3.7.3  RoadCem construction
                  The costs for the RoadCem construction are as follows; in this paragraph these costs are
                  extended based on the unit costs given in paragraph 3.7.2. The construction of the RoadCem
                  construction is divided in 5 steps
                      -   Step 1: Scarifying, excavation and preparation.
                      -   Step 2: Leveling and pre-compaction.
                      -   Step 3: Applying RoadCem and Cement.
                      -   Step 4: Curing.
                      -   Step 5 Wearing courses.

                  In appendix 4 the cost calculation is given for the steps. The total costs are presented in table
                  3.19 to table 3.23 the construction costs are summarized for each road type.
