What application rates per square metre would be recommended?

The application rates will be determined from the final soil indicators as mentioned above followed by a testing matrix to determine the best mix design in terms of durability and tensile strength as well as economics.

We would look at the indicators and draw a lab testing matrix for your lab to conduct and base our final mix on the results. This is also standard practice for pavement design, and in terms of the laboratory a fairly simple and cost effective exercise.
