Over the years, Fiber Reinforced Polymer (FRP) composites have gained popularity in transportation infrastructure as a material able to restore and increase the capacity of existing concrete elements. Properties such as a high strength to weight ratio, non-corrosive nature, durability, and high malleability make FRP materials an appealing alternative in the reinforcement of these structural elements. However, there are still concerns regarding the...

The ongoing deterioration of highway bridges in Colorado dictates that an effective method for allocating limited management resources be developed. In order to predict bridge deterioration in advance, mechanistic models that analyze the physical processes causing deterioration are capable of supplementing purely statistical models and addressing limitations associated with bridge inspection data and statistical methods. A review of existing analytical...

States' Departments of Transportation (DOT) are trying to utilize the best practices of managing low-volume roads (LVRs) due to limited resources and declined transportation funding. Diverse maintenance practices and fluctuating budget allocations are noticed on LVRs which significantly impact the overall pavement performance. In this study, the optimal scheduling of maintenance strategies and effectiveness of different maintenance policies are investigated....

This study analyzes the effects of temperature change and thermal gradients on deck joint movement and provide recommendations regarding deck joint elimination. The data indicates that temperature shifts and thermal gradients through the depth of the girders along the joint are impacting the bridge's movements and causing changes in stress. A strong parallel is shown between the temperature changes and the study joint's movement and changes in stresses...
