Evaluation of Deterioration of Structural Concrete Due to Chloride Entrainment and Other Damaging Mechanisms KYSPR 10-406

OBJECTIVES: Continuation of an Approved Study Anticipated Completion: FY 12 I. Identify the range of structural concrete deteri oration mechani sms encountered by highway agencies and their impacts on structures. Determine effective methods for evaluating the presence/extent of concrete deterioration. 2. Acquire and become familiarized with relevant test instrumentation to evaluate concrete deterioration. 3. Perform in-situ tests of concrete properties/concrete damage assessment of selected bridges/structures throughout Kentucky with various ages and amounts/types of distress. Tests will be performed on bridges decks, barrier walls, retaining wall s, abutments, beams and piers. 4. Prepare a summary of findings and provide recommendat ions/guidance for extended testing of bridge concrete.
