Abstract:

The U.S. Army Construction Engineering Research Laboratories (CERL) has recently completed a 10-year field exposure study of the performance of poly(vinyl chloride) (PVC) roofing membrane materials. The intent of the CERL study was to compare the results of laboratory tests of membrane properties with field performance. Periodically, over the 10 years, CERL visually inspected the roofs to evaluate their performance and removed samples for laboratory characterization of selected mechanical and physical properties. The National Institute of Standards and Technology (NIST) conducted statistical analysis of the 10-year data set. The paper summarizes the results of the field observations and analyses. Membranes from three manufacturers were installed at Chanute Air Force Base, Illinois, Dugway Proving Ground, Utah, and Fort Polk, Louisiana. A major difference in the roof constructions was that, atChanute, the membranes were ballasted, whereas at Dugway and Fort Polk, they were mechanically attached and adhered.
