SPECIAL INSPECTION OF POST-TENSIONED CONCRETE BRIDGES ON THE M4 MOTORWAY IN BERKSHIRE

This case study describes the reasons behind the current concern for the integrity of post-tensioned concrete structures, a summary of the current Department of Transport (DoT) programme of special inspections for post-tensioned concrete bridges on the motorway and trunk road network in Berkshire, and the practical issues in carrying out the investigations. It is intended to be informative to other bridge maintenance engineers. Each phase of the special inspections from the desk top study, preliminary site inspection, technical plan for the intrusive investigation, contract documentation for procuring the site works and finally the site investigation is included within the case study. The issues raised are the identification of the high risk structures or post-tensioning systems with regard to sudden collapse and the effectiveness of testing procedures. Conclusions are drawn on the recommendations for further testing, monitoring and maintenance or repair works. (A) For the covering abstract see IRRD 882313.
