The CP Road Map E-News is the newsletter of the Long-Term Plan for Concrete Pavement Research and Technology (CP Road Map), a national research plan developed and jointly implemented by the concrete pavement stakeholder community.

Moving Advancements into Practice (MAP) Brief

• The March 2014 MAP brief discusses mixture design and proportioning for concrete pavements.

News from the Road

• A recent FHWA report identified slab size as a key element in thin overlay failures.
• In a recent project, Minnesota researchers developed an improved design process for unbonded concrete overlays.
• A recent project funded by FHWA investigated accelerated test methods for determining alkalai-silica reaction.
• The US DOT recently completed a research project that evaluated high-volume fly ash concrete.
• Researchers in Texas recently investigated the use of manufactured sand in concrete pavements.

Updates from the States: Michigan

• Ongoing and completed research in Michigan is addressing research needs outlined by the CP Road Map.
