The manual offers a practical, cost‑effective guide for state highway agencies to protect, repair, and rehabilitate concrete bridges exposed to chloride‑laden environments, focusing on chloride‑induced reinforcement corrosion. It presents methods for estimating service life and remaining life of bridge components, economic models for selecting cost‑effective approaches, and compares standard physical, chemical, experimental, and rapid protection, repair, and rehabilitation techniques—including milling, hydrodemolition, and pneumatic breakers. The manual demonstrates that combining the strengths of the three removal methods yields superior protection, repair, and rehabilitation outcomes.
This manual is a practical guide for state highway agency personnel who are faced with the day-to-day task of cost-effectively protecting repairing, and rehabilitating concrete bridges exposed to chloride laden environments. The manual addresses the chloride induced corrosion of reinforcing steel. Methods are presented to estimate the service life and remaining service life of concrete bridge components. Economic models are presented to enable selection of the most cost effective methods. These methods include standard physical, chemical, and experimental protection, repair, and rehabilitation. Also, rapid bridge deck protection, repair, and rehabilitation methods are presented. Two mechanized concrete removal methods, milling and hydrodemolition, are compared to the traditional method, pneumatic breakers. The advantages of combining the strengths of the three removal methods are also presented.
