Description
This report analyzes the Quality Control/Quality Assurance (QC/QA) data for Portland cement concrete pavement (PCCP) awarded in the years 2000 through 2009. Analysis of the overall performance of the projects is accomplished by reviewing the Calculated Pay Factor Composite (CPFC) and Incentive/Disincentive Payments (I/DP). Analysis of each of the test elements: thickness, compressive strength, sand equivalent, and flexural strength is also completed....
