Title: SMA: INNOVATION IN ASPHALT PAVEMENT
Accession Number: 00647317
Record Type: Component
Availability: Find a library where document is available Abstract: SMA is the European pavement innovation that received particular attention by the European Asphalt Study Tour (EAST), a team of pavement specialists from the United States who visited Sweden, Denmark, Germany, France, Italy, and the United Kingdom in 1990 to study European asphalt pavement technology. This pavement innovation is a special-purpose, rut-resistant asphalt surface pavement mixture. It is composed of coarse aggregate held together by a mastic of asphalt cement - mineral filler - stabilizer. Known in Germany as splittmastixasphalt, it can be loosely translated as stone mastic asphalt, which has become the accepted terminology in the United States. At the conclusion of the study tour, the Federal Highway Administration's Office of Technology Applications was assigned the lead in coordinating the evaluation of this technology, adapting it to this country's highway needs and construction characteristics, and implementing it in the United States. This article reports on the accomplishments to date, including (1) background information obtained and summarized in a Technology Synthesis of European SMA Practices and a Model Design and Construction Guideline for use on initial projects in this country, (2) U.S. projects, (3) initial findings, and (4) future developments. At the onset of its fourth year of use in this country, interest in SMA is stronger than ever. Adaptation and refinement of SMA will continue.
