Fibre Asphalt - Stone Mastic Asphalt Breedon Group

Commonly used asphalts in the UK are asphalt concretes (previously termed ‘bituminous macadams’ or ‘bitmacs’), hot rolled asphalts (HRAs), and stone mastic asphalts (SMAs). Asphalts can further be grouped into roadbase, binder and surface courses, each providing a different function in flexible pavement construction.

STONE MASTIC ASPHALT IN GERMANY

Stone mastic asphalt (SMA) was developed in Germany thirty years ago, principally in order to produce a mix with better resistance to wear by studded tyres. Even though studded tyres were banned in Germany in 1975, SMA continued to be improved and has since increasingly been used. Since 1984 it has been included in the German asphalt specification.
