A JPCP consisting of slabs 26 cm thick and 4.2 m wide is considered in this paper.
However, since the emphasis of this research was to compare dowel bar alternatives, rubber bearing was used to simulate the foundation support of JPCP, which could eliminate the effect of accumulated deformation and erosion of the supporting base or subgrade material.
For this study, a newly constructed JPCP section on highway US-30 near Marshalltown, Iowa was instrumented to monitor the pavement response to variations in temperature and moisture during first seven days after construction.
A newly constructed 267 m (10.5 in) thickness JPCP section on a 152 to 260 mm (6 to 10 in) open-graded granular base on US-30 near Marshalltown, Iowa was selected for this study.
There are also some JPCP transverse joint faulting empirical models developed under previous research.
Under the support of Federal Highway Administration (FHWA), Teng establishes the mechanistic-empirical distress indicator prediction models and develops software Pave Spec 3.0 for JPCP .
Milling the existing HMA surface prior to overlay was effective in keeping the overlay smooth, and smoothness performance was improved significantly in all JPCP
and JRCP sections overlaid with HMA, with thicker HMA overlays producing smoother pavements.
A newly constructed JPCP
on US30 near Marshalltown, Iowa, USA was instrumented to evaluate and study the early-age JPCP
behavior in terms of pavement deflection with respect to temperature and moisture variations.
The report, Design and Evaluation of Jointed Plain Concrete Pavement with Fiber Reinforced Polymer Dowels, details laboratory and field evaluations of JPCP
with FRP and steel dowels, analytical modeling of dowel response, and field rehabilitation of JPCP
using FRP dowels.
The results to date in South Dakota indicate no significant performance differences between the 20.3-centimeter and 16.5-centimeter (8-inch and 6.5-inch) fiber-reinforced concrete pavement and the 20.3-centimeter Jointed Plane Concrete Pavements (JPCP
) control sections.
In response to this problem, FHWA initiated research on the development of construction guidelines for fast-track jointed plain concrete pavements (JPCP
The major goal of this project was to develop recommendations for PCC properties and materials characteristics found in higher strength jointed plain concrete pavements (JPCP
) with improved long-term performance as determined by joint spalling and faulting, and transverse slab cracking.
