Bituminous Mixtures - Test Methods - Part 45: Saturation Ageing Tensile Stiffness (SATS) Conditioning Test
Also Known As:
The DIN EN 12697-45 standard describes a test method used to evaluate the durability of adhesion in base and binder course asphalt mixtures. The test involves subjecting the specimens to a Saturation Ageing Tensile Stiffness (SATS) conditioning regime, where they are aged in the presence of water. The purpose of this test is to assess the performance of the specimens before and after conditioning, allowing for a comparison of their adhesion properties.
It is important to note that this test method is applicable only to bituminous specimens with consistent air voids contents and a hard binder, specifically asphalt concrete mixtures with a binder content ranging from 3.5% to 5.5%, air voids contents between 6% and 10%, and 10/20 pen hard paving grade bitumen. The SATS conditioning test is primarily used as a screening test to evaluate the adhesion properties of a combination of aggregate, filler, and additives after simulated ageing in a moist atmosphere for lean/stiff base and binder course mixtures.
The standard also mentions that alternative conditions for mixtures with different binders or other situations not covered by this European standard are currently being developed, suggesting that this test method is subject to further improvement and expansion in its applicability.
