This paper discusses the areas of the AASHTO Guide for the Design of Pavement Structures that are expected to be impacted by the Strategic Highway Research Program's Long-term Pavement Performance study results. These areas include the design equations, serviceability measurements, materials characterization, and rehabilitation. Each of these areas are discussed in detail. The areas of the Guide that could be impacted are also noted and tabulated: rehabilitation and maintenance; effective soil properties; traffic; and environmental effects.
