BS EN 12697-6-2020 Bituminous mixtures一Test methods Part 6: Determination of bulk density of bituminous specimens. 9.3 Procedure B: Bulk density — Saturated surface dry (SSD) Carry out the procedure as follows: a) Determine the mass of the dry specimen (mj. When testing damp specimens, step a) shall be carried out after steps b) to g). b) Determine the density of the water at test temperature to the nearest 0,000 1 Mg/rn3 (pw) according to 5.1. c) Immerse the specimen in the water-bath at known test temperature. Allow the water to saturate the specimen sufficiently long enough for the mass of the specimen not to change. In general, the required saturation period is 30 mm but should not be more than 3 h. d) Determine the mass of the saturated specimen when immersed (rn2), taking care no air bubbles adhere to the surface of the specimen or leave the specimen when weighing. e) Remove the specimen from the water, dry the surface from adhered drops by wiping with a damp Chamois. 0 If water continues to drain from the sample, discontinue the measurement by Procedure B, saturated surface dry, and undertake the measurement by Procedure C, sealed specimen or procedure D if applicable. g) Determine the mass of the saturated, surface wiped specimen in air immediately after drying (rn3). 9.4 Procedure C: Bulk Density — Sealed specimen Carry out the procedure as follows: a) Determine the mass of the dry specimen (mi). When testing damp specimens, step a) shall be carried out after steps b) to 1). b) Determine the density of the water at test temperature to the nearest 0000 I Mg/rn3 (p.) according to 5.1. c) Seal the specimen with material according to 5.2 in such a way, that the internal voids in the specimen being part of the volumetric material composition are not penetrated and that no extra voids are included between seal and specimen or in seal folds. After sealing, the specimen shall be Inaccessible to water when submerged. When using paraffin wax, obtain sealing using the following procedure: 1) Bring the paraffin wax to its melting temperature + 10 °C and maintain this temperature at ± 5 °C. 2) Immerse the specimen partially in the paraffin wax for less than 5 s, agitating the specimen to make the air balls free. After cooling and solidification of the paraffin wax on this part of the specimen, repeat...
