STRATEGIES FOR PROMOTING THE USE OF CONCRETE PAVEMENTS IN TANZANIA: TECHNICAL AND INSTITUTIONAL CONSIDERATIONS

Abstract

High-type roads in Tanzania have been predominantly of asphaltic concrete construction. This ever enlarging and
ageing asphaltic road network represents increasing resource requirements on the road agency in the form of
maintenance. Limited resources coupled with the ever sky-rocketing costs of petroleum products and the competing
demands of social economic developments, presupposes the need to look for alternative road construction technology
that is more cost-effective and resource optimising. Experience gained from developed and some developing countries
where concrete pavements have been widely used suggests the potential of this type of pavement in many developing
countries. This paper discusses the technical aspects of design and construction- and maintenance-related aspects of
concrete pavements. The discussion extends further to highlight issues pertaining to the performance of concrete
pavements and strategies for promoting the use of concrete pavements in Tanzania. Conclusions and recommendations
are made with suggestions on how to start implementing the proposed strategies.
