Development of New Test Methods for Determining Relative Compaction of Untreatedand Treated Soils and Aggregates

摘要

The report presents new and revised test methods for relative compaction of soilsand aggregates. The existing test methods and their development are reviewed. This includes a detailed discussion of the 'wet' method concept and how it is used to determine relative compaction. A mathematical proof verifying the 'wet' method is presented. New California Test Method (CTM) 122 and revisions to current tests, CTM 216 and CTM 231 are presented, in order to reduce redundancies in the tests and improve understanding of how they determine relative compaction. Procedures are developed to allow the use of modified Proctor compaction equipment in conjunction with the 'wet' method concept as a test alternative.
