This IDOT project took place in Oak Park and included resurfacing, new curbs, new gutters, sidewalk replacement, and pavement markings on Oak Park Avenue from Roosevelt Road to North Avenue in Oak Park. INTERRA performed testing and inspection services for both asphalt and concrete. For asphalt the density and temperature test results were verified to fall within the project requirements. INTERRA conducted pavement patching and made cylinder specimens which were transported to the INTERRA laboratory. Daily Observation Reports were also completed.
