Standard Method of Test for Density of In-Place Hot Mix Asphalt (HMA) Pavement by Electronic Surface Contact Devices American Association of State and Highway Transportation Officials / 2012 / 5 pages

More details

More info

This method covers the in-place determination of the total density and relative compaction of HMA pavements by measuring changes in the electromagnetic field resulting from the compaction process.

The equipment referenced in this method is a surface contact device that is relatively unaffected by the surface moisture and surface variances in temperature typically encountered during HMA paving operations. If needed, it should include circuitry to measure/compensate for moisture and temperature variances during the material compaction process.
