Pavement engineering is a branch of civil engineering specializing in the analysis, design, construction and maintainance of street, highway and airfield riding surfaces, for rubber tired vehicles. A pavement is treated as a complex engineering system, whose response and performance results from the interaction of three equally important components: (a) The man-made layers; (b) The natural supporting layers; and (c) The geometry of the applied loads. Consequently, pavement engineering relies on expertise derived from structural, geotechnical, transportation and construction engineering. Coursework in pavement engineering exposes students to a variety of pavement design methodologies, including those by AASHTO (empirical and mechanistic), the Asphalt Institute and the Portland Cement Association. It also builds on their undestanding of 2 and 3-D analytical procedures, soil and aggregate material behavior, and traffic prediction. Research activities focus on three cardinal issues, namely the development of improved: (i) Failure models; (ii) Material characterization procedures; and (iii) Techniques to account for the stochastic nature of the pavement problem. UC investigators explore advanced concepts of fracture mechanics, reliability processes and dimensional analysis.
