Investigation of Electromagnetic Gauges for Determination of In-Place Density of HMA Pavements, Phase II

Electromagnetic asphalt density gauges have the potential to facilitate more efficient quality control and quality assurance in Iowa. The objectives of this project are to: (1) Evaluate two electromagnetic gauges for their ability to determine the adjusted density (including corrections for surface moisture, temperature variation, and sensor impedance) of hot mix asphalt (HMA) pavements; (2) Determine whether the correction factor used for a specific mix on the first day of paving operations can be used on subsequent paving days under the same conditions; and (3) Determine the most suitable adjustment method for determining pavement density.
