The main purpose of this 'Guideline on the Use of Sand in Road construction in the SADC Region' is to provide practitioners with a good understanding of the properties of one of the most abundant, naturally occurring materials found in the SADC region – sand – so as to facilitate the more widespread use of this ubiquitous material in the construction of low volume roads.
The Guideline comprises seven chapters as follows:
Chapter 1: Provides the background to the project including its
purpose, scope and structure.
Chapter 2: Presents the general characteristics of including their
definition, formation, composition, distribution, geology, origin and
Chapter 3: Outlines the approach to prospecting for sands and discusses
the various tests used to evaluate their properties for design purposes.
Chapter 4: Provides information on the locations of the sand sampling
sites and the laboratory tests carried out and discusses the results, in
terms of the physical, mineralogical, chemical and engineering
properties of the sands.
Chapter 5: Discusses the design, specifications and use of sands in
Chapter 6: Considers various issues related to the construction of
roads using sand.
Chapter 7: Summarises the outcome of the project and proposes the way
