ASTM D6935-11
(Test Method)Standard Test Method for Determining Cement Mixing of Emulsified Asphalt
Standard Test Method for Determining Cement Mixing of Emulsified Asphalt
SIGNIFICANCE AND USE
The result of this test method indicates the ability of a slow setting emulsified asphalt to mix with a finely divided, high surface area material (high early strength, Type III, portland cement) without breaking the emulsified asphalt.
SCOPE
1.1 This test method is intended to be a mixing test used to identify or classify a slow setting, SS or CSS, type of emulsified asphalt.
1.2 This test method does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
