Scope1.1 This specification covers three types of asphalt suitablefor use as a mopping coat in dampproofing; or as a plying ormopping cement in the construction of membrane waterproof-ing systems with felts in accordance with Specification D226;fabrics in accordanc
4、e with Specifications D173 or D1668(asphalt types); asphalt-impregnated glass mat in accordancewith Specifications D2178; and with primer in accordance withSpecification D41.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineac
