Title: CONDITION EVALUATION OF CONCRETE BRIDGES RELATIVE TO REINFORCEMENT CORROSION. VOLUME 4: DECK MEMBRANE EFFECTIVENESS AND A METHOD FOR EVLUATING MEMBRANE INTEGRITY
Accession Number: 00624362
Record Type: Monograph
Abstract: An intensive investigation was conducted to evaluate membrane performance and effectiveness. The main objectives of this study were to: develop a nondestructive test method for evaluating the interity of membranes in place; investigate the effectiveness of membranes, relative to chloride barrier properties, as a function of membrane integrity; and evaluate the factors that may affect membrane performance, including membrane type and age, climate, and deicer application rate. A nondestructive methodology using ultrasonic pulse velocity was developed to predict the membrane status. It was found that preformed membrane systems reduce chloride intrusion, when properly installed and overlaid with at least 2.5-in. hot-mix asphalt, which should be kept in a good service condition.
