Abstract:

Highly modified asphalt (HiMA) is an asphalt mixture containing asphalt binder that is typically modified with 7 to 8 percent polymer. Styrene-butadiene-styrene is most commonly used and is more than twice what is typically used in conventional polymer-modified binders. By increasing the polymer content, the structure changes to a swollen polymer with a dispersed asphalt phase, making the resulting binder behave more like rubber. HiMA is used for a range of applications, including full-depth to thin asphalt overlays under different traffic conditions. The Florida Department of Transportation (FDOT) has increasingly used HiMA to address severe rutting, fatigue, reflective cracking, and raveling. This report is a case study of FDOT’s experience and includes background, specifications, implementation, design, planning, construction, and performance.
