Project Start Date:  10/11/2018


The objective of this proposed project is to implement what has learned and found in the previous bolt-tightening research project conducted by Iowa State. To this end, this project will: (1) produce a video for training and demonstrations; (2) provide a training session to train contractors and educate MnDOT personnel; (3) provide on-site technical support and inspections; and (4) continue to monitor an existing structure to provide long-term data for improvement and, if necessary, modifications to the bolt tightening specifications and guidelines.
