The Mount Edgecombe Interchange Upgrade received the 2017 Fulton Awards winner for the “Infrastructure” category.
Awarded by the Concrete Society, South Africa’s largest interchange with its wide use of finishes, techniques and elements is a well deserved choice as the 2017 Fulton Awards winner in the “Infrastructure” Category.
Conchem Construction Chemicals are proud to have been associated with this project as one of the main suppliers of construction chemicals used in the project.
This project showcases the use of concrete in civil engineering infrastructure in that it encompasses 9 new road bridges, 1 new pedestrian bridge, 9 mechanically stabilised earth walls, and 3 soil nail retaining walls.
It featured three simultaneous incremental launches with a combined deck length that exceeds 1.5 km, the longest incrementally launched viaduct in the southern hemisphere, and three incremental launches being constructed simultaneously.
This is a South African first. It was constructed under difficult conditions having to deal with maintaining the requirements of the heavy existing traffic demands within a congested site.
A total of 41 concrete mixes were designed for this project as well as three different grout mixes and two different sprayed concrete (shotcrete) mixes.
