COMPACTION TESTING

The main problems involved in compaction control in the field are felt to be due to variability of soil types encountered on projects and in moisture control. The time taken in performing enough tests, and time restrictions in getting test results is also a problem. Sufficient test data can not be obtained on some projects prior to the application of the next lift of material due to time restraints and high contractor production rates. Also, on some base course and asphalt recycling projects, the nature of contaminated or oversize soils does not allow conventional compaction control procedures to be carried out. It is felt that the use of a clegg impact tester on projects would aid greatly in the accept-reject decision process. With sufficient experience and confidence gained in the use of this equipment, it is felt that it may become a very useful tool both in compaction evaluation and as a strength measuring tool.
