Bituminous mixtures - Test methods for hot mix asphalt - Part 45: Saturation Ageing Tensile Stiffness (SATS) Conditioning Test prEN 12697-45

Scope

This European Standard describes a test method to assess the durability of adhesion in base and binder course asphalt mixtures using the Saturation Ageing Tensile Stiffness (SATS) conditioning regime, to age the specimens in the presence of water, together with a comparative test for assessing performance before and after conditioning. The applicability of this test method is limited to bituminous specimens with consistent air voids contents and hard binder grades. The test is intended to be used as an initial type test for assessment of a combination of aggregate, filler and additives.
