Effect of Dowel Bar Arrangements on Performance of Jointed Plain Concrete Pavement (JPCP)

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...

Performance of Dowel Bar Retrofitted Concrete Pavement Under HVS Loading

The California Department of Transportation uses Dowel Bar Retrofit (DBR) as a rehabilitation strategy for concrete pavements. Two test sections were dowel bar retrofitted and a third section was designated for control on US 101 near Ukiah, California. All three sections were subjected to accelerated pavement testing using the Heavy Vehicle Simulator (HVS). The HVS results demonstrated a large ...

Sensitivity quantification 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...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
