Stone Mastic Asphalt (SMA) was invented in Germany 30 years ago mostly as a bituminous mixture which better resists the wear of studded tires. Even though studded tires have not been allowed in Germany since 1975, SMA was improved and has been in use increasingly. Since 1984, it has been standardized in the Asphalt Specifications. SMA is a bituminous mixture for surface courses of high stability to resist permanent deformation. It also has a high wear resistance and good durability to cracking and fretting. High quality and quantity of bitumen and of maximum size aggregates are essentials for a long service life of SMA. However, quality has its price and SMA is about 20% more expensive than asphaltic concrete. The state-of-the-art of SMA is outlined, specifications explained, experiences described and case studies presented. Recommendations for mix design, manufacturing and paving are given. Also some information is provided on the contractual system and the cooperation between the client and the contractor which stimulated and fostered the development of SMA.
