Dowel Placement Evaluation and Tolerance

Sunday, January 07, 2018, 1:30 PM-4:30 PM, Convention Center 2018
Hyumhwa Yu, Federal Highway Administration (FHWA), presiding
Sponsored by Standing Committee on Design and Rehabilitation of Concrete Pavements; Standing Committee on Quality Assurance Management; and Standing Committee on Concrete Pavement Construction and Rehabilitation

Dowel bars provide positive load transfer across pavement joints to reduce critical deflections and stresses, thereby reducing the potential for slab cracking and for pumping and faulting at joints. Proper placement is crucial to the proper function of dowel bars and pavement performance, however. This workshop summarizes known facts about the impacts of dowel bar alignment and explores specification needs to ensure good pavement performance.  A new FHWA TechBrief related to dowel bars that is anticipated to be out by the end of the year will also be shared and discussed.
