Reinforced Contraction Joints in Concrete Pavement:
Accelerated Pavement Test and FE Analysis
AB  - Transverse contraction joints are by far the most common type of joint in jointed plain
concrete pavements. Early loading of contraction joints can create a weakened vertical plane
and later grow as a full-depth crack. In this study, load transfer efficiency (LTE) of steel mesh
reinforced transverse contraction joints were studied at accelerated pavement tests (APT).
3D finite element (FE) model of jointed plain concrete pavement (JPCP) was developed to
study deflections and crack propagation in just under the joint of the concrete pavement. The
APT tests were focused on the LTE values before and after the crack initiation under the
contraction joint region. Experiments were performed on three slabs in which two of these
slabs were prepared without reinforcement and one of them was reinforced with steel mesh.
Data generated by APT was used for verification of crack propagation modeling in the finite
element analysis. Steel mesh reinforced slab gave the lowest vertical deflections (51μm) and
highest LTE (91.56%). The LTE value in the reinforced slab after 25,000 passes was 13.63%
higher than the average of unreinforced slabs. The findings suggest that the load transfer
efficiency was found to be a complex parameter and should be interpreted together with
average displacement values when contraction joints are evaluated at early traffic loadings.
