The success of the construction of concrete pavements depend mainly on five criteria:
1. The roughness or smoothness of the sub-base
2. Planning and implementation of the formwork
3. Compacting of the concrete
4. Roughening of the surface
5. Curing process
Smooth sub-bases save a lot of expensive concrete. It is also easier to ensure that the pavement itself will be smooth if the sub-base is smooth. Often projects spend too much on their formwork
