The Saturation

37、Ageing Tensile Stiffness (SATS) conditioning regime is used to age the specimens in the presence of water. A comparative test for assessing their performance before and after conditioning is also conducted. The applicability of this test method is limited to bituminous specimens with consistent air

38、voids contents and hard binder, in particular, to asphalt concrete mixtures with a binder content between 3,5 % and 5,5 %, air voids contents between 6 % and 10 % and 10/20 pen hard paving grade bitumen. The test is intended to be used as a screening test for the assessment of a combination of aggre

39、gate, filler and additives with respect to the retained adhesion properties after simulated ageing in a moist atmosphere for lean/stiff base and binder course mixtures. NOTE Alternative conditions for mixtures with binders other than 10/20 hard grade bitumen or other situations not covered by this E

They are then transferred into a pressurised vessel partially filled with water where they are subjected to a conditioning procedure by storage at 85 C temperature and 2,1 MPa pressure for 65 h. The ratios of the stiffness, measured by indirect tension on cylindrical specimens, before and after conditioning by storage under increased pressure and elevated temperature on the individual specimens situated above the water are averaged to determin
