Abstract:
The Mississippi Department of Transportation is incorporating changes to material

specifications and construction procedures for bridge decks in an effort to reduce shrinkage

cracking. These changes are currently being implemented into a limited number of projects to

evaluate MDOT’s new Class BD concrete. This class of concrete was modeled after Kansas

Department of Transportation’s special provision for low cracking, high performance concrete

which was based on studies conducted by the University of Kansas. While Class BD concrete is

based on recommendations of the research performed at the University of Kansas, there was

limited data available for MDOT engineers to evaluate shrinkage characteristics of concrete made

with gravel and cementitious materials available in Mississippi. This research generates shrinkage

and permeability data for thirty mixtures developed with readily available materials in Mississippi.
