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

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
