Improved safety for people and structure
Active measures (ventilation, smoke extraction, alarms and detection) are contributing factors to fire safety in tunnels. However, the best passive measures should also be considered such as the use of totally incombustible materials, concrete being one of those materials.
In case of fire, concrete pavement has good performance characteristics facilitating road users' self-evacuation and rescue team's arrival. Thanks to its purely mineral composition, concrete is an inert, stable and non-flammable material and is therefore classified as a material with a high fire safety factor.
