Table 5.6 General Mix Design Recommendations.
It is noted that the values in the above figure are a starting point for the design and in no way represent the final and optimal design for each given project and field conditions.
Then values given in the table are accurate enough to allow for techno economic analysis of different alternatives. If the RoadCem alternative as defined in the guidelines is accepted as the one to be considered further, detailed analysis need to be implemented and this would involve field and laboratory tests to determine more accurately the input parameters needed for the final design.
What we in fact have is a classical “Rubic Cube” design problem which we can graphically represent, as in table 5.6. Each element of the Rubic cube will have an associated dose for Cement and RoadCem. Once these doses are established from the general guideline table 5.6 samples need to be prepared with the actual soil that will be used in the pavement structure and a predetermined set of tests carried in the laboratory to obtain the actual design parameters for the final design. This will determine the thickness of the pavement structure.
