asphalt-Water displacement method.

8 VOlUME OF PYCON1ETER

The procedure to determine the volume of the pycnometer used in Procedure 9.2 shall he as follows:

(a) Weigh the pycnomctcr and lid and record the mass (m1).

(b) Fill the pycnometer with water from the water bath and place in the water bath.

(c) Leave the flask in the water bath until the water temperature in the flask and water bath are the same. Record the temperature of the water (ti).

(d) Top up the pycnometer with water from the water bath and slide on the lid ensuring that no air bubbles are trapped.

(e) If air bubbles are observed repeat Steps (C) and (d) until all air is eliminated.

(f) Carefully dry the outside of the pycnometer. Weigh the pycnometer, lid and water and record the mass (m2).

(g) Empty and dry the pycnometer.

NOTE: Step (a) to Step (f) of the procedure determine the volume of the flask at the test temperature (t1). Following an initial

determination, only periodic checks need be carried out—at least six monthly.
