European specifications require SMA aggregates to have no more than 30 percent Los Angeles (L.A.) abrasion loss (AASHTO T96) and no more than 20 percent flat and elongated (F&E) particles when measured at a 3:1 ratio of length to maximum thickness (ASTM D 4791). However, these strict aggregate requirements were developed for use in Europe due to degradation issues with the use of studded …

no more than 35 to 40% of flat particles. Mehta and Monteiro (1993), state that flat and elongated particles should be limited to a maximum of 15% by weight of total aggregate. In general, it is preferable to have somewhat equidimensional rather than flat, thin, or elongated particles. The amount of flat and elongated particles in coarse aggregate
