1.1 General
Introduction Via-e-Vita
PowerCem Technologies, The Netherlands, is a company that produces a range of products which are used as additives and improvers of Cement for different applications. One of the products is known as RoadCem and is a product primarily used in road construction. RoadCem is an additive and cement improver, used in soil and other material stabilization typically for road construction. It can also be used in all kinds of other soil stabilization works such as dike construction or landfill lining and similar applications. RoadCem and other PowerCem Technologies products have been used on demonstration and full scale projects in many countries on 4 continents.
This Manual is aimed at all our distributors and other users of our RoadCem product. The builders, contractors, governments, scientists and other interested parties are all welcome to use the Manual.
The Manual is based on experience gathered from different work and research projects we have carried out throughout the world and it explains WHAT RoadCem is, HOW a RoadCem design can be made and how RoadCem is (and can be) applied in practice.
Special consideration has been given to the fact that throughout the world there are different requirements and demands for roads and the approaches and methods used for their design. We have taken cognizance of these different requirements and try to cater for a generic, non location specific approach. This approach can fit within the particular requirements of any given location and or country and standard system.
Traditional road design and construction has proven to be very material and energy intensive. It demands also import and export of enormous quantities of virgin material in order to be completed successfully. This is especially true in situations where the load bearing capacity of base soils is low or when other geotechnical conditions along the route of the road are not suitable.
As a result there are multilayered designs and structures based on imported gravel and/or other acceptable material often exceeding 100 cm in thickness. The traditional designs typically consist of different layers such as the Surface course, Base course and Sub base course (Figure 1.1). These layers are all typically made of imported materials.
