6.6.4 Slope Protection
If required, placing of topsoil and planting of vegetation on the slopes of embankments should take place in order to minimise erosion before indigenous vegetations can establish roots.
Planting of vegetation for protection of slopes against erosion can be an option.
Where grass or other vegetation is planted for protection of slopes, it is absolutely vital that professional advice to be obtained from a botanist. Failure to do this could lead to intrusion of non- indigenous species that could threaten the environment or cause damage to local farming. The slope can also be protected when using RoadCem and Cement.
6.7 Management and Maintenance Issues
Maintenance currently constitutes one of the major preoccupations of roads agencies in many countries. In the early stages of road development, most of the road expenditure is spent on construction. However, as these networks have become more developed, the expenditure required for adequate maintenance and rehabilitation has increased relative to that required for new construction.(Figure 6.24)
Figure 6.23 Historic path of road infrastructure investment.
With RoadCem it allows a reduction of investment on building,maintenance. It increase, the investment on the new roads further extending the road infrastructure.
Unfortunately, for a variety of reasons, including lack of adequate funding, provision of satisfactory, road maintenance still remains an elusive goal for a number of countries. As a result these countries have paid a high price in terms of deteriorating road networks, very high transport costs and the reluctance of donors to assist with the funding of new or rehabilitation projects. Fortunately, roads agencies are beginning to tackle the maintenance challenges in a more holistic manner to improve efficiency and effectiveness and to achieve sustainability.
