Seismic Approach to Quality Management of Hot Mixed Asphalt (HMA)

The goal of this project is to develop a seismic data acquisition system and associated software package capable of acquiring surface wave data in a non-destructive, non-contact, rolling and multichannel fashion for the purpose of swiftly and reliably determining and visualizing seismic velocity of newly-constructed asphalt pavement layers for quality management purposes. Processed surface and three-dimensional, lane-wide models of seismic velocity will be georeferenced and mapped.
