This project was for the removal and replacement of the bridge superstructure and realignment of the roadway. This project included the demolition of existing bridge superstructure and milling of existing box beam. Once beams were milled the construction of the new, wider bridge superstructure began including new bridge deck and barriers using AAAP concrete. After the new bridge deck and barriers had been constructed the roadway widening and realignment began. This work included ditch relocation and followed by benching for the new wider roadway. 8 inches of new 2A sub base was placed throughout these widened areas. While widening was taking place a drainage update was done which included new stub pipes, inlets, and 4 inch pavement base drain. Once the roadway was widened and realigned a polyester polymer concrete (PPC) overlay was placed overtop of the new bridge deck. When all grading of dirt work was complete 25mm base was placed followed by super elevation correction using 19mm. Lastly the 1.5 inches of 9.5 mm wearing was placed overtop the entire realigned roadway to complete the project.

During our time spent on T-235, we began with placing long term MPT signs and arrow boards for traffic control the duration of the project. Slab stabilization was then completed. After stabilization was complete, we transitioned right into milling and paving. Left lane both east and west bound was paved first with 9.5 mm wearing course. We were primarily involved in paving operations during this time, checking temperature, tack application rates, and yields among other existing duties. After completion of left lane, we began on the right both directions. Right lane was milled variable depth to existing concrete. Contractor sealed all cracks in concrete using ac20 and roadway was paved with 19mm binder. After binder was placed, 9.5 mm wearing was then placed on left lane. During paving operations, we was responsible for setting up and completing all sample collection. After completion of paving, sonic nap alerts were cut into roadway. Triple drop polyurea was placed on roadway for paint lines. We became very familiar with PTC mpt setups and operations. We assisted in daily requirements pertaining to traffic control and signage. Long term MPT signs were removed at the close of physical work, and entire project was complete prior to end of season.

I 79 Rehabilitation

I 79 rehabilitation consisted of 10 structure rehabilitations, new drainage and roadway surface removal proceeded with new bituminous overlay of wearing surface. Bridges were repaired both substructure and superstructure. Substructure consisted of spall repairs, pier cap encasements, and protective sealers. Superstructure repairs consisted of deck hydro demolition, latex overlay, elastomeric membrane sealer and bituminous overlay excluding Irish structures, which was complete deck replacement.
