• A report from the National Research Foundation of Korea examined the feasibility of applying a shrinkage reducing agent to latex-modified concrete to reduce shrinkage cracking.

• A project led by the FHWA in partnership with the French Roads and Bridges Research Agency developed a material-scale direct-tension test for UHPC that can be completed on cast or extracted specimens.

• Research sponsored by the Iowa DOT developed a specification detailing the proper materials, equipment and procedures for bridge deck epoxy injection.

• A project sponsored by the FHWA aimed to identify and quantify the effects of environmental factors and pavement design on pavement performance in the absence of heavy loads.
