  Figure 5.18 RoadCem based effect of increasing spread of wheel load through modification of In-situ material.
In order to further understand the RoadCem Method we now also need to consider the performance of the pavement structure.
Pavements deteriorate gradually with time for a number of reasons, the two most important being:
• Environmental effects.
• Traffic loading, comprising effects caused by wheel loads and tire pressures, and which is dependent on the stresses and the number of times they are applied.
These factors have the effect of reducing the riding quality of the pavement, as manifested by obvious visible features such as surface roughness, rutting and cracking. In figure 5.19 the manner in which the damage develops for an asphalt pavement is illustrated.
