5.1.2 The benefits of RoadCem method
The benefits of RoadCem method includes:
• lower transport (construction, maintenance and vehicle operating) costs;
• increased social benefits (more reliable access to schools, clinics, etc);
• reduced adverse environmental impacts and health and safety problems.
The above benefits hinge critically on the ability of the responsible authority to maintain the roads to the level of service for which they were designed.
Achieving sustainability in all aspects of road provision is absolutely critical if the world’s long term goals of sustained economic growth and development are to be attained. In the past attempts to achieve such sustainability have failed because one or more of the seven key dimensions (Figure 5.1) have been missing or been inadequate. The result has been that many roads have fallen into disrepair and, consequently, have not only failed to serve the needs of the people and the economy but also often adversely affected the environment in very complex ways.
5.1 3 The 7 key dimensions of sustainability of road infrastructure
There has been a tendency to focus predominantly on the technical and economic aspects of road provision and inadequate attention has been given to other aspects of sustainability in the past. The result has often been a lack of responsiveness to various other requirements and a reduced likelihood of achieving sustainable solutions, even when substantial funding is made available.
The seven key dimensions of a sustainable road system, which should always be observed in the provision of roads are shown in figure 5.1.
