A STUDY TO DETERMINE THE CAUSES OF BRIDGE DECK DETERIORATION
This report is Part I of an investigation into the causes of bridge deck deterioration in Oklahoma. The effects of a limited number of factors from bridge design, environment, materials, and construction are discussed. Investigative efforts involved in Part I were statistical analysis of variables from a visual survey, field tests of bridge deflections, visual observations of core samples, and extensive literature review of deterioration causes and failure mechanisms. The nature and extent of surface deterioration based on the study findings was extensive. The ranking order of occurrence among the deterioration types is cracking, scaling, popouts, spalling, and joint spalling. The causes of deterioration were found to be variable as was the case in many previous studies. Lack of quality control in concrete manufacture and aggregate sources and their quality appeared to be standouts in regard to deterioration causes.
