STONE MASTIC ASPHALT TECHNOLOGY FOR URBAN PAVEMENTS ...

Stone mastic asphalt (SMA) trials in Ontario have proven most favourable. SMA, a dense gap-graded mix with high rugosity, has demonstrated enhanced durability, friction, stability and fatigue properties compared to conventional surface course mixes. Based on this positive experience, Metro Toronto Transportation selected SMA for resurfacing a section of Lake Shore Boulevard during the fall of ...

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.
