Jointed Plain Concrete Pavements Behavior under
Environmental Loads. Edition No. 1
VDM Publishing House, Sep 2008, Pages: 144
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.
