3D Finite Element Modeling of Dowel Jointed Plain Concrete Pavement

Simulation of early-age Jointed Plain Concrete Pavement deformation under environmental loading using the Finite Element method

The objective of this study was to quantify the early-age Portland Cement Concrete (PCC) slab deformations due to pure environmental loading at critical periods immediately following construction. A newly constructed Jointed Plain Concrete Pavement ( JPCP) section on highway US-30 near Marshalltown, Iowa, USA was instrumented to monitor the pavement response to variations in temperature and moi...

Evaluating the Performance of Dowel in PCC Pavement of Roads using ABAQUS Finite Element Software

In Portland Cement Concrete (PCC) pavement of the roads, dowels bar transfers vehicle loading to the unloaded slab. Load Transfer Efficiency (LTE) is used to evaluate dowel bars in PCC pavement. This parameter is defined as the vertical displacement ratio of the loaded slab versus the unloaded slab. In this study, the impact of effective factors (friction coefficient between dowel and concrete ...

Sensitivity quantification of jointed plain concrete pavement mechanistic-empirical performance predictions

Effect of PCC Material Properties on MEPDG Jointed Plain Concrete Pavement (JPCP) Performance Prediction

This paper focuses on comprehensive sensitivity analyses of various rigid pavement scenarios. Jointed Plain Concrete Pavement ( JPCP) sections designed for three traffic levels in each of five climate zones are evaluated in the sensitivity analyses. One-at-a-time (OAT) local sensitivity analysis was implemented using a design limit normalized sensitivity index (NSI) to provide both quantitative...

Global Sensitivity Analysis of Jointed Plain Concrete Pavement Mechanistic-Empirical Performance Predictions

The new AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) provides pavement analysis and performance predictions for various what-if scenarios. MEPDG performance predictions for anticipated climatic and traffic conditions will depend on the values of the input parameters that characterize pavement materials, layers, design features, and condition. A comprehensive global sensitivity ana...
