The general purpose of this document is to provide guidance on the selection and use of road construction materials and, in doing so, make a contribution to reducing the costs of constructing, rehabilitating and maintaining road infrastructure, and vehicle operations.
This report can be viewed as the first stage in the provision of a companion document, or series of documents, to Overseas Road Note 31 (which provides guidance on the structural design of sealed roads within tropical regions). It also seeks to raise and promote discussion on key selection and utilisation issues within its overall objective.
