Pavement designers have been given limited options and the financial resources of project owners held hostage for several decades by design methodologies, laboratory test procedures and stabilizer products, all whose use became standard practice in the middle of the last century, long before the age of computers and computer-aided testing and design programs. In the United States, the highway agencies of 50 different states operate according to 50 different sets of design and test methods that are now seriously dated. Federal Highway Administration (FHWA) and the American Association of State Highway and Transportation Officials (AASHTO) organizations have made a best effort over the past several decades to refine and promote internationally recognized technology that is far more sophisticated and cost-effective. Computer-aided design and testing methodologies ask and answer more questions and provide the opportunity to implement more intelligent pavement designs and to take advantage of the best available product technology. What’s the incentive to move forward? Documented cost savings of 25% to 40% on overall project costs and pavement service life extended by factors of three to four times. Following here are hyperlinks to a series of White Papers providing a more in-depth review of this timely convergence of advancements in technology.
