Contribution to environmental protection and sustainable development
Concrete road pavement has a long service life, which saves raw materials and therefore contributes to sustainable development.
During the operational phase, the concrete road pavement in a tunnel requires less maintenance and repair and reduces energy consumption (electricity lighting).
Concrete resists car fuel: an accidental spillage of fuel does not damage the pavement. Dangerous products can be directly drained into gutters built for that purpose.
At the ultimate life stage, concrete pavement can be recycled into aggregates to be used for road layers or new concrete.
