AGENCY OR CONTRACTOR: WHO'S TO BLAME FOR "LEANER" HMA MIXES?

An Ohio Department of Transportation (DOT) study revealed that contractor-designed asphalt pavements have a lower service life than their DOT counterparts. Ohio DOT officials speculate that the contractor pavements have a lower liquid asphalt content, which is contributing to the shorter pavement life. By minimizing the amount of liquid asphalt, but meeting the required state specifications, contractors can be more competitive in bidding asphalt projects. The Ohio DOT is implementing a target asphalt specification for select projects to determine if removing economics from the bidding process by specifying the amount of liquid asphalt increases the quality of pavements.
