Simplified Approach for Structural Evaluation of Flexible Pavements at the Network Level

Currently, there is no simple procedure available to identify structurally weak pavement sections using Falling Weight Deflectometer (FWD) data at the network (e.g., city, state, county) level. The current methods are either too complex to be applied at the network level or require detailed parameters that are not usually available or commonly collected by transportation agencies. A simple method is needed to determine the structural condition of pavement sections that can be directly implemented and automated in the current pavement databases. The objective of this research study is to develop a simple analysis method to determine the structural condition of pavements using currently available non-destructive testing (NDT) deflection measurement devices at the network level that can be directly implemented and automated in the database of a typical transportation agency (such as Texas Department of Transportation [TxDOT]). In addition, this proposed study aims to run an advanced three-dimensional (3D)-Move simulation analyses to mimic the FWD deflection bowl obtained from the field in an effort, for the first time, to reduce the need to run extensive FWD testing on the network level. The proposed project will produce a more robust, but simple and practical, methodology for the structural capacity evaluation for flexible pavements at the network level. Hence, with this approach, more informed decisions about the most suitable maintenance and rehabilitation strategies can be made.
