HanseGrand Robust
 
          …road shoulders for                   
 
                          highest demands

 

Road shoulders are heavily stressed, in particular at much frequented motorway slip roads and at their trunk roads. In order to prevent larger damage to these surfaces, HanseGrand has developed special building materials which provide permanent solutions here.

Together with experts, a mineral mixture has been developed to produce a qualified shoulder protection – HanseGrand Robust. The requirements: load-bearing capacity, stability and durability. Mixtures adapted to this application area meet the requirements to a high degree.

 

The aggregate-stable, shear-stable, weatherproof HanseGrand Robust is easy to process. On account of the low fines content, HanseGrand Robust achieves a good water management and a minimum of dust development. It is no longer a problem anymore to park or drive on road shoulders.

With a grain size 0/11 mm and an installation weight of 2.00 t/cum, HanseGrand Robust can be processed conventionally. HanseGrand Robust is placed in a thickness of 4 cm (80 kg/sqm) on the gravel substrate and is dynamically compacted (vibrator, vibratory roller). Placing gradient 2 to 3 per cent.

 

HanseGrand Robust pluS is the problem solution against erosions on gradient sections. By using the stabiliser with a stabilised HanseGrand aggregate, installation of gradients of up to 17 per cent is possible with professional profiling and water management on car parks, paths and especially in road
shoulder areas.
