适用范围：This European Standard specifies an accelerated ageing/conditioning procedure for bitumen, bituminousbinders and bituminous mastics. The procedure involves rotating cylinder ageing (RCA), i.e binder ageing atmoderate temperatures in a large cylinder rotating in an oven under oxygen flow conditions. Prior to long-termageing with this method, samples are prepared in the condition they would be applied to the road.This method is also applicable to modified binders and bituminous mastics.NOTE For binders used in hot asphalt applications pre-conditioning of the sample would typically be by one of themethods given in EN 12607-1 or EN 12607-2 or directly in the RCAT cylinder to an equivalent ageing level. For bindersused in bituminous emulsion and cut-back application, stabilising the sample would typically be by methods given in EN14895. For bituminous emulsion, stabilising the sample can also be realised directly in the RCAT cylinder under a nitrogenflow (quantity-temperature-time have still to be experienced).WARNING — Use of this document can involve hazardous materials, operations and equipment, inparticular, the use of a flow of oxygen as ageing atmosphere. This document does not purport toaddress all of the safety problems associated with its use. It is the responsibility of the user of thisdocument to establish appropriate health and safety practices and determine the applicability ofregulatory limitations prior to use.If there is a likelihood that more than 1 % mass fraction in a binder of volatile components is present,this procedure must not be used.
