Recent research has been focused on pavement response and performance modeling, dynamics of pavements and truck-pavement interaction, pavement surface roughness and ride quality, pavement preservation, and characterization of asphalt concrete mixtures. Current research includes the investigation of design and construction factors on the response and performance of new flexible and rigid pavements, the effect of heavy trucks with large axle groups on pavement performance, development of improved mechanistically based models to predict pavement performance, the development of surface profile roughness diagnosis tools for PMS application, the development of pavement surface roughness thresholds for the preventive maintenance of pavements, analyzing pavement distress and roughness data for pavement management applications, non-destructive pavement testing and dyanmic backcalculation of flexible and right pavement parameters, and effectiveness of preventive maintenance treatments.
