Abstract
This report describes the initial construction phase of a projected two-year evaluatuion of sheet-applied elastomeric ethylene propylene diene monomer (EPDM) roofs and liquid-applied elastomeric coating on sprayed polyurethane foam (PUF) roofs. This work is part of a research effort being conducted by the U.S. Army Construction Engineering Research Lab (CERL) to attempt to identify alternative, easy-to-install roofing systems that can improve the performance of Army roofing while reducing life-cycle costs. Sprayed PUF roofs coated with sprayed elastomeric material were installed on buildings at Ft. Benning, Ga.; Ft. Knox, Ky.; and Ft. Lewis, Wash. Sheets of EPDM synthetic rubber were installed on buidings at Ft. Benning and Ft. Lewis. Built-up roofing systems were installed on buildings at Ft. Benning and Ft. Lewis for control purposes. Thermocouples were installed below the insulation on all roofs, and thermocouples and strain gauges were installed above the membrane on the EPDM roofs at Ft. Benning and Ft. Lewis so that a continuous record could be obtained of heat flows and membrane movement. Samples will be taken from all roofs every six months for two years for lab testing, and the roofs will be visually inspected every year for 10 years. Weather-recording stations were installed at Ft. Benning and Ft. Lewis so that roof temperatures and movements could be coordinated with ambient conditions.
