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
