Project Objectives/Outcomes

• The upgrading of 34 km of two lane Trunk Road No 8 (Section 6) from gravel road to Class 1 Bitumen standard under EDF financing conditions.
• The 34 km of Section 6 was beyond a fault line and in very different geological conditions.
• The naturally occurring soils were very much classed as ‘problem soils’ which necessitated considerable research to devise a suitable soil stabilisation strategy for the pavement.
• A cement-bitumen stabilised calcrete was used for both base and sub-base, and this was surfaced with a 19 mm chip seal plus a final seal of hot sand-asphalt mix.
