This document specifies the Binder Fast Characterization Test (for short: BTSV test, German: Bitumen-Typisierungs-Schnell-Verfahren). The test is conducted using a Dynamic Shear Rheometer (DSR). It is used to characterize bitumen and bituminous binders and to assess the deformation behaviour at high service temperatures. The test procedure described in this document covers the testing of paving grade bitumen or modified bitumen, as fresh (unused) binders, as well as binders after laboratory ageing conditioning (e.g. EN 12607-1, EN 14769), and also binders that have been recovered from asphalt mixtures. The test procedure in accordance with this document is not applicable for bituminous binders with particles larger than 250 μm (e.g. filler material, granulated rubber). NOTE The test procedure has not been applied on bituminous binders recovered from bitumen emulsions yet. The test determines the temperature and the associated phase angle at which a bituminous binder exhibits a defined complex shear modulus in stress-controlled oscillation mode at constant frequency and with continuous increase of the test temperature. WARNING – The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to ensure that regulatory requirements are fulfilled prior to application of this document. This document involves handling of apparatus and binders at very high temperatures. Always wear protective gloves and eyewear when handling hot binders, and avoid contact with any exposed, unprotected skin.
