6、 1.6. Performance Requirements6.1 UniformityThe emulsion shall be homogeneous. Aftera thoroughly stirred sample has been held at 10C (50F) in aclosed container for 48 h, there shall be no separation of water,coagulation of the asphalt base, settling, or packing in thecontainer that cannot be overcom

7、e by moderate hand stirring.6.2 ConsistencyThe emulsion shall be of a consistencythat will spread readily and permit application by brush, mop,or trowel at the rate of 1.0 L/m2(2.5 gal U.S./100 ft2)tovertical metal surfaces at ambient temperatures above 10C(50F). See Section 17 of Test Methods D 293

8、9.6.3 StabilityThere shall be no coagulation during thecement addition or at the conclusion of the 1-min mixingperiod.6.4 The emulsion shall conform to the additional require-ments prescribed in Table 2.7. Sampling and Test Methods7.1 Sample the material, and determine the properties enu-merated in

10、.7.2.2 Procedure:7.2.2.1 Place about 200 g of emulsion in a tared 500-mLround-bottom porcelain dish, and weigh.7.2.2.2 Add 25 mass % portland cement based on theweight of the emulsion, in small portions while stirringconstantly with a stiff spatula.7.2.2.3 Add small amounts of distilled water if the

11、 mixturebecomes too stiff to be workable.7.2.2.4 After addition of all the cement, stir the mixturethoroughly for 1 min.7.2.2.5 Watch for any sign of coagulation of the asphalt baseduring addition of the portland cement and after the 1-minstirring period.1This specification is under the jurisdiction
