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 :
| 1 | Mass | 2 350 kg/m3 |
| 2 | Coefficient of cubic expansion | 4 / 6 x 10-5/°C |
| 3 | Thermal Conductivity (Design Purpose Lambda value) of | 0.5 W/mK |
| 4 | Control of water vapour |
|
| 5 | Specific heat value | 1,01 x 103 J/kg K |
| 6 | Impact noise insulation value | 7 dB (A) by 25 mm thickness |
| 7 | Electric (antistatic) conductivity resistance | 1013 Ohm/cm |
- Employed in all construction works, like as :
| Waterproofing : | - Roofing, roof top gardens, parkdecks, courtyards |
| Paving : | - Footways, areas for vehicular trafic external loading bays - platforms, terraces |
| Hydraulik works |
