Rubber Asphalt Study for Wisconsin

Rubber modified asphalts have been used for years throughout the United States. Such products have indicated potential for improved pavement performance by delaying cracking and improving rut resistance. The use of recycled rubber also has the added benefit of responsible disposal waste material in a manner that may provide engineering benefits to asphalt pavements. Wisconsin DOT (WisDOT) was invited to participate in a demonstration project in2015 on the Illinois Tollway using a dry process rubber in a Wisconsin mixture design. The section, although still young, is performing well. The performance testing of the mix identified potential benefits in terms of decreased moisture sensitivity, increased rutting resistance (Hamburg Wheel Track), and reduced cracking potential (Disk-shaped Compact Tension). Currently, there are Wisconsin suppliers of both the dry process and wet process rubber modifying systems. In order to take advantage of rubber availability, WisDOT needs to become more familiar with the products, how to work with these mixtures, how to specify them, and how to gauge performance.
