Improvement and Validation of Mn/DOT DCP Specifications for Aggregate Base Materials and Select GranularStatus: CompleteReport Date: 12/31/2005 Summary: Eleven construction projects from around the state were selected for testing during the summer of 2003. At each construction project, several locations were randomly selected for testing. At each location, various devices were used to obtain in-situ stiffness, strength, density and moisture data. In addition, samples were also taken for gradation and Proctor tests from the majority of the test locations. The materials included Select Granular, CL3, CL5, CL6, CL7 and full-depth reclamation. The proposed DCP specification from 2002 testing was validated and modified using the 2003 data. Final Deliverables: Improvement and Validation of Mn/DOT DCP Specifications for Aggregate Base Materials and Select Granular (Report #2005-32) Related Materials: Related Research:
