As part of a study called Material and Construction Optimization for Prevention of Premature Pavement Distress in PCC Pavements (MCO Project), researchers are evaluating conventional and new technologies to help state departments of transportation prevent premature distress in concrete pavements. This article provides an overview of the MCO Project. The 5-year pooled fund study was launched in 2003 by the Federal Highway Administration, Iowa State University and other partners. The study consists of three phases. In Phase I, now complete, researchers collected data, developed testing procedures and implemented pilot projects. In Phase 2, currently underway, researchers are further developing the test procedures and conducting field demonstration projects. Phase 2 is expected to being in 2006, when researchers will focus on technology transfer and helping states implement successful testing programs. A mobile concrete lab has been an important component in the MCO project for facilitating field testing.
