DuPage River Trail, Forest Preserve District of DuPage County

Over the two-mile improvement, INTERRA monitored rolling patterns for asphalt on-site and checked the density. INTERRA performed soil compaction, bearing capacity, and testing for density on CA-06 stone base. Services also provided included asphalt plant inspection for binder and for the surface. INTERRA did all concrete plant and field and material testing and inspection for the Knoch Knolls Pedestrian Bridge pictured below. All work was done for the Forest Preserve District of DuPage County (FPDDC).
