Abstract

This research identified key equipment-related factors associated with inconsistencies in test results obtained with different compaction and testing equipment. Several U.S. and Canadian private and public agencies regularly participate in round-robin or mix-exchange programs, which are discussed. To examine the ability to measure the fundamental process parameters of the Marshall compaction operation, several mix specimens were compacted with a mechanical hammer instrumented with accelerometers. From the analysis of data obtained, it was concluded that technology for measuring the amount of energy delivered to the specimen during the compaction process is currently available.
