5.11 Environmental chambers which can maintain specified curing temperatures and humidity conditions. 5.12 Forced air draft ovens for curing long term evaluation specimens at 140°F +/- 3°F (60°C +/- 3°C.). 6.0 MATERIALS 6.1 Aggregates: Sample representative portions of aggregates used for slurry seal mix or micro-surfacing mix. Use material of the type, grade, and source proposed for the project. Use the aggregates that pass the 3.8 inches (96.5 mm) sieve. Aggregates shall be dried at 140°F (60°C) to a constant mass and cooled to the prescribed test temperatures prior to performing the test. 6.2 Asphalt emulsion shall be representative of the material to be used in the project. 6.3 Set control additives, both solid and liquid, shall be representative of the materials to be used in the project. 6.4 Distilled potable water with a pH between 6.0 and 7.0 shall be used. 7.0 EVALUATION PARAMETERS 7.1 Curing duration of specimens: 30 minutes, 1 hour, and 3 hours. 7.2 Curing temperatures of specimens: 59°F (15°C), 77°F (25°C), and 95°F (35°C). 7.3 Curing humidity of specimens: 50% and 90%. 8.0 PREPARATION OF TEST SPECIMEN 8.1 Aggregate, asphalt emulsion, set control additives and mixing water shall be maintained at 77°F (25°C). 115
8.2 The amounts of material components will be quantified as described by the mix design or through determinations from pre-testing using the Automated Mixing Test method. 8.3 Split or quarter a sufficient amount of the dried aggregate to obtain in one quarter 1300g to 1400 g, depending on the aggregate specific gravity and maximum nominal size. 8.4 Brush about 5g of tack coat emulsion (use the same emulsion as is used in the mixture) onto the casting plate so it is evenly covered. See Figure B.3. Allow to dry completely. Figure B.3: Applying Tack Coat 8.5 Center the specimen casting mold over the casting plate with tack coat as in Figure B.4.
