Digital Ductility Meter: DDA 3
The automatic DDA 3 force-ductility meter offers three procedures to measure bitumen properties:
Ductility or elongation is measured by the distance to which a sample will elongate before breaking.
Elastic recovery is measured by the recoverable strain determined after severing an elongated briquette specimen. This is useful in confirming that a material has been added to the bitumen to provide a significant elastomeric characteristic.
Force-ductility measures tensile properties and the deformation energy.
