• Abstract:
  Concrete has traditionally been accepted by testing air, slump, and strength. However, these test methods usually do not have a direct relationship with long term durability. A number of new test methods have been developed that give a better prediction of long-term performance. On a recent paving project on US 20 in Woodbury County, Iowa, several of the new test methods were evaluated to gain experience with the test methods and determine viability of using test methods for quality control and acceptance. The contractor performed quality control (QC) shadow testing using the SAM air meter test for air and freeze thaw potential, box test for workability, and resistivity testing for fluid transport properties. The Federal Highway Administration (FHWA) Mobile Concrete Laboratory was also on the project collecting data for the PEM pooled fund project. Results indicated the new test methods are repeatable and provide valuable information on long term performance potential for concrete pavements.
