Interests:
Dr. Chatti's research interests are in the areas of pavement response
and performance modeling, dynamics of pavements and truck-pavement interaction,
pavement surface roughness, pavement preservation, and characterization
of asphalt concrete mixtures. Current research has been focused on (i)
the effect of design and construction factors on the response and long
term performance of pavements, (ii) the effect of heavy trucks with
large axle groups on pavement performance, (iii) the development of
roughness diagnosis tools for PMS application, (iv) the effectiveness
of preventive maintenance treatments, and (v) dynamic backcalculation
of flexible and rigid pavement parameters.
