RAPID COMPACTION CONTROL TESTING USING WET METHOD

The California rapid wet weight method using the sand cone and nuclear gauge for determining the percentage of relative compaction is discussed. Oven drying operations, true density relationships, and optimum moisture determinations were eliminated. This permits test results to be available in a matter of hours instead of by the following day. The validity of the method was confirmed by mathematical calculations and by field correlation tests. Comparisons were made between the wet and the conventional dry method to obtain the percentage of relative compaction. This comparison was made by using the California nuclear procedure in which average test results are used. Using the wet method expedites construction testing in many cases by eliminating the need to determine test maximum density and optimum moisture. This is possible because test results are available as soon as a specimen is compacted and answers do not depend on overnight ovendry moistures. The application of the wet method to tests such as those of the American Society for Testing and Materials and the American Association of State Highway and Transportation Officials, in which fixed volume test molds are used, is demonstrated.
