This standard 21/30423946 DC BS EN 17643. Bitumen and bituminous binders. Determination of equi-shear modulus temperature using a Dynamic Shear Rheometer (DSR). BTSV test is classified in these ICS categories:

• 91.100.50 Binders. Sealing materials
• 75.140 Waxes, bituminous materials and other petroleum products

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 quickly characterize bitumen and bituminous binders and to assess the deformation behaviour at high service temperatures. This document deals with the testing of fresh paving grade bitumen and modified bitumen, as conditioned in a laboratory ageing procedure (e.g. EN 12607 1, EN 14769) and also as 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.
