Abstract:Construction of portland cement concrete pavements is a complex process. A small fraction of the concrete pavements constructed in the
United States over the last few decades have either failed prematurely or exhibited moderate to severe distress. In an effort to prevent
future premature failures, 17 state transportation agencies pooled their resources, and a pooled fund research project, Material and
Construction Optimization for Prevention of Premature Pavement Distress in PCC Pavements, was undertaken in 2003. Its purpose was
to evaluate existing quality control tests, and then select and advance the state-of-the-practice of those tests most useful for optimizing
concrete pavements during mix design, mix verification, and construction. This testing guide is one product of that project. The guide
provides three recommended testing schemes (Levels A, B, and C, depending on a pavement’s design life and traffic volumes, etc.) that
balance the costs of testing with the risk of failure for various project types. The recommended tests are all part of a comprehensive suite
of tests described in detail in this guide.
