Abstract:Approximately 90% of the steel highway bridges in the United States are protected from corrosion with lead-based paints. Maintenance of the coating system requires the work to be performed in compliance with environmental and worker health/safety regulations. Conforming to these regulations has had a significant impact on procedures and cost. A comprehensive study was performed to evaluate the various factors involved with lead-paint removal. Containment and ventilation systems were studied and recommendations were developed for containment materials, design of joints, design of air inputs, negative pressure, and air flow within containment. Waste disposal is a significant issue due to long-term liability and cost. Tests were performed on hazardous waste characterization, waste minimization, methods of generating non-hazardous waste, and long-term stability of lead-containing wastes and stabilized wastes. Alternate surface preparation methods and costs were evaluated. Recyclable steel abrasive was found to be cost-competitive and to reduce the amount of debris by approximately 90% compared to expendable abrasive. Other surface preparation methods tested were found to have advantages and disadvantages. Advantages included reducing the amount of waste generated and worker exposure (though not below the OSHA Permissible Exposure Limit). Disadvantages included the inability to prepare all surfaces typically found on a bridge and low production rates. The cost of meeting environmental and worker health regulations has increased the cost of the average project by a factor of two or three.
