【国外标准】 Standard Specification for Materials for Bridge Deck Waterproofing Membrane Systems

This specification covers three types of deck waterproofing membrane systems designed for use on bridge decks which will receive an asphaltic concrete overlay. Type I are cold liquid-applied chemically curing membrane materials that that require a membrane protection course. Type II, on the other hand, are hot applied elastomeric membrane systems that also require a membrane protection course. And finally, Type III are preformed sheet membrane systems. All types are applied to a bridge deck to prevent the passage of water from the bituminous surface course to or through the bridge deck. Membrane systems shall be sampled as appropriate for each type, and shall conform to performance requirements and physical properties as to permeability, and pliability.1.1 This specification covers deck waterproofing membrane systems designed for use on bridge decks which will receive an asphaltic concrete overlay.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.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.
