4.2.8 Bearing capacity
Figure 4.42 Example of a very plastic soil.
When the user and client requirements are known, the pavement design can start. The first important factor to consider is the soil bearing capacity as this is the factor which determines the bearing strength of the sub-base and in turn has the most influence on the structural pavement design that will be placed on top of this particular soil.
The soil bearing capacity or sub base bearing strength is a material property which is responsible for the way the weight of the traffic is carried off through to the sub-base. There are different ways of determining the bearing strength and it must be known to a depth of minimum of 1,5 meters.
