What it is
A standard briquette is pulled apart at a specified temperature and speed.
Public test guide
Bitumen ductility
Measures how far a shaped bitumen specimen can stretch before breaking under controlled conditions.
Plain-language explanation
What the test tells you.
The project specification controls the exact method and acceptance requirement.
What is used
Binder briquette mould, temperature-controlled ductility bath and pulling mechanism.
What it determines
Elongation at break under the test conditions.
Why it matters
Provides an indication of binder extensibility and supports specification or comparison of binder behaviour.
Typical test sequence
From sample
to result.
- 01
Prepare and condition the standard binder briquette
- 02
Pull it at the specified speed and temperature
- 03
Record elongation when the thread breaks
