Asphalt Ductility Test Equipment: Testers, Molds & Accessories

Choose the Tester for the Binder Procedure

Asphalt ductility testing measures binder elongation before failure in a liquid-filled trough at controlled temperature and speed. Select the tester for the governing procedure, including required temperature range, travel speed and the number of simultaneous specimens. Ductility testing is a binder characterization test, distinct from mixture stability or pavement fieldwork.

The Temperature-Controlled Ductility Tester is the listed configuration. Verify its specifications—temperature range, stroke length, travel speed and force capacity—against your procedure rather than assuming all ductility testers share the same arrangement.

Match Molds and Base Plates

Ductility briquette molds and base plates are required for specimen preparation and are sold separately from the tester. Confirm the mold type required by your method before ordering.

Listed options include Standard Ductility Molds and Force Ductility Molds, with matching standard and large base plates. Standard and force ductility are different procedures; match each mold and plate to the intended test rather than treating them as interchangeable accessories.

Consider Force Ductility and Related Binder Tests

Force ductility arrangements measure tensile force during elongation alongside ductility. Confirm the required measurement, force range and documentation for this configuration before selecting molds and recording equipment; not every ductility procedure requires force measurement.

The Softening Point Ring and Ball Apparatus measures a different binder property and is not a substitute for a ductility tester. Keep each binder characterization method's equipment separate, and confirm accessory compatibility within the ductility family only.

Plan Temperature Control and Installation

Review the tester's heating and cooling arrangement, water-bath volume and digital controller against your laboratory's power supply and required test temperatures. Confirm drain, fill and maintenance arrangements using the manufacturer's instructions.

Check bench or floor space for the trough's length, loading access and specimen transfer workflow. For other binder characterization equipment, compare asphalt penetration test equipment and asphalt viscosity testing equipment; their accessories are not interchangeable with ductility molds and plates.
