Anotácia

This practice describes the standard procedure for sampling, analysis, and removal of specimens in built-up bituminous roof systems during application, but before the application of flood coating and top surfacing, for determining the approximate quantities of the components and the possible presence of moisture, or dry spots between plies, in the field. These components may be composed of insulation (when part of the roof membrane system), plies of roofing felt, interply layers of bituminous material, and top coating (if present, before any surfacing aggregate has been applied). Appropriate calculation procedures are also indicated herein.
