President's Perspective shared challenges Cooperative international information sharing and technology transfer moves asphalt pavement industries everywhere forward Outreach to other countries creates a valuable opportunity for NAPA to share information and best practices, and to learn from others. Communicating about common issues helps everyone identify global trends and use that information strategically. Many new developments and regulations in asphalt pavement have come about as the result of cooperative efforts to share information across borders. Cooperatively identifying global trends give our industries the opportunity to take proactive measures to address imminent regulation, and sharing information for new technology transfer helps all countries make progress in asphalt pavement developments. Strategic Outreach As the national association for asphalt pavement in the United States, it is NAPA's objective to seek out opportunities for information sharing with asphalt pavement industries in other countries. Other asphalt trade associations are a significant source of information. Many countries have their own asphalt pavement association. NAPA, along with our counterparts in Australia, Europe, Japan, and South Africa formed the Global Asphalt Pavement Alliance (GAPA) in 2008, and it now includes Mexico and New Zealand. The GAPA meets annually to share information, identify issues, compare perspectives, and determine courses of action. NAPA also works to cooperatively share information with other international associations, such as Eurobitume and the International Society for Asphalt Pavements (ISAP). One of the most effective ways to pursue in-depth information sharing and technology transfer is to hold an industry scanning tour to a particular country. These tours often include NAPA members and representatives from the Federal Highway Administration (FHWA) and state DOTs. Our most recent scanning tour travelled to Japan to learn about their high reclaimed asphalt pavement (RAP) pavements. The Japanese Road Construction Association (JRCA) was a very accommodating host. The association organized visits to sites crucial to our information gathering and hosted a valuable information sharing event. A report from the Japan scanning tour is in production and will be available shortly. An excerpt from the report is published on p. 24 of this issue of Asphalt Pavement. Years ago a Japanese delegation came to the U.S. to learn from NAPA and our asphalt industry about our methods of creating and constructing porous asphalt pavements, which were first developed in this country. As you can see, these mutually beneficial international relationships have long-term value. NAPA also furthers its international relationships and information sharing through World of Asphalt. Attendees from more than 50 other countries travelled to Baltimore in 2015 for the conference and trade show. In addition to our recent Japan scanning tour for high RAP pavements, here are a few of the Mike Acott, NAPA President developments and technologies that have benefitted the U.S. asphalt pavement industry thanks to international cooperation: Stone Matrix Asphalt In fall 1990, NAPA organized the European Asphalt Study Tour. Stone matrix asphalt (SMA) as a surface mixture was identified as a promising asphalt technology worth pursuing in the U.S. Several months later, the FHWA created a technical working group (TWG) that included members of the study tour. By 1997, at least 28 states had constructed more than 100 projects totaling more than 3 million tons of SMA. Today, SMA is used for improved pavement performance that extends the life of the roadway, reduces noise, and improves resistance and visibility. Warm-Mix Asphalt Warm-mix asphalt was originally developed in Europe in the mid1990s to address the European Union's (EU) required greenhouse gas reduction targets. Experiments with different warm-mix asphalt additives began in Denmark, Norway, and Germany. Warm-mix asphalt first hit our radar when the association was addressing fumes. NAPA sent a warm-mix asphalt study tour to Europe in 2002 and made its first presentation on warmmix asphalt to the membership at the 2003 NAPA Annual Meeting. Research on the new pavement technology, sponsored by NAPA, FHWA, and others, began the same continued on page 10 Asphalt Pavement Magazine - November/December 2015 * 9
