METHODS OF SAMPLING AND TESTING ASPHALT, METHOD 14.2: FIELD DENSITY TESTS - DETERMINATION OF FIELD DENSITY OF COMPACTED ASPHALT USING A NUCLEAR THIN-LAYER DENSITY GAUGE

This Standard sets out the method for determining the field density of thin layers of asphalt using a nuclear thin-layer density gauge with two backscatter modes of operation or geometries. The gauge simultaneously determines, by the independent backscatter geometries, two values of gross mass per unit volume. The density of the top layer of asphalt of selected thickness is estimated by mathematically eliminating the influence from the underlying layer(s). The method is applicable to asphalt layers between 25 mm and 100 mm thick and to asphalts having a nominal maximum size not greater than 40 mm. (a) The Standard was approved on behalf of the Council of Standards Australia on 12 February 1999 and on behalf of the Council of Standards New Zealand on 5 February 1999
