One exercise was conducted by the Kansas Department of Transportation and the second was performed by Palmer Engineering. There have been two independent verifications confirming PaveXpress calculates pavement designs consistent with the methodologies in AASHTO ’93 and ’98. Since its initial release, PaveXpress has expanded to help users design asphalt overlays, porous asphalt sections, and life cycle cost analyses. 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 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 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.
