In practice RoadCem will be applied when the designers and implementing agents(consultants, building-contractors, engineering companies) have enough trust in the product and when this can be proved to the users and clients (Government ministries, water authorities, private sector companies).
It is therefore fundamentally important that when a RoadCem based solution is recommended that:
1. User and client requirements are clearly understood.
2. Users and clients have a clear understanding of why a RoadCem solution is a better solution.
Point 2 is of special interest to PowerCem Technologies. The following pages are intended to provide enough information so that the distributors of RoadCem, designers and implementing agents can convince the users and the clients about the advantages of the RoadCem solution.
3.2 Basic Points 3.2.1 General
When making a road design, or better said pavement structure design, certain basic points must be known up front.
The information on these basics can be supplied by the client. If he does not have this information available then it can be found by making use of literature studies or by field measurement and research.
When designing proper road pavements, there is need for information about:
• Soil.
• Traffic load.
• Material properties.
• Construction and design.
Within each of these categories data and information needs are substantial and need to be met.
3.2.2 Soil
Information on the sub-base can be determined from the existing field research reports. These reports should contain information on the grain composition, the bearing strength (the dynamic elasticity module) and the groundwater level as a minimum.
When this information is not available then a tests must be carried out to collect this data and information. (tests are discussed in Chapter 4)
The information/data that is required and must be either extracted from existing reports or by doing field surveys and measurement refers to:
• Bearing strength of the sub-base, the dynamic elasticity modulus.
• Groundwater level.
• Grain composition of the soil (upper 0, 40 meters /surface-soil).
