Jointed Plain Concrete Pavements Behavior under Environmental Loads

Studies on deformation characteristics of early-ageJointed Plan Concrete Pavements (JPCP) subjected topure environmental loading has drawn significantinterest as it is believed that the early-agedeformation of Portland Cement Concrete (PCC) slabcould result in the loss of pavement smoothness andthe tensile stresses induced by these deformationscould result in early-age cracking. However, thecomplex interaction of several environmental factorshas resulted in difficulties in predicting the JPCPdeformation characteristics under environmentalloading. This book discusses the early-age behaviorsof JPCP under environmental loading. The slabdeformations associated with temperature andmoisture were analyzed using measured verticaldisplacements and pavement surface profilemeasurements. The variation of smoothness atdifferent measurement times and locations areanalyzed and discussed. The early-age deformationbehavior of instrumented JPCP under environmentalloading was also simulated using Finite Element (FE)programs using the equivalent temperature differenceconcept.

Studies on deformation characteristics of early-age Jointed Plan Concrete Pavements (JPCP) subjected to pure environmental loading has drawn significant interest as it is believed that the early-age deformation of Portland Cement Concrete (PCC) slab could result in the loss of pavement smoothness and the tensile stresses induced by these deformations could result in early-age cracking. However, the complex interaction of several environmental factors has resulted in difficulties in predicting the JPCP deformation characteristics under environmental loading. This book discusses the early-age behaviors of JPCP under environmental loading. The slab deformations associated with temperature and moisture were analyzed using measured vertical displacements and pavement surface profile measurements. The variation of smoothness at different measurement times and locations are analyzed and discussed. The early-age deformation behavior of instrumented JPCP under environmental loading was also simulated using Finite Element (FE) programs using the equivalent temperature difference concept.
