Polsum is located in the south-west of Marl and has retained its village character. Agriculture and forestry are very important, which is why the maintenance of farm tracks and access roads is of great significance. The paths are also important for cyclists, as they form important transport links in the supra-regional cycle path network. As the paths are narrow and partly lined with trees, the work must be carried out with the utmost care so as not to damage the roots.

In conventional road resurfacing, the damaged road surface is completely removed and disposed of or partially recycled. It is then rebuilt in layers. Compared to the in-situ method, this process is characterised by longer runtimes and higher consumption of construction materials, and requires significantly more effort for material transport and disposal.

In Marl-Polsum, on the other hand, the milled road material is crushed directly on the construction site and then solidified with the cement binder NovoCrete® ST 98 and water. This so-called hydraulically bound base course is then levelled and compacted by machine before a new surface course is finally applied. Asphalting can begin after just 24 hours, and less asphalt mix is required due to the high load-bearing capacity of the HGT layer.
