Description

Phase III –Tender Evaluation of Contractors and Supervision of Construction.
The project ultimately provided for the rehabilitation of the entire road EN223 (now N304), approximately 162km in length from EN103 (now N7) near Mussacama in the south to Colómuè in the north on the border with Malawi near Dedza, all in the Tete Province of Mozambique. The works involved:

  • Breaking up the existing surface and combining sufficient imported sub-base quality material to make up any deficit and to achieve an acceptable vertical profile.
  • Cement stabilised the reworked sub-base to form a 150mm thick layer to a C4 specification.
  • Import and compact 125mm crushed stone base to G2 specification.
  • Surface with a two-coat surface dressing over the trafficked carriageway and a single seal on the shoulders.


In the few areas where the existing selected sub grade and sub-base failed to meet the G9 and G7 specification respectively, the pavement was strengthened to achieve the following design:-

•    125mm G2 Crushed stone base
•    150mm C4 Cement stabilised sub-base
•    150mm G7
•    150mm G9

CPG provided Highway, Bridge, Materials, Pavement, Contracts and Traffic Engineers, Transport Economist, Sociologist and Environmentalist for Phases I and II.

For Phase III Resident Engineers, Bridge and Materials Engineers, Materials and Laboratory Technicians, Surveyor and Inspectors of Works were provided.
