Laboratory Dielectric Measurement System (LDMS) for Asphalt Mixture Bulk Specific Gravity Determination

Bulk specific gravity is measured routinely during mixture design and quality assurance processes for asphalt mixtures. Due to a variety of factors, there can be large measurement variability that may require repeated measurements.

The TRB IDEA (Innovations Deserving Exploratory Analysis) Program's NCHRP IDEA Final Report for Project 229: Laboratory Dielectric Measurement System (LDMS) for Asphalt Mixture Bulk Specific Gravity Determination seeks to establish both the reliability and standardizing procedure for the LDMS and the relationship between dielectric value and bulk specific gravity.
