Bituminous mixtures. Test methods for hot mix asphalt - Determination of bulk density of bituminous specimens by gamma rays
What is BS EN 12697-7 - bulk density of bituminous specimens by gamma rays about?
Knowing the density of bitumen helps you to assess the strength and durability of the paving. BS EN 12697-7 is the seventh part of the ‘bituminous mixtures – Test methods for hot mix asphalt’ multi-series. BS EN 12697-7 specifies a method for measuring the bulk density of pavement mixtures using a transmission-type gamma radiation test bench. The applicability of BS EN 12697-7 is described in the product standards for bituminous mixtures. The safety regulations applicable to the use of gamma rays should be applied. BS EN 12697-7 applies to cylindrical specimens or blocks, prepared in a laboratory or cut from the pavement, the thickness and the mass absorption coefficient which is a function of the chemical composition are known.
