Verge repair with the KLEISER®bh

Roads in rural areas are deliberately kept narrow, partly to keep costs down, and partly as a traffic calming measure. This makes it inevitable that the verges are used when large trucks or agricultural vehicles meet oncoming vehicles. Verges will, therefore, periodically suffer wear, which puts road safety at stake. Road managers have to repair the verges regularly to keep the road up to standard.

However, if verges are kept properly maintained, repair costs for damage to the road surface, such as subsidence and cracks in the asphalt, are avoided.

KLEISER®: vervanging of aanvulling?

Er zijn 2 redenen om de kwaliteit van bermen op peil te houden: ten eerste natuurlijk de directe verkeersveiligheid. Ten tweede voorkom je hoge herstelkosten wanneer er sprake is van schade aan de wegverharding, zoals verzakkingen en scheurvorming in het asfalt.

Soms, zoals in De Wolden, wordt al het bermonderhoud overgenomen door de KLEISER®-methode. In andere gevallen worden de KLEISER®-machines ingezet ter aanvulling van je eigen bermherstelmethode. Denk aan het aanvullen van bermen met nieuw halfverhardingsmateriaal: in plaats van elk jaar de bermen aan te vullen met nieuw materiaal, kun je de bermen bijvoorbeeld 2 of 3 jaar laten ‘kleisen’, waarna er weer een aanvulling met nieuw halfverhardingsmateriaal plaatsvindt. Deze methode voerden wij uit in Kampen en Zuidhorn.

In Ommen en Hardenberg wordt het ‘kleisen’ met name ingezet als aanvulling op de bermvijzels die men daar in eigen beheer inzet. Is het beperken van de verkeershinder van belang, dan heeft het kleisen duidelijke voordelen ten opzichte van alternatieven. Zie, voor een vergelijking, ook onderstaande tabel:

Sometimes, as in the municipality of De Wolden, all the verge maintenance that was previously carried out using a tilting bucket is now done using Kleisens. In other cases, the old methods have been partially replaced by Kleisens. Instead of refilling verges every year with a semi-hardening layer, verges are repaired with Kleisens until refilling with new material is inevitable. This method is used, for example, in Kampen and Zuidhorn.

In Ommen and Hardenberg, Kleisens are mainly used to supplement the augers used to maintain verges which are used by the local authorities. If limiting disruption to traffic is important, the Kleisen offers clear advantages over the alternatives. See, for comparison, the adjacent table:

The advantages of the KLEISER®bh

Filling holes in verges with material from elsewhere is ecologically undesirable, and becoming increasingly problematic. For water drainage, the surplus soil must be removed afterwards. This is a costly process that will only become more expensive due to ever-stricter environmental regulations in the future.

KLEISER®bh restores road safety. That is paramount. The above table already shows that the Kleisens are head and shoulders above the competition. We would like to highlight a few notable points:

  • viable pieces of turf are brought to the edge of the road, so the turf revives relatively quickly
  • verges become greener, which promotes the growth of the flowers so important to insects
  • lower energy consumption (maximum power consumption is 4 kW)
  • little disruption to passing traffic
  • is ideal for use on grass and soil around the edges of cycle paths, among others

NB. The KLEISER®bh is not suitable for lowering verges which are structurally too high. In these circumstances, other equipment, such as a verge cutter, is more efficient.

How much verge do we repair per day?

The work rate currently averages between 2 and 6 km a day. The speed depends on the type of verge, objects such as trees on the verge, and traffic volumes.
