The Pennsylvania Department of Transportation has studied the use of Mechanical Couplers in full depth CRCP patches. The Coupler patch was designed to reduce Class 1 excavation and overall size of patch and thereby reduce costs. The Mechanical Couplers performed as designed and have continued to perform as well as the standard Tied Reinforcement patches. However, the costs were not reduced, which makes it impractical for the Department to standardize the use of Mechanical Couplers at this time.
