This specification covers three types of asphalt suitable for use as a mopping coat in dampproofing; or as a plying or mopping cement in the construction of membrane waterproofing systems with felts, fabrics, and asphalt-impregnated glass mat. Three types of asphalts have been designated: Type I is a soft, adhesive, “self-healing” asphalt that flows easily under the mop and is suitable for use below grade under uniformly moderate temperature conditions both during the process of installation and during service, Type II is a somewhat less susceptible asphalt than Type I, with good adhesive and “self-healing” properties, suitable for use above grade where it will not be exposed above a certain temperature, and Type III is an asphalt less susceptible to temperature than Type II, with good adhesive properties, and suitable for use above grade on vertical surfaces exposed to direct sunlight or above a certain temperature. The asphalt shall be prepared from crude petroleum by suitable refining processes to conform to the applicable physical requirements for each type. Different tests shall be conducted in order to determine the following physical properties of asphalt: softening point, flash point, penetration, ductility, and solubility in trichloroethylene.
