Various potential sources of distress and the possible areas affected in the roadway, superstructure, substructure, approaches, slopes, and channel of a bridge are described. Guidance for avoiding or correcting such troubles is also provided in the form of a day-to-day maintenance and preventive maintenance guide.
This publication provides introductory technical guidance for civil engineers, bridge engineers and construction managers interested in maintenance and repair of steel and concrete bridges.

book provides complete coverage of concrete bridges from planning, design, repair, maintenance, and demolition, with a focus on small- and medium-size bridges. This handbook offers a global overview of bridge management based on the knowledge and experience of the authors, as well as presents rational and objective criteria to aid in decision-making.
Preventive maintenance—Preventive maintenance procedures are done before deterioration is visible and the structural concrete member is still in good condition, and are usually planned at the design stage and started accordingly.
Procedures include sealing, washing, caulking, and crack repair. ROUTINE MAINTENANCE Routine maintenance is combined with bridge inspection and preventive maintenance. Preventive Maintenance (PM) is the recurrent day-to-day, periodic, or scheduled work that is required to preserve or restore a bridge so that it can be effectively utilized as intended.

The book ‘Bridge Inspection and Maintenance’ was first published in As this book was very popular amongst field engineers, the second revised edition was published in updating the chapter on repairs to concrete bridges.
The third revised and enlarged edition has now been brought out to fulfil the continuous demand for the book. Since. Maintenance of Concrete Structures for Durability of RCC Members Modern concrete is a very durable construction material and, if properly proportioned and Many concrete structures, however, were constructed using early concrete technology, and they have already provided well over 50 years of service under harsh conditions.
ROUTINE MAINTENANCE OF CONCRETE BRIDGES. REPORTED BY ACI COMMITTEE Experience of highway operation has shown that continuous and systematic maintenancce of bridges extends their service life and reduces their operating costs.
Nevertheless, the maintenance of bridges and their approaches are often the most neglected aspect of highway operation. TABLE OF CONTENTS – MAINTENANCE AND REPAIR CHAPTER 32 FILE NO. TABLE OF CONTENTS – MAINTENANCE AND REPAIR CHAPTER 32 FILE NO.

Standard Specifications for Construction and Maintenance of Highways, Streets, and Bridges Adopted by the Texas Department of Transportation November.
Their report, "Routine Maintenance of Concrete Bridges," appears in the October issue of Concrete International (pages ). It discusses cleaning and flushing surfaces, joints and drains; maintaining the bearings, the substructures, and the adjoining slopes; leveling and surfacing the approaches; and keeping the stream channels clear.
Repair of concrete in highway bridges - a practical guide • Define the objective and constraints of repairs. • Prepare a repair strategy and determine viable options.
• Carry out whole life costing. • Select a repair method. • Selection of materials. • Prepare specification for repair. • Surface preparation. TxDOT has established standards and specifications for the construction and maintenance of highways, streets and bridges. Below are links to documents and important information for contractors and professional service providers.

This includes such as cleaning, removing debris or the manning and servicing of movable bridges.
In addition, routine maintenance will cover repairing occasional damage and dealing with other unexpected events. Standard Specifications for Construction and Maintenance of Highways, Streets, and Bridges Adopted by the Texas Department of Transportation November 1, Concrete Bridge Repair & Maintenance Solutions for Bridge Repair and Maintenance When subjected to the elements, even the most well designed concrete bridges need repair and protection in order to ensure that their intended design life can be achieved.
There are several routine maintenance operations, such as cleaning of drainage channels, washing down bearing seats, etc., should be carried out in all bridges.
For other maintenance work such as repair of deteriorating concrete, cost analysis has to be carried out to determine the best treatment. Preventive maintenance is a more planned — and generally more cost-effective — approach to maintaining bridges. It is proactive rather than reactive.
Maintenance is done to preserve (not simply repair) entire bridges and their components, prevent future deterioration, and sustain or improve their condition. The majority of the steel bridges in the interstate highway system were constructed between and ; up until the mid s, virtually all steel bridges were protected from corrosion by three to five thin coats of lead and chromate containing alkyd paints, creating dramatic complexity and cost increases for major and routine level bridge.Region bridge maintenance personnel are responsible to inspect all bridges and designated minor structures annually.
