ASTM D113 IP 32 (obs) DUCTILITY OF BITUMINOUS MATERIALS
This test method describes the procedure for determining the ductility of a bituminous material measured by the distance to which it will elongate before breaking when two ends of a briquet specimen of the material, of the form described in Section 4, are pulled apart at a specified speed and at a specified temperature. Unless otherwise specified, the test shall be made at a temperature of 25 ± 0.5°C and with a speed of 5 cm/min ±5.0%. At other temperatures the speed should be specified.
ASTM D6084 ELASTIC RECOVERY OF BITUMINOUS MATERIALS BY DUCTILOMETER
This test method covers the elastic recovery of a bituminous material measured by the recoverable strain determined after severing an elongated briquet specimen of the material of the form described in . The specimens are pulled to a specified distance at a specified speed and at a specified temperature. Unless otherwise specified, the test shall be made at a temperature of 25 0.5°C (77 0.9°F) and with a speed of 5 cm/min ±5%.
EN 13398 DETERMINATION OF THE ELASTIC RECOVERY OF MODIFIED BITUMEN
This standard specifies a method for the determination of the elastic recovery of bituminous binders in a ductilometer at a given temperature. It is especially applicable to bituminous binders modified with thermoplastic elastomers, but can also be used with other bituminous binders which generate only small recovery.
EN 13589 DETERMINATION OF THE TENSILE PROPERTIES OF MODIFIED BITUMEN BY THE FORCE DUCTILITY METHOD
This European Standard specifies a method for determining the tensile properties of a bituminous binder, in particular those of polymer-modified bitumens by means of a force ductility test.
