Abstract
This report gives the results of a two-phased research program sponsored jointly by the National Roof­ing Contractors's Association and the Trumbull Division of the Owens-Corning Fiberglas Corporation. The primary objective was to study the relationship among application temperature, asphalt viscosity and the in­terply quality of asphalt used in the construction of built-up roof membranes. Phase I addressed hand-mop­ping and mechanical-spreader applications under controlled ambient conditions in Summit, Illinois. Phase II was conducted under actual on-the-roof ambient conditions on industrial buildings located in Tulsa, Okla­homa, and Lyman, South Carolina. The complete and detailed reports of the two phases are included as At­tachment I and Attachment II of this report. Each report contains: (1) Description of Tests; (2) Test results including Tables and Figures; (3) Conclusions; and (4) Recommendations.
