Abstract

The main purpose of the foundation is to distribute the applied vehicle loads to the underlying subgrade, without causing distress in the foundation layers or in the overlying layers. This is required both during construction and during the service life of the pavement. The stresses in the foundation are relatively high during construction, although the number of stress repetitions from construction traffic is relatively low and is not so channelised as normal traffic during the service life of the pavement. The standard practice, which is described in this part, is to design the foundation for construction traffic loading. This approach provides a 'standard foundation' for the design of the pavement.
