For example the dependence of a traditional road construction approach on imported material requires large amounts of gravel. This creates borrow pits with huge impacts on the environment (Figures 5.11 and 5.12)
Table 5.4 gives a summary of the negative aspescts of the use of traditional materials. In contrast to this the RoadCem method does not rely on imported material and these impacts are therefore avoided.
Table 5.4 Negative aspects of the use of traditional materials.
- Permanent loss of natural resources.
- Loss of wilderness and forest.
- Displacement of species and habitats.
- Loss of potential prodouctivity of agricultural land.
   Material resources
      Morphological damage
  116
- Modification of the natural drainage.
- Increased soil erosion and siltation of watercourses by
disturbance of soil.
- Destabilisation of slopes.
 Ecology
      Pollution
- Contamination of water and soil by fuel and oil spillage.
- Generation of dust during the processing, loading and
transporting of materials.
- Increased dust generated by vihicles along access tracks.
- Littering.
      Social and health impacts
- Creation of habitats for disease.
- Landscape alteratioin and interference with natural beauty.
- Bisection of communities or farms.
- Loss of land legacy.
- Loss of antiquities, cultural heritage, areas of cultural concern
(e.g. graves).
- Hazards to pedestrians and animals, including open or
inmarked trial pits, demarcation beacons, etc.
- Safety risks to local population by exposure to heavy plant
and traffic.
- Noise of drilling, blasting, traffic and plant.
