1. Packing theory-based Framework for Performance Evaluation of Unbound Granular Materials
Abstract : Enhancing the load bearing quality of granular layers is fundamental to optimize the structural performance of the pavements. Unbound granular materials are one of the most used materials in the base layers of pavements. There have been growing interests on the behavior of unbound granular material in road base layers.

4. Air-coupled microphone measurements of guided waves in concrete plates
Abstract : Quality control and quality assurance of pavements is today primarily based on core samples. Air void content and pavement thickness are parameters that are evaluated. However, no parameter connected to the stiffness is evaluated. READ MORE

5. Non-contact surface wave measurements on pavements
Abstract : In this thesis, nondestructive surface wave measurements are presented for characterization of dynamic modulus and layer thickness on different pavements and cement concrete slabs. Air-coupled microphones enable rapid data acquisition without physical contact with the pavement surface. READ MORE
