Appendix 6: Cost calculations RoadCem

constructions

Step 1: Scarifying, excavation and preparation
Depending of the situation the location have to be prepared. For the RoadCem construction is
assumed that the soil or existing pavement needs a pretreatment for a depth of the thickness
of the RoadCem-cement layer.

calculated. In table 3.30 are the costs for the preparation per construction summarized:
