Partial rehabilitation of road structures

The public usually takes notice of large-scale road construction projects, because they are spectacular, disputed or simply conspicuous. The vast majority of road job sites, however, are completed within a few days time. This is called “partial rehabilitation”. Especially in city centres, industrial estates and residential areas, there is virtually no road that maintains its original state over the years.

Rehabilitation by way of “mini job sites”

Roads can require the most varied kinds of work. Such mini job sites include rehabilitation measures like, for instance, the removal of minor damages such as potholes. Other causes are poorly visible markings that are replaced by the road authorities – but not without milling off the old lines and arrows first. Residential areas and industrial estates, in particular, require civil engineering work when pipes need to be replaced or new supply lines laid. Expanding towns or villages often need pedestrian or bicycle paths that run at the side of the road.

Perfect site organization

It is therefore all the more important not to treat such measures lightly but – as with the large projects – to act in a well organized manner to ensure that the repair will not turn continuous pavements into rag rugs.

Using smaller machines

Even though the machine technology remains the same, it is advisable to use a “downsized” version of the road construction machinery. Special small milling machines, compact pavers and rollers with smaller drums are generally used for this type of rehabilitation contract.
