Abstract:This report is the result of a directive from Mr. D. C. Greer, State Highway Engineer, to determine the causes of deterioration in Texas structures and to recommend corrective measures. It is prepared in two volumes. This volume is the Discussion and Summation of the report. Volume II contains the description of Field Survey investigations and records. Selected objectives were as follows: (1) Review of past and current research efforts; (2) Determine the type and scope of concrete deterioration actually occurring in Texas highway bridges; (3) Evaluation of materials used in the manufacture of concrete by laboratory research; (4) Evaluation of available information and actual design and construction procedures used in the manufacture, placement and curing of concrete; (5) Evaluation of structural design to the extent reflected by types of bridges most adversely affected; (6) Effect of maintenance practices which may affect the hardened concrete, such as the use of de-icing salts and sealing of the deck surface; (7) Adequacy of existing test procedures to insure uniform batching, mixing and placement of concrete; and (8) Recommendations which will tend to eliminate or reduce the deterioration of structural concrete on future structures.
