Monitoring and Evaluating Performance Requirements of Flexible Road Pavements

This paper presents key findings of a research project which is entrusted with setting up guidelines for monitoring and evaluation of pavement performance requirements with the aim of improving durability and both road safety and environmental sustainability. The study has investigated some techniques for monitoring structural and surface characteristics of asphalt pavements, such as Ground Penetrating Radar, Falling Weight Deflectometer, Laser Profilometer, Skiddometer, and has addressed problems arising from the use of these techniques; the paper describes some measures needed to overwhelm them and for optimizing data collection procedures. In order to enhance the evaluation of asphalt pavements, the study has focused on data analysis and interpretation methodologies; it proposes refinements to the existing procedures for both data processing and interpretation.
