QUANTITATIVE MICROSTRUCTURAL INVESTIGATION OF DETERIORATED REINFORCED CONCRETE BRIDGE DECK

A reinforced concrete bridge deck located in Albion, Michigan was subjected to quantitative microcrack analysis for assessment of its health condition. Statistical sampling and quantitative microscopic techniques were used in the investigation. A dedicated software system was developed for image analysis of concrete planar sections and stereological analysis of data to quantify the microscopic system in concrete. The bridge deck under investigation was divided into three subregions with different damage conditions. Statistical analysis of the quantified features of the microcrack system revealed significant difference in concrete microcrack conditions between different subregions. The results emphasized the value of quantitative microscopy in assessment of the health conditions of concrete based infrastructure systems and the relation between microcracks characteristics and transport properties.
