Aggregate Gradation Control Program, Virginia

Report No: 85-R39

Published in 1985

About the report:

In 1983, Virginia implemented a specification for the acceptance of aggregate base and bituminous concrete in which the producer undertook the acceptance testing and state personnel did much reduced testing as a monitoring program. Although some people predicted that the quality of the materials being received by the state would drop drastically following the removal of state inspectors from the aggregate and asphalt plants, the program appears to be working well. The evolution in specifications that preceded the one on which this report is based should be considered by any agency contemplating a similar system.
