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 andageing asphaltic road network represents increasing resource requirements on the road agency in the form ofmaintenance. Limited resources coupled with the ever sky-rocketing costs of petroleum products and the competingdemands of social economic developments, presupposes the need to look for alternative road construction technologythat is more cost-effective and resource optimising. Experience gained from developed and some developing countrieswhere concrete pavements have been widely used suggests the potential of this type of pavement in many developingcountries. This paper discusses the technical aspects of design and construction- and maintenance-related aspects ofconcrete pavements. The discussion extends further to highlight issues pertaining to the performance of concretepavements and strategies for promoting the use of concrete pavements in Tanzania. Conclusions and recommendationsare made with suggestions on how to start implementing the proposed strategies.
