NOTE #1. Stone Coating Test. Use AASHTO T 59, Coating Test, except the mixture of stone and asphalt emulsion shall be mixed vigorously for five minutes and then immediately drenched with approximately twice its own volume of tap water at room temperature after which the aggregate shall be at least 90 percent coated with an asphalt film. NOTE #2. Modified Sand Coating Test. Use AASHTO T 59, Coating Test, except a mixture of air-dry test aggregate and asphalt emulsion shall be mixed thoroughly for five minutes then allowed to stand for five hours, after which the mixture shall be capable of being mixed for an additional five minutes. The mixture shall then be drenched with approximately twice its own volume of tap water at room temperature without showing more than 10 percent loss of bituminous film. The test aggregate for use in this test shall be a combination of 90 percent concrete sand and 10 percent Portland cement. The amount of asphalt emulsion used shall be 10 percent by weight {mass} of the aggregate. NOTE #3. Float Test. Use AASHTO T 50, with the exception that the residue shall be allowed to cool to room temperature and re-melted at lowest possible temperature that will bring it to a sufficiently fluid condition for easy pouring. Then pour into the collar for completion of the float test. NOTE #4. Viscosity Test. If the Viscosity Test begins to drip at 122 °F {50 °C} test temperature, the test shall be repeated at 160 °F {70 °C}. The Viscosity at 160 °F {70 °C} shall not exceed 200 seconds.

806.01Mineral Admixtures

The Department has established a list of Mineral Admixtures For Use In Portland Cement Concrete. These products can be found on List I-3 of the Department’s "Materials, Sources, and Devices With Special Acceptance Requirements" Manual. Refer to Subarticle 106.01(f) and ALDOT-355 concerning this list.

Fly ash shall consist of the finely divided residue or ash that remains after burning finely pulverized coal at high temperatures and shall meet the requirements of AASHTO M 295.

Microsilica for use as a mineral admixture in Portland cement concrete shall meet the requirements of AASHTO M 307.

Ground granulated blast furnace slag for use as a mineral admixture in Portland cement concrete shall meet the requirements of AASHTO M 302, Grade 100 or 120. The total cementitious material (the ground granulated blast furnace slag and the cement) shall meet the total alkali content requirement in Article 815.07. Additional requirements are given in Section 501. If ground granulated blast furnace slag is used as a mineral admixture in soil-cement stabilization, the ground granulated blast furnace slag shall meet the requirements of AASHTO M 302, Grade 100 or 120, and the content shall be 50 % of the weight {mass} of the total cementitious material.
