Work for this current IDOT project included pavement reconstruction, soil, HMA and PCC pavement, storm sewer, culverts, curbs, gutters, sidewalks, lighting, and pavement markings on 80th Avenue from Greenway Boulevard to Timber Drive. The project also consisted of replacing the bridge carrying 80th Avenue over I-80 in the Village of Tinley Park in Will County. INTERRA is conducting testing and inspection services on soil, concrete, and asphalt. For soil samples are being collected and transported to the INTERRA laboratory. Both Proctor testing and compaction testing are being conducted to verify the stability of the embankment. For asphalt, the LR-1030.2 specifications are being implemented on this project and INTERRA is playing a vital role in creating randoms for verification, plant sampling and field density/core inspection and testing.
