| The District Municipality has a planned programme for upgrading township roads in its 5 municipalities. Previously, the in situ clayey soil had to be cut to a depth of 200mm and spoiled. A 200mm layer of selected aggregate was then imported from a distant and expensive source. As the Municipality wanted to use its own limited road-building equipment and manpower, and reduce costs, it decided to stabilize the in situ soil instead, with great success. The Municipal Roads Dept. is now able to construct a stabilized un-surfaced road of 1 km. in 2 days, which previously took 15 days with the “spoil and import” method and limited equipment. The un-surfaced road instantly provides a safe, less dusty, non-slippery wearing surface in all weathers and the roads are later provided with a side-drain and surfaced with 60mm concrete pavers produced by a local community-operated brickyard. |
