What We Did


Ajax Paving broke new ground with the first public-private partnership contract in Florida Department of Transportation (FDOT) history. The I-75 Design-Build Finance (iROX) was a $455 million contractor- financed project that widened 30 miles of I-75, reconstructed the Immokalee Road Interchange, refurbished 24 bridge structures and installed 24 new storm-water ponds. In total, the project used 450,000 tons of HMA and warm mix asphalt.

Completed 150 days ahead of schedule, iROX won FDOT’s 2010 Best in Construction Alternative Contract and NAPA’s Asphalt Awards. The project was also included on the 2010 Roads & Bridges Magazine’s Top 10 Projects in the USA.
