified binders.

Summary: Polymer-modified binders (PMB) have been widely used to increase asphalt pavement durability, with SBS elastomer being the most commonly used polymer. In highly-modified asphalt binder (HiMA), the polymer content is significantly higher, leading to significant changes in binder properties. The use of HiMA positively affects the viscoelastic properties and strength of asphalt concrete mixtures.
