17. Marketplace Determines Feasibility
Contractors see potential for cost savings
Contractors see “green” benefits
Contractors see risk (DNR / OSHA)
IDOT sees benefits in lower prices and green initiative
IDOT places specification burden on RAS suppliers thus allowing contractors to try using RAS before becoming recyclers themselves

18. Conclusions
APAI’s role is facilitator between contractors and public agencies including IDOT, county, city and consulting engineers
IDOT is the “rule maker” for all of Iowa
RAS is beneficial to asphalt
The success of RAS will ultimately depend on the marketplace and regulatory agencies
