Research on Transverse Cracks in Continuously Reinforced Concrete Pavements Using Fiber Reinforced Polymer Bars

摘要

In order to further understand those transverse cracks in continuously reinforced concrete pavements (CRCP) using fiber reinforced polymer bars, the CRCP transverse crack spacing and width is investigated, to explore the influence of the transverse crack spacing and the width of the transverse crack on the pavement and the impacts of the tensile strength of concrete, dry shrinkage, temperature shrinkage and FRP reinforcement on the transverse cracks. The transverse crack of continuous reinforced concrete pavement is analyzed by simulation calculation model, optimization design of CRCP reinforcement to control the spacing and width of the transverse crack. Research shows that the concrete and the performance of FRP reinforcement has a certain influence on transverse cracks, the appropriate reinforcement ratio is helpful to control CRCP transverse cracks.
