Abstract
Mozambique is investing heavily in rehabilitating and upgrading the current roadway
infrastructure. Investigation by the Mozambican roads authority found that some
consulting engineers and contractors were not familiar with Mozambican conditions and
materials. The World Bank sponsored a research project to support the roadway
infrastructure preservation and maintenance efforts. The thesis work presented forms an
integral part of the work conducted by the World Bank project research team. The
objective of the thesis is to characterise cement stabilized sand bases in Mozambique
under Accelerated Pavement Testing (APT) in terms of stiffness and deflection
responses under load trafficking. This work forms the basis for developing guidelines for
a mechanistic-empirical design method for Mozambican conditions and materials.
Reported findings from initial MMLS3 testing conducted for the World Bank project were
used to scope the full-scale research study and provided guidelines for the selection and
construction of full scale test sections on natural subgrade. The APT presented
encompass full-scale pavement testing including wet trafficking cycles to emulate
environmental effects.
