The Ideal Asphalt Pavement: Pavement: Design

Selected advances in technology over the past approximately 30 years that permit a well qualified engineer to design an ideal asphalt pavement are discussed in this paper. Discussion concentrates on the use of mechanistic-empirical (M-E) design methodology but is not limited to the use of the new M-E Pavement Design Guide. A design framework is presented considering: 1) input information; 2) distress analyses, and, 3) design decisions. This framework serves as the basis for the information which is presented in each of the three phases of the design process. For Input Information, discussion includes brief summaries of traffic and environmental information, materials characterizations, construction factors, considerations of risk/reliability and appropriate simplifications of these inputs. Distress Analyses include: discussion of the selection of appropriate materials for the specific environment in which pavements will be used (e.g. selection of appropriate PG binder grades for HMA); and, estimates for specific forms and amounts of pavement distress by M-E analyses (where possible) of representative pavement sections. Those distress modes addressed include: fatigue cracking (including consideration of an HMA endurance limit); permanent deformation, all layers considered; low temperature cracking; reflection cracking; and estimates of ride quality. Various distress relationships and their use in analyses are briefly addressed, for example: fatigue and permanent deformation for HMA and permanent deformation for untreated soils and granular materials, based on relationships between stress and/or strain and load repetitions. Design Decisions include considerations of final design sections and materials based on factors such as: economics (life cycle cost analysis); materials availability; limits on thickness material types based on construction time constraints, limited clearances, and potential special loading conditions.
