Overlay Design Asphalt Institute Method

This spreadsheet calculates the design maximum allowable traffic loading for an asphalt overlay in accordance with the Asphalt Institute standard.

The spreadsheet takes user inputs for loading conditions, the existing asphalt rebound deflection and asphalt overlay design parameters. It then estimates the existing asphalt pavement remaining allowable traffic loading, and then calculates the design allowable maximum traffic loading for the overlain asphalt pavement.

The spreadsheet also includes a unique tool allowing the user to see the effects of different asphalt overlays thicknesses.
