Event Description/Abstract
SR 26 at CR 200E in Blackford County was constructed over a 40-ft deep peat bog. Continual settlement had been a challenge, leading to substandard vertical curves and drainage issues. Geotechnical analysis and hydraulic modeling in conjunction with county input and cooperation resulted in a unique culvert mat foundation requiring little profile grade-raise on SR 26. The design decisions resulted in project delivery of less than half of INDOT’s budget and a significantly reduced life-cycle cost.
