Using Rolling Deflectometer and Ground Penetrating Radar Technologies for Full Coverage Testing of Jointed Concrete Pavements

Selecting the optimal rehabilitation strategy for old Jointed Concrete Pavements (JCP) continues to be a daunting challenge for TxDOT engineers. The variability of joint load transfer efficiency and slab support along projects are major issues contributing to both strategy selection and performance. The presence of water trapped beneath slabs can also be a major limiting factor in strategy selection.
