What it is
The conditioned sample is compressed to the specified condition and its recovery is measured after load removal.
Public test guide
Bitumen-rubber compression recovery
Measures how a bitumen-rubber specimen recovers after being compressed.
Plain-language explanation
What the test tells you.
The project specification controls the exact method and acceptance requirement.
What is used
Prepared blend specimen, temperature control, compression apparatus and dimensional measurement.
What it determines
Percentage or amount of recovery after the specified compression cycle.
Why it matters
Assesses elastic response and consistency of bitumen-rubber material.
Typical test sequence
From sample
to result.
- 01
Prepare and condition the specimen
- 02
Compress it according to the method
- 03
Remove load, allow recovery and calculate the result
