FEASIBILITY OF POZZOLAN-STABILISED PAVEMENTS IN DEVELOPING COUNTRIES
Traditional strengthening methods for roads in developing countries require large quantities of high quality aggregates, or hydraulic binders such as Portland cement, which may have unwanted environmental impacts. Alternative binders, such as natural pozzolanic materials, can alleviate many of these impacts and lead to significant import savings for the countries where these materials originate. Based on experiences from a recent road construction project in Tanzania, and a pilot study relating to the suitability of locally available pozzolanic materials, a research project is proposed to help establish a theoretical model for the structural and functional deterioration of pavements with pozzolan-stabilized bases. The project findings will provide a solid foundation for the design of road pavements in tropical climates with pozzolan-stabilized sand bases.
