PHASE II REPORT - Caltrans

9.2 Completely cover the specimen with water at the specified temperature so that
there is approximately 0.11-0.15 inches (2.8 – 3.8 mm) of water over the surface of the test
specimen. Soak for 1 minute.
9.3 Lift the mounting plate until the surface of the specimen comes in contact with the
abrading wheels.
9.4 Switch to the low speed of the Hobart machine. Abrade for 60 seconds.
9.5 Lower the mounting plate and remove the specimen plate with the aid of a plate
removal device. Carefully rinse the loose debris with 1000 ml to 1500 ml of water. Carefully dry
the specimen and casting plate with an absorbent paper towel. Record the final weight.
