Asphalt ist a mix of bitumen, aggregate and additives. Usual asphalt consists to 90 to 95 percent by weight of aggregate and 5 to 10 % of bitumen.

The physical properties are dependent on the temperature of the material, as at high temperatures, asphalt has a very distinctive viscous behaviour, which becomes more and more elastic with dropping temperatures.

As the physical properties are mainly dependent on the used aggregates, they can vary in a large range. Typical values are:

  • heat conductivity: 0.8 - 1.2 W/mK
  • specific heat capacity: 850 - 1050 J/kgK
