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

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...

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...

Smoothness variations in early-age jointed plain concrete pavements

This paper discusses the variations in the early-age pavement smoothness at different measurement times and locations in three jointed plain concrete pavements ( JPCPs) representing different ranges of construction times. Surface profile measurements were made during the early morning and late afternoon hours at different locations of the instrumented JPCPs during the first 7 d after constructi...

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...
