Roll of Honor

Roll of Honor

Established in 1965 the Roll of Honor is the highest level of recognition conferred by the Asphalt Institute. Individuals selected for award to the Institute’s Roll of Honor have contributed tremendously to the asphalt industry through either sustained technical achievement or through the substantial contribution of leadership. Roll of Honor status is typically granted as a career capstone event for the recipient.

The inauguration of the Asphalt Institute’s Roll of Honor in 1965 marked the first step in fulfillment of a long-felt need to record, in continuing approbation, the names of those whose contributions to the asphalt industry have been outstanding and proven by time.

Since then and in each succeeding year, the names of persons to be honored by election to the Roll of Honor are selected on a merit basis encompassing the careers of both living and deceased nominees. The Institute’s Personnel Advisory Committee is responsible for oversight of this program to honor individuals annually.

The announcement of the names of those selected is made at Asphalt Institute annual meetings. As of 2004, the Institute awards each Roll of Honor recipient the Asphalt Institute award medallion – a polished brass medallion with engraved AI logo and images of the liquid asphalt supply industry.
