Field Measurement and Analysis of Post-Tensioned Prestressed Concrete Pavement Behavior under Tensioning

摘要: This research was conducted to analyze the behavior of PTCP (Post-Tensioned prestressed Concrete Pavement) under tensioning by performing field tests when experimental slab being constructed. The displacements in environmental loading and were measured using temperature measurement sensors displacement transducers. Tensioning performed three times appropriateness could be determined investigating relationship between displacement, transverse crack, daily change displacement. results this study showed that first at very early age, large observed only near joints because friction underlying layer concrete inelasticity. Under consecutive tensioning, clearly all over slab, but still affected friction. In addition, appropriate ensured one-slab even though cracks existed.
