[Current]Methods of sampling and testing asphalt, Method 14.1.1: Field density tests — Determination of field density of compacted asphalt using a nuclear surface moisture-density gauge — Direct transmission mode
This Standard sets out the method for determining the field density of asphalt using a nuclear surface moisture-density gauge in the direct transmission mode of operation. The method is applicable to asphalt layers equal to or greater than 75 mm in thickness, and to asphalts having a nominal maximum size not greater than 40 mm.
