| 摘要： | Because no systematic procedure exists to determine priorities and select repair strategies for low-slope roofs, the U.S. Army Construction Engineering Research Laboratory (USA-CERL) is developing a roof maintenance management system that will provide a practical decisionmaking procedure to identify cost-effective repairs. As part of the system for built-up roofs, this volume presents the standardized information needed to conduct the visual inspection survey, including names, descriptions, severity levels, measurement criteria, causes and photographs of membrane and flashing distresses. Procedures for distress density calculations are also provided. Roof inspectors can use this information to objectively determine the indexes that reflects the (1) ability of the membrane and flashing to perform their functions, (2) needed level of maintenance, and (3) waterproof integrity. Volume I describes the development and verification of the indexes. |
