Arrow Innovation Webinar Series

Control of Concrete Cracking in Bridges and Pavements

September 15, 2011

The Federal Highway Administration (FHWA) is pleased to offer the Webinar "Control of Concrete Cracking in Bridges and Pavements", which is based on "Control of Cracking in Concrete: State of the Art," a Circular published by Committee AFN10, Basic Research and Emerging Technologies Related to Concrete, of the Transportation Research Board (TRB) in 2006.  This Webinar is of particular benefit to State Departments of Transportation (DOT) and local highway agencies concerned with the control of concrete cracking, and contractors with the responsibility of prevention of concrete cracking in bridges and pavements.

Concrete is a quasi-brittle material with a low capacity for deformation under tensile stresses.  Mechanical loading, environment factors, and deleterious reactions such as alkali-aggregate reactions, sulfate attack and corrosion of reinforcing steel can result in the development of tensile stresses in concrete. These tensile stresses all too frequently result in cracking, both at early stages and during the service life, which can adversely affect the performance of concrete. However, the potential for cracking can be minimized by appropriate precautions in design, materials and proportions, and construction practices. These precautions will ensure that concrete can be used satisfactorily for an extended period of time without any significant loss of aesthetics, service life, safety, and serviceability.

The topics covered under this Webinar include 1) the causes of cracking, 2) testing and detecting cracks, 3) controlling cracks, and 4) practices for the prevention of cracks.  The Webinar will be presented by leading experts with knowledge and years of experience in understanding, identifying, testing, and controlling concrete cracks in bridges and pavements.
