    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.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 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 in accordance with Specification D226/D226M; fabrics in accordance with Specification D173/D173M or D1668/D1668M (asphalt types); asphalt-impregnated glass mat in accordance with Specification D2178/D2178M; and with primer in accordance with Specification D41/D41M.

    1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system should be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
