Incorporating Slab/Underlying Layer Interaction into the Concrete Pavement Analysis Procedures

The objective of this research is to develop a mechanistic-empirical (M-E) model and associated software to consider the interaction between the slab and base layer and its effect on pavement performance. The researchers reviewed available literature concerning laboratory and field efforts to characterize slab-base interaction. In-service and experimental pavement data were used to identify important factors surrounding slab-base interaction and pavement performance. The researchers also evaluated available models for slab-base interaction and pavement performance in jointed plain concrete pavements and continuously reinforced concrete pavements, including those of the AASHTO M-E procedure. Alternative models for the AASHTO M-E procedure were developed and validated. Finally, rudimentary software was created to allow the models to access existing AASHTO M-E design projects. In this way, the AASHTO M-E software can be used to predict performance given the alternative models for performance and slab-base interaction.
