This manual describes condition assessment methods and threshold values that may be used to determine whether rehabilitation or replacement of a given bridge deck is more appropriate when the severity and extent of deterioration warrant deck improvement. Threshold values given in the manual are based on a questionnaire survey conducted of state departments of transportation nationwide, as well as on standards and guidelines published by the American Society for Testing and Materials, American Association of State Highway and Transportation Officials, and Strategic Highway Research Program.133
