Alternative Surfacing for Steep Hill Sections in Ghana – Phase 2: Final Design Report
This project on steep hill road sections is investigating the suitability of alternative surfacing on steep gradients of low-volume (feeder) roads
Abstract
This project on steep hill road sections is investigating the suitability of alternative surfacing on steep gradients of low-volume (feeder) roads in Ghana. This is the final design report, which provides details of the research activities undertaken during the final design stage of the project. The main objective of this report was to finalise the research matrix of alternative surfacings, and to present the final designs, drawings, construction procedures and initial construction costs of all road pavement options to be constructed and monitored on demonstrations sections with steep hill gradients ranging from 12% to 22%. A total of 12 pavement types with 5 alternative surfacing (stones of approximately 150 mm in size, interlocking block paving, cold mix asphalt, thin mesh-reinforced concrete and roller-compacted concrete) were designed for demonstration purposes.
This work is part of the Applied Research on Rural Roads and Transport Services through Community Access Programmes in Africa and Asia (AFCAP2 and AsCAP)
