Bituminous mixtures - Test methods - Part 3: Bitumen recovery: Rotary evaporator
This document describes a test method for the recovery of soluble bitumen from bituminous mixtures used in road, airfield or similar pavements in a form suitable for further testing. The test can be undertaken on either loose or compacted asphalt materials. The procedure is suitable for the recovery of paving grade bitumens, for which materials this European Standard is the reference method. The fractionating column procedure (see EN 12697-4) is the reference method for mixtures containing volatile matter such as cut-back bitumen.
For recovery of polymer modified bitumens, the rotary evaporator procedure is recommended.

1 Modification to the Title
Replace the title:
“Bituminous mixtures - Test methods for hot mix asphalt - Part 3: Bitumen recovery: Rotary evaporator”
with:
“Bituminous mixtures - Test methods - Part 3: Bitumen recovery: Rotary evaporator”.
2 Modification to 5.1, Apparatus for the extraction of the soluble bitumen
Replace the NOTE with the following one:
“
NOTE The use of the hot extraction methods in EN 12697-1 may harden the binder and hence affect the
results from subsequent tests.”.
3 Modification to 7.1, Extraction of the bitumen and removal of insoluble matter
In the numbered entry 7.1.2, replace:
"
7.1.2 Allow the bitumen solution to stand for a minimum of 10 min, and pour out the bitumen
solution through a 0,063 mm sieve to remove any insoluble material. This can be achieved by either a)
or b)."
