Definitions and some physical attributes

  • A dense mass, composed of suitably graded mineral matter - chippings, and/or sand, and/or limestone fine aggregate and/or crushed natural limestone powder and bitumen (natural or issued from crude oil distillation)
  • Mastic asphalt, at suitable temperature, may be spread by means of hand float or by mecanical way (finishers), and does'nt need any compaction, contrary to all other asphaltic mixes
  • mastic asphalt, a perfect impermeable mass
  • Mastic asphalt is non toxic (water insoluble) and there fore an ecologic building material
  • Mastic asphalt is basicly - and since ever reusable (recyclable)
  • Some physical attributes of mastic asphalt :
