Abstract

Abstract : Analysis of the data on reduced Proctor and standard Proctor test results collected from literature indicate that it is possible to replace the standard Proctor test with reduced Proctor test owing to the advantages that reduced Proctor test requires 40% less compaction energy, requires no modifications to the standard Proctor compaction apparatus unlike other small compaction tests, and the soil particle size requirements remain the same as that of standard Proctor test. Correlations have been developed for compaction characteristics between modified Proctor and reduced Proctor, to estimate compaction characteristics at modified Proctor energy level by just performing reduced Proctor test. Optimum moisture content was found to correlate well with liquid limit. Also, the maximum dry density bears a very good correlation with optimum moisture content for the reduced Proctor test.
