MPC Research Reports
Filter by Keyword12 report(s) found with fibers in the keywords field Fibers are used in an asphalt mix to improve its durability and resistance against distresses, such as rutting and cracking. Consequently, accurate rheological and performance characterization of asphalt binders and mixes containing fibers is of vital importance. With increased concerns over the environmental... Fiber reinforced polymer (FRP) composite materials have been studied and applied to reinforced concrete (RC) structures for strengthening or seismic retrofit for many years. This research is related to using FRP composites in new bridge structures. Capacity degradation in RC components of existing bridges... The use of deicing salts on highway bridges has decreased the service life of bridge decks due to the accelerated corrosion of the steel reinforcement. The use of Glass Fiber Reinforced Polymer (GFRP) in bridge decks as a means of corrosion-mitigation has been met with some success; however, GFRP is... This report presents a research program studying the grooved bonding schemes of composite sheets (carbon fiber reinforced polymer, CFRP) for rehabilitating concrete members. The first phase of the research presents the efficacy of functional periodicity on controlling the occurrence of interfacial failure... The use of Carbon Fiber Reinforced Polymers (CFRP) for the repair of civil infrastructure has been on the rise. Most studies have focused on the effect of CFRP to increase the stiffness and strength of reinforced concrete beams or columns. Limited attention has been given to the effect of CFRP on mitigating... Concrete infrastructures in cold areas such as South Dakota tend to experience early deterioration that is mostly triggered by steel corrosion. The corrosion is initiated by chloride penetration through cracks in the concrete. Fiber reinforced concrete (FRC) is known to be a good alternative to conventional... This report presents a two-phase research program studying i) galvanic current influencing deterioration of carbon fiber reinforced polymer (CFRP) sheets bonded to a steel substrate and ii) electrochemical reaction for steel beams strengthened with CFRP. The first phase of the research presents an experimental... The long-term objectives of this project were to develop and validate an instrumentation package for structural health monitoring of bridges subjected to overweight trucks and to develop plans for field deployment of the instrumentation on a pilot scale. Ultimately, the objective is to accurately correlate... This report presents a two-phase research program studying i) the interfacial response of near-surface-mounted (NSM) carbon fiber reinforced polymer (CFRP) strips embedded along a concrete substrate at elevated temperatures and ii) the behavior of NSM CFRP strips for strengthening concrete members subjected... This report presents a two-part research program examining the performance of constructed bridges in a cold region, represented by those in the State of North Dakota, and the behavior of concrete members strengthened with carbon fiber reinforced polymer (CFRP) composite sheets in such a service condition.... |
