The Strategic Highway Research Program (SHRP) together with the Wisconsin Department of Transportation has placed the first test sections of the SHRP-designed asphalt mixes. This is the prelude to the actual in-field evaluation of the SHRP SPS-9 asphalt specifications and mix designs. The mixes are specially designed through a system called Superpave, to account for the specific climatic conditions found in a region. The Superpave mix design encompasses 3 vertically integrated levels, each more complex than the next, that are intended to address different levels of traffic from low- to high-volume pavements. By incorporating all 3 mix-design levels, predictions are made for rutting, fatigue cracking, and low-temperature cracking. Details of the mix designs are briefly discussed.
