Dr. Zaabar's research interests are in the areas of pavement response and performance modeling, dynamics of pavements and truck-pavement interaction, pavement surface roughness, infrastructure sustainability and Surface Properties - Vehicle Interaction, pavement preservation, and characterization of asphalt concrete mixtures. Recent research has been focused on (i) models for estimating the effect of pavement surface condition on vehicle operating costs, (ii) infrastructure sustainability, (iii) Surface Properties - Vehicle Interaction, (iv) assessment of pavement acceptance criteria, (v) the effect of heavy trucks with large axle groups on pavement performance, (vi) the development of roughness diagnosis tools for PMS application, and (vii) dynamic backcalculation of flexible and rigid pavement parameters
