Research Project Capsule

Louisiana Transportation Research Center's (LTRC’s) Geotechnical and Asphalt groups will be conducting two separate field and laboratory evaluations. The Geotechnical group will evaluate field densities of soil layers and the Asphalt group will evaluate field densities on asphalt pavement layers. There are two overall objectives of this research, to conduct a validation study to compare the new Troxler and TransTech gauges against the original nuclear moisture-density gauge, and to evaluate the nuclear and non/low-nuclear gauge as quality assurance (QA) devices for non-destructive density. Additionally, the research will utilize intensive field tests and core samples to determine their effectiveness, benefits, and implementation potential for QA/quality control (QC) applications within the Louisiana Department of Transportation and Development (LADOTD).
