If there is any doubt without submerging the top of the flask. Measure and record as to whether the mix has absorbed water, proceed with this the temperature of the water in the flask. Remove the ther- procedure in order to determine if this correction is needed. The cover a flat tray with a nonabsorptive surface and place in front of a plate shall be the same one used during the calibration of the fan to remove surface moisture.

Standard Test Method for Theoretical Maximum Specific Gravity and Density of Asphalt Mixtures

Break agglomerations of flask. Wipe any moisture from the exterior of the container and mixture by hand. Stir the sample intermittently in such a way cover plate. Determine the mass of the flask, plate, and its that the aggregate particles are rolled over rather than simply contents completely filled with water. Designate this mass as E.

This process takes about 2 h. Take care to prevent the loss of particles of mixture. Calculation When Report where: The figures given Section A in Column 3 are the limits that should not be exceeded by the Single-operator precision 0.

Multilaboratory precision 0. When more than two results are being evaluated, the for Bowl Method only :B range given in Column 3 must be increased. Multiply the Single-operator precision 0.

A Basis of estimate: analysis of paired test results from to laboratories Example for three tests: 0. Additional guidance and background is given in Practice B Basis of estimate: 2 replicates, 7 materials, 20 laboratories.

NOTE 1—The transparent cover allows observation of the release of air bubbles. If underwater measurements will be taken, then the balance shall be equipped with a suitable suspension apparatus and holder to permit weighing the sample while suspended from the center of the scale.

To avoid damage, the manometer or gage itself is not to be situated on top of the vessel but adjacent to it. NOTE 2—Residual pressure in the vacuum vessel in millimetres of mercury is the difference in the height of mercury.

This device can be connected directly to the vacuum source or be in the vacuum line close to the source. NOTE 3—The vacuum leg of a residual pressure manometer occasion- ally acquires one or more air bubbles that introduce error into the residual pressure reading.Repeat this procedure a second time by removing the lid and placing both Wipe any moisture from the exterior of the container and cover plate.
