Calcrete - a pedogenic material that commonly occurs in arid and semi-arid regions of Southern Africa – is one of the locally available materials for road building found in Inhambane Province, Mozambique. A project is underway to provide guidance on the location of calcrete deposits as well as on their classification as road building materials and appropriate technical specifications for their use in road construction. This Technical Review presents an extensive review of previous research, experience and studies on the use of calcrete in road construction in the region, along with any existing guidelines, standards and specifications.
