摘要：	There has been increasing interest in ensuring new asphalt materials are constructed so that they will be durable, and tests such as the Saturated Ageing Tensile Stiffness (SATS) test have been developed for that purpose. However, there is also often a need to assess the remaining service life of existing asphalt layers. To investigate this aspect, trials have been undertaken to see if the SATS test, or a modification thereof, could be used to obtain such information from cored samples. Tests using the current SATS protocol and two variants of it have been undertaken on cores from RAF runways and taxiways. The tests have shown that some discrimination may be possible, supported by results from other, simpler, tests also indicating that the material was suspect, at least for the particular layer that was known to be imperfect.
