DENSITY STANDARDS FOR FIELD COMPACTION OF GRANULAR BASES AND SUBBASES

This report presents the findings of a study to evaluate current procedures and criteria for the setting of density standards to control compaction during construction of granular base and subbase courses, and to develop more appropriate procedures and criteria. An extensive laboratory test program was carried out, comprising seven methods of compaction and four materials under various moisture conditions and gradations. The aggregates tested were a granite-gneiss a crushed gravel, a dolomitic limestone, and a basalt. A prototype field compact testing program was conducted using the same four aggregates. Procedures and criteria are proposed for use by highway agencies. /Author/
