THE ASPHALT REVOLUTION : WHAT HAS HAPPENED IN HOT MIX ASPHALT IN THE PAST 15 YEARS ADDS UP TO AN ASPHALT REVOLUTION

This article presents National Asphalt Pavement Association (NAPA) President Mike Acott's remarks at the 2003 Annual Convention concerning the history of hot mix asphalt developments over the past 15 years. Calling it an "asphalt revolution," he cites the industry's major leap from method specifications where the transportation agency designed and controlled the asphalt mix and the contractor applied it to the current practice of the industry being a partner in designing increasingly robust mixes to withstand the tougher needs of today's larger, heavier trucks and cars. The improvements were made possible by the aggressive combined research program of the American Association of State Highway and Transportation Officials, the Federal Highway Administration and the Transportation Research Board through the Strategic highway Research program (SHRP). In 1986 the National Center of Asphalt Technology was created and endowed with more than $10 million. In the early 1990s, three key publications were produced, a paving handbook, a textbook and the rubblizing guidelines. The 1990s saw immense growth in practitioner-oriented research and Superpave guidelines were formalized in the mid-1990s. Recently, NAPA has issued its new guide to hot mix asphalt pavements, with a CD-ROM; perpetual pavement is being studied; methods to make pavement quieter are being looked at, and in mid-2002, NAPA went on a study tour of Europe to learn more about warm-mix technologies.
