INTRODUCTION OF STONE MASTIC ASPHALTS (SMA) IN ONTARIO (WITH DISCUSSION)

In the search for a premium asphalt pavement with greater durability, improved rutting and skid resistance, and reduced traffic noise, paving experts in Ontario have reviewed and evaluated stone mastic asphalt (SMA). These heavy duty paving mixes are characterized by a high content of crushed, quality stone and asphalt cement in mastic form. Known primary as "Splittmastixasphalt," revealing its German origin (Splitt = crushed stone chips), SMA paving mixes were developed in Europe in the early 1970s to address and cope with the effects of the then rapidly increasing traffic in Europe. This paper describes the observations and results of the initial phases of the project.
