In 2019, Southampton City Council took a decisive step towards environmental sustainability by declaring a climate emergency and committing to the ambitious goal of achieving net zero emissions by 2030.
As part of its Green City Charter, the council has embraced innovative methods to transform its infrastructure while reducing its environmental impact.
One of the standout examples of this commitment is the recent resurfacing of Hinkler Road. As a busy bus route serving local schools and businesses, this project demonstrates how strategic planning and the use of cutting-edge materials can lead to significant environmental benefits.
At the heart of the initiative was the use of Milepave™, a grouted macadam that reduces carbon emissions by an impressive 40% compared to traditional asphalt. The material’s unique properties—lower mixing temperatures, reduced energy consumption, and decreased bitumen content—make it an outstanding choice for eco-conscious road maintenance. Milepave™ is also sealed with a liquid asphalt grout, enhancing durability, flexibility, and resistance to thermal damage.
Innovative Materials for a Greener Future
The Hinkler Road project achieved key sustainability milestones:
- 4,681m² of resurfacing completed
- 58.6 tonnes of AC 10mm material used for road reprofiling
- 15.75 tCO₂e total emissions
Beyond these figures, the project delivered savings of over 50 tonnes in aggregates and seven tonnes in bitumen compared to conventional methods. Additionally, it achieved a carbon saving of 10.63 tCO₂e by using low-carbon materials and partnering with a carbon-neutral contractor.
A Community-Focused Approach
Collaboration was integral to the project’s success. Partnering with Balfour Beatty, the works were carefully scheduled during half-term to minimise disruption to the local community. By prioritising the needs of residents, businesses, and schools, the project not only achieved its environmental goals but also strengthened community relationships.
Building Resilience for the Long Term
In addition to its sustainability benefits, the Hinkler Road resurfacing project was designed with long-term durability in mind. By addressing specific road issues and ensuring lower whole-life costs, the project demonstrates how innovative approaches to infrastructure can deliver both environmental and economic advantages.
This initiative serves as a shining example of how local authorities can embrace sustainability without compromising on functionality or quality. By leveraging advanced materials and strategic planning, Southampton City Council is paving the way – both literally and figuratively – towards a greener future.
