註釋An investigation of the feasibility of establishing density proctors for mine sources providing pavement base materials to FDOT projects was conducted. Research procedure involved statistical analysis of test data from 69 mines for the period 1999-2004. Additionally, field densities and field laboratory proctor densities were compared to mine test values. Procedures for offering an option to utilize previously established mine proctor in lieu of laboratory proctor testing of project delivered material was suggested. The proposed alternative would eliminate the 4 to 5 day waiting time for laboratory proctor results.
