How to Perform Ductility Test in ASTM D113 Standards?
Purpose of Ductility Test:
• The shrinkage and elongation of bitumen is called ductility. The ductility test is carried out to determine the elongation ability of bitumen under slow acting loads. The amount that the sample prepared in accordance with the standards can stretch without breaking is determined in cm.
Equipments to be Used in the Ductility Experiment:
• 3 Ductility Patterns.
How to Ductility Experiment:
• The sample is heated not to exceed 90°C above the softening point temperature and poured into ductility molds. 3 samples are prepared.
• After the samples are kept at room temperature for 30 minutes to cool, they are kept in a water bath at 25°C for another 30 minutes.
• The samples removed from the bath are placed in the ductility device at their perforated ends and the device is operated. The drawing process is continued until the samples break.
• The ductility device works at a speed of 5 cm/min.
Result:
• At the time of bitumen rupture, the elongation amount is read in cm from the ruler on the device. This value indicates the binding performance of the bitumen. Bitumen with high ductility value also has high binding properties.
