IP 549: Bitumen and bituminous binders - Measurement of density and specific gravity - Capillary-stoppered pyknometer method

Overview:

Scope

This European standard specifies a procedure for determining the specific gravity and density of bituminous binders at (25,0 ± 0,2) °C using the capillary-stoppered pyknometer method. Emulsions are excluded from the scope of this method.

NOTE 1 This method can also be used for other hydrocarbon binders, for bituminous binders from other sources, e.g. recovered from asphalt or after hardening and for bituminous binders containing filler. However, a lower precision is to be expected.

NOTE 2 This test method may be performed at other temperatures (i.e. 15 °C). When doing so, the density values of water and isopropanol should be determined.

The pyknometer method shall be used as a reference method for determining the specific gravity and density
of bituminous binders.
