5. Heavy duty pavements
GENERAL
In harbours and harbour terminal large wheel loads can occur by the heavy lifting equipment typically used in these facilities. Different pavement structure is therefore necessary to support these loads.
For these pavements mostly a sand cement stabilization foundation is used. In the example that is prescribed in this chapter there is give a traditional construction that is used in the harbor of Rotterdam. Next to this traditional construction a similar construction with RoadCem is calculated.
DESIGN CRITERIA.
For the design criteria, the same criteria are applicable for the harbor except for the wheel load and the soil type is well graded sand.
The wheel load and the frequents of a typical harbor terminal is given in table B.6.1
