Determining In-Place Density (08/13/25)

Title: Determining In-Place Density
Speaker: Brandon Lima, Bituminous Mixture & Binder Supervising Technician, HDOT

This session will provide a detailed overview of the primary methods for measuring asphalt pavement density: core sampling, nuclear gauge testing, and non-nuclear gauge testing. While standardized procedures aim to ensure consistency, identical results across different labs or devices are not guaranteed—even when the same methodology is followed. This presentation will examine the factors that contribute to variability and offer insights into interpreting and reconciling density measurements in the field and lab.
