Lower CO2 Road Solutions Trial - N52 Meath

To address this challenge, the project team developed innovative low CO2 asphalt materials, for base and binder courses, using the latest technologies available including: 70% reclaimed asphalt, warm mix technology and bio binders. HVO was used in all plant & machinery to further reduce the CO2 impact during production, supply & laying. The compaction rollers used the latest intelligent compaction technology saving time & cost while also reducing carbon emissions. These innovations help to reduce our CO2 emissions without compromising our laying practices. Close collaboration between key stakeholders, including material suppliers, contractors, and testing teams, ensured the successful implementation of the solution. Performance testing was conducted to validate the mixture's ability to meet specified requirements for durability and functionality under high traffic conditions.

To continue to push the boundaries of what’s possible, through innovations in sustainable materials and practices. Further collaboration with key stakeholders to challenge the legislative & regulatory headwinds faced in developing asphalt mixes with Ultra High RAP contents and increasing the use of bio-binders, is crucial in the pursuit of lower carbon road solutions.
