| Technology description including background system | The life cycle analysis of mastic asphalt, or sheet asphalt, encompasses the entire cradle to gate life cycle stages, i.e. the processes of extraction of aggregates and the production of bitumen. Consideration was also given to the transport of the individual material components to the asphalt mixing facility as well as the production cost. Transportation from the asphalt producing facility to the construction site have not been taken into account and must be included in the overall system evaluation. In the disposal phase, a mechanical dismantling (asphalt cutter) is accounted for in module C1, taking into account both the consumption of chisle and diesel consumption. It is assumed that the dismantled asphalt will reach the end of waste status immediately after the dismantling. This means that loads for re-use (heating and mixing) are shown in module D. The transport in module C2 to the asphalt mixing plant takes place with a truck (50km). Module D assumes a material loss of 3%. The mixing and heating is also balanced in module D. There will be a credit for the net amount of material (amount recovered minus processing losses) for the substitution of an asphalt track bed. |
