Pavement Structural Condition Evaluation at the Network Level

Project Information

Project ID: 
Project Abstract: 

Conduct theoretical analyses to identify/develop robust measures for network level pavement structural evaluation and pavement structural deterioration performance curves based on responses measured by traffic speed deflection devices; validate those measures with field data on instrumented and other pavement test sections.


Effective and reliable methodologies for developing pavement structural deterioration performance curves that State highway administrations (SHAs) can use in pavement management and national performance management, which capitalize on the advances made in network level, high-speed deflection measurement devices and mechanistic-empirical analysis of pavements. Identification or development of robust measures or indicators that can be reliably related to pavement structural conditions and are based on responses measured by currently available devices.

Project Outputs: 

Preliminary analyses have been conducted using Mechanistic-Empirical (M-E) analysis tools to look at structural deterioration. The results indicate that structural deterioration is nonlinear and accelerate after a certain damage level. Being able to predict when this occurs and how it progresses afterwards will help determine optimum timing for structural rehabilitation, remaining structural capacity, and future budget needs.
