DIN EN 12697-26:2012-06

This European Standard specifies the methods for characterising the stiffness of bituminous mixtures by various tests, including bending tests and direct and indirect tensile tests. The tests are performed on compacted bituminous material under a sinusoidal loading or other controlled loading, using different types of specimens and supports. The procedure is used to rank bituminous mixtures on the basis of its stiffness, as a guide to relative performance in the pavement, to obtain data for estimating the structural behaviour in the road and to judge test data according to specifications for bituminous mixtures. As this standard does not impose a particular type of testing device the precise choice of the test conditions depends on the possibilities and the working range of the device used in the particular case. For the choice of the respective test conditions, the requirements of the product standards for bituminous mixtures should be respected. The applicability of this document is described in the product standards for bituminous mixtures. The committee responsible for this standard is NA 005-10-10 AA "Asphalt (SpA zu CEN/TC 227/WG 11) Gemeinschaftsausschuss mit FGSV" ("Bituminous mixtures (Mirror Committee of CEN/TC 227/WG 11) Joint committee with FGSV") at DIN.
