Tarmac had launched a carbon calculator designed to be used with its CEVO Asphalts solution, which uses plant-based bio binders, warm mix technologies and higher levels of recycled asphalt planings (RAP) to deliver a lower-carbon product.
For each mix, the tool provides carbon savings compared with a traditional hot-mix asphalt up to the point that the product leaves the asphalt plant. Users can select a bio-binder version to see further carbon reductions if applicable. Figures are based on Tarmac’s internal data, using industry-recognised asPECT methodology developed by National Highways, verified by Tarmac’s carbon experts.
The CEVO Asphalts carbon calculator generates a downloadable certificate, showing the carbon footprint of the material, carbon savings, the date of calculation and methodology used – all of which can be used to demonstrate sustainability in tenders, highlight potential for further carbon savings, and help contractors with their Scope 3 emissions reporting, Tarmac said.
Jess Tuck, national technical director at Tarmac, said: “We’ve already successfully launched CEVO Asphalts. Adding biogenic aggregates to our CEVO low-carbon asphalt toolkit, we can go further with net-zero asphalt. Now we offer an additional tool that promotes transparency, clarity and credibility, showing exactly what customers are specifying. This is key because we all need to be transparent if we are to meet national regulations and testing requirements.
“It’s simple to use, based on reliable methodologies and backed by the industry expertise of Tarmac’s specialist team. Together with our asphalt solutions, we’re confident this will prove a vital resource for those working in highways.”
