JTRP Technical Reports
Cracking in concrete bridge decks can result in increased susceptibility to deterioration. As cracks provide direct routes for the ingress of deleterious elements to the reinforcement and superstructure, cracking can lead to reduced service lives for bridge structures. Several factors affect the extent of cracks which develop in bridge decks; however, relatively few are within the control of the designer. The objective of this research was to evaluate the influence of design parameters on the performance of bridge decks with respect to cracking and to develop simple design tools that are appropriate for both steel and nonmetallic reinforcement. This research …

JTRP Technical Reports
The primary maintenance problem with bridges in Indiana has been deterioration of the concrete deck which is often related to corrosion of the reinforcing steel. While a corrosion protection system consisting of epoxy-coated reinforcement in combination with 2-1/2 in. of Class C concrete cover has been used in Indiana, research and experience have demonstrated that this system can be compromised. As an alternative solution to the corrosion problem in reinforced concrete, fiber reinforced polymer (FRP) bars which are corrosion resistant can be provided as reinforcement. This research was divided into two phases directed towards the implementation of a nonmetallic reinforced …

JTRP Technical Reports
The efficient repair and replacement of concrete pavements and bridge decks often requires a rapid setting material that can be placed, cured, and opened to traffic in a relatively short period of time. Frequently, temporary repairs are made using materials that are later found to be incompatible with the existing pavement, structures, and environment. This practice causes these materials to fail prematurely, frequently requiring re-repair. Research is needed to determine which rapid setting repair materials demonstrate the best behavior with rapid strength gain, low potential for cracking, and excellent durability. The objective of this research is to evaluate the performance …
