Figure 5.28 Comparison between Traditional pavement and RoadCem construction.
The final aspect to be considered is the thickness of the pavement structure. Here too some general rules are applied but this factor is also under the influence of the expected life time or the design life time of the road without any or minimal maintanance. The general rules are:
• The higher the wheel load, the thicker the pavement structure is.
• The higher the intensity of traffic, the thicker the pavement structure is.
• The longer the design life of the pavement, the thicker the pavement structure is.
When we combine all of the above factors we end up with general Cement, RoadCem and pavement structure requirements as a function of the soil class as given by the USCS. These general recommendations are used as the starting point for the design and design optimization process shown in figure 5.29 and are shown in table 5.6.
