Condition Analysis of Concrete Bridge Decks in Utah available in PDF, EPUB and Kindle. Given the need for increasingly cost-effective strategies for bridge deck maintenance, rehabilitation, and replacement, the Utah Department of Transportation (UDOT) initiated this research to ultimately develop a protocol offering guidance as to whether deteriorated bridge decks should be rehabilitated or replaced.

Condition Analysis of Concrete Bridge Decks in Utah available in PDF, EPUB and Kindle. Several evaluation techniques were employed to assess concrete bridge deck condition, including visual inspection, hammer sounding and chaining, dielectric measurements, ground-penetrating radar imaging, resistivity testing, half-cell potential testing, and chloride concentration testing. The condition assessment testing confirmed that chloride-induced corrosion of reinforcing steel is the primary mechanism of deck deterioration and that inadequate cover over the upper steel mat facilitated accelerated corrosion damage in many instances. The bridge deck condition analyses produced from the results of non-destructive testing were compared to the visual inspection ratings assigned to each deck by UDOT.

Concrete Bridge Deck Condition Assessment Guidelines available in PDF, EPUB and Kindle. Although the substructures and superstructures of bridges in Utah are in relatively good structural condition, the bridge decks are experiencing observable deterioration due to the routine application of deicing salts and repeated freeze-thaw cycling. 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.

This book was released on 2018. Effects of Surface Treatments on National Bridge Inventory Condition Ratings for Concrete Bridge Decks in Utah available in PDF, EPUB and Kindle. Although the application of surface treatments on bridge decks is expected to positively impact bridge deck condition, the effectiveness of specific surface treatments on extending bridge deck life has not yet been quantified on Utah bridge decks. Therefore, the objectives of this research were to develop and analyze deterioration curves for bare concrete bridge decks and decks with specific treatments commonly used in Utah. The scope of this study was determined by the types and extent of electronically available data, including selected static inventory information; maintenance, rehabilitation, and reconstruction histories; and National Bridge Inventory (NBI) condition ratings for the bridge decks.
