Paper by ROBINET from ISCR 10th 2006 Brussels Belgium
The concrete road technique has been used for many years for the creation or improvement of roads in land reparcelling project areas. The designs used for these roads have had to develop for a variety of reasons: 1. Vehicles are becoming increasingly heavy. Semi-trailer rigs carry crops directly from the field to the factory. This practice gives rise to greater loads and subjects road structures to more fatigue. 2. A desire to integrate rural roads into the landscape and take account of slow-moving users (pedestrians, cyclists). Two types of road were constructed in concrete in the Lincent reparcelling area: 1. a relief road with a width of 6 m built with dowelled slabs, prior to its construction the underlying clay was stabilized in-situ to a depth of 30 cm with lime and cement so that it could serve as a sub-base. This road relieves the centre of the town of Hannut. 2. various roads used largely for agricultural purposes. These were constructed as two adjacent strips of concrete, i.e. two tracks in concrete with a width of 110 cm each separated by 80 cm of soil on which grass is encouraged to grow. The result is satisfactory integration into the landscape while maintaining accessibility in all conditions even for factory vehicles travelling at limited speeds (30 to 40 km per hour).
