Stone Mastic Asphalt

  • Stone Mastic Asphalt - Civil Engineering

    Stone mastic asphalt (SMA) is a stone-on-stone like skeletal structure of gap graded aggregate, bonded together by mastic, which actually is higher binder content, filler and fiber to reduce the binder drain. This structure improves the strength and the performance of SMA even higher than the dense graded and open graded asphalt mixtures.

  • Stone Mastic Asphalt (SMA) - Kilsaran International

    Stone Mastic Asphalt (SMA) is a gap-graded mix laid between 30mm and 40mm thickness. It may be manufactured using a polymer modified binder (PMB), giving the aggregate skeleton additional strength. SMA is used in the construction of new roads and overlaying existing roads and offers superior durability and resistance to deformation. SMA must be designed and manufactured in accordance with the ...

  • What is Mastic Asphalt? (with pictures) - wisegeek

    Sep 06, 2019 · The bitumen content in mastic mixtures is typically double that found in concrete asphalt, which helps to bind the particles more closely together to keep water out. In addition to bitumen, mastic asphalt is also made up of aggregate. This aggregate may include sand, gravel, or many other different types of stone products.

  • Mix Types - Pavement Interactive

    Stone Matrix Asphalt (SMA) Stone matrix asphalt (SMA), sometimes called stone mastic asphalt, is a gap-graded HMA originally developed in Europe to maximize rutting resistance and durability.The mix design goal is to create stone-on-stone contact within the mixture. Since aggregates do not deform as much as asphalt binder under load, this stone-on-stone contact greatly reduces rutting.
