Incorporating Pavement Structural Capacity into TxDOT Pavement Management Information System
The research team will provide the Texas Department of Transportation (TxDOT) a means to use Traffic Speed Deflectometer (TSD) data to assess the structural condition of their roadways at the network-level by (a) leveraging TSD measurements and pavement data from existing databases in the US to complement the information collected in Texas for proposing and validating indices derived from velocity-based TSD measurements. To do this, the research team will develop a novel, velocity-based methodology for analyzing TSD data, as existing approaches rely on deflection-based methods not suited for the TSD, consider appropriate velocity indices and thresholds for classifying pavement structural condition, assess load transfer efficiency of jointed pavements, and ensure seamless integration of these data into PMIS.
