(Guide)Standard Guide for Application of Asphalt-Based Protection Board
Standard Guide for Application of Asphalt-Based Protection Board
SIGNIFICANCE AND USE
4.1 This guide outlines general procedures for the storage and application of semi-rigid protection board to below-grade and below wearing surface waterproofing. The proper application is necessary to prevent damage to the waterproofing membrane during backfilling, paving, or other construction operations, as well as to minimize the effects of soil stresses.
4.2 This guide is intended to supplement instructions from designers and manufacturers.
SCOPE
1.1 This guide lists minimum application and installation requirements for semi-rigid protection board when used as protection for below-grade or below wearing surface (like plaza decks) waterproofing.
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 shall 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. For specific precautionary statements, see Section 8.
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.
