Solutions to Mitigate Dowel/Tie-Bar Propagated Cracking
The goal of this project is to identify the cause(s) and contributing factors of concrete pavement longitudinal and delamination cracking caused by dowel and/or tie-bars. This will be accomplished by reviewing existing literature and developing case studies of projects in NRRA member states exhibiting dowel and/or tie-bar related distresses. Based on the case studies, Contractor will be responsible for proposing analytical and/or laboratory experiments that will enable the development of solutions that mitigate longitudinal and/or delamination cracking caused by dowel bar and/or tie-bar stresses.
