PAVEXpress is a free web-based pavement design tool available for use by local agencies, engineers, and architects who need a reliable way to quickly determine the necessary pavement thickness for a given section of roadway or project. PAVEXpress creates technically sound pavement structural designs for both asphalt and concrete pavements based on widely accepted industry standards from the American Association of State Highway Transportation Officials (AASHTO).
PAVEXpress was designed to be an extension of AASHTO 93/98 and has been adopted by public agencies such as the Washington State Department of Transportation as an accepted tool to help assess, scope, and design pavements. PAVExpress has expanded to help users design asphalt overlays, porous asphalt sections, perform life cycle cost and layered elastic analyses, as well as perpetual pavement design incorporating PerRoad.
