FIELD EVALUATION OF A NEW COMPACTION MONITORING DEVICE

This report documents a research project conducted to verify the effectiveness of the Soil Compaction Supervisor (SCS) as a tool for determining optimum compaction for highway construction applications. The scope of work included testing a number of different materials in a large test frame in a laboratory setting, as well as field testing at several highway construction sites throughout New England. The overall results of this study indicate that the SCS performs well as a quality assurance/quality control (QA/QC) tool for monitoring compaction of a wide variety of soils, provided that the specifications require a minimum of 95% compaction based upon standard Proctor density (AASHTO T-99, with coarse particle correction). In addition to testing a wide range of soils, use of the SCS with lightweight aggregate and asphalt was also investigated. It was concluded that the SCS is not a viable QA/QC tool for use with lightweight aggregate. A limited amount of testing performed on asphalt indicates that, although the SCS could potentially be used to monitor compaction of that material, it might produce a "stop compaction" signal prematurely in that application. It might be necessary for the manufacturer to make adjustment(s) to the internal data processing in the SCS meter if it is to be used for monitoring asphalt compaction where specifications require a minimum of 98% compaction.
