Opinion: Innovations in ecofriendly pavement solutions

While traditional road construction methods have been effective, the pressing need for environmental sustainability has driven the emergence of innovative solutions. Today, governments, research institutions and civil engineering practitioners are collaborating to reimagine road construction through the lens of eco-friendliness and durability. This trend is now evolving in South Africa, with the South African National Roads Agency (Sanral), a pioneer of these initiatives through its research panels.

This paradigm shift is well-rooted in the growing awareness of resource depletion, carbon emissions and climate change. Sustainable materials such as recycled aggregates, bio-based binders and alternative asphalt mixtures are taking centre stage globally, offering promising solutions for mitigating environmental impact while maintaining road performance standards.
