This specification covers emulsified asphalt suitable for use as a protective coating for built-up roofs and other exposed surfaces with specified inclines. The emulsified asphalts are grouped into three types, as follows: Type I, which contains fillers or fibers including asbestos; Type II, which contains fillers or fibers other than asbestos; and Type III, which do not contain any form of fibrous reinforcement. These types are further subdivided into two classes, as follows: Class 1, which is prepared with mineral colloid emulsifying agents; and Class 2, which is prepared with chemical emulsifying agents. Other than consistency and homogeneity of the final products, they shall also conform to specified physical property requirements such as weight, residue by evaporation, ash content of residue, water content flammability, firm set, flexibility, resistance to water, and behavior during heat and direct flame tests.
