I-65 from State Road 44 to State Road 252, Patching and Rehabilitation

The original plan for the patching was to patch the obvious road deterioration with either full-depth or partial-depth patches, depending on the extremity of the area, but INDOT brought in a GPR expert, which resulted in a complete change of scope. The expert pinpointed areas where the original CRC reinforcement was missing from the current pavement, which proved to be vastly more extensive than the surface displayed. Our patching quantities all but tripled because of this. There are three bodies of water that pass through the project limits, which resulted in six bridge rehab projects within the contract. The first two (Big Blue River) were almost completely reconstructed. Both end bents and bearings on each end of each bridge were torn down and rebuilt, and there was full deck and bridge rail replacements in the plans as well. The next body of water heading north is Sugar Creek. These two bridges had their end bents completely reconstructed, along with a portion of the deck at each end. Their existing latex-modified overlays were milled off, with the remaining surface hydrodemolished. The bridges were patched with partial- and full-depth patches depending on the quality of the deck after demolition. The third body of water is Amity Ditch. The bridges over Amity were not in the original contract, but prior to construction, our project engineer advised they be added due to visible deterioration. The Amity Ditch bridges pair were milled/hydrodemolished and a new overlay applied, just like Sugar Creek. New joints were constructed at the deck/approach interface, but there was no end bent reconstruction. Work was performed for INDOT Seymour District through an on-call inspection agreement. Approximate construction costs are $21 million (Contract R-33860).
