Fire-Retarding Asphalt Pavement for Urban Road Tunnels: A State-of-the-Art Review and Beyond

Fire Technology, Год журнала: 2024, Номер unknown

Опубликована: Март 19, 2024

Abstract With the rapid urbanization and development of metropolises, urban road tunnels have been constructed at an increasing rate, significantly alleviating traffic pressure, improving resilience. Fire hazards become a major threat to modern due growing popularity electric vehicles high-density transportation goods, particularly flammable materials. Asphalt pavements, as essential component tunnels, may release harmful effluences smoke under high temperatures, exacerbating fire adding risk life safety. It is hence critical investigate fire-retarding asphalt materials their potential use in pavements. This paper provides comprehensive review pavements for tunnel The covers generation mechanisms, evaluation methods, flame retardants recent developments retardant technologies. By investigating these aspects, this aims better understand flammability mixtures promote research flame-retardant technology, ultimately reduce damage loss caused by accidents. Additionally, study identifies limitations current outlook future contribute resilience structures longer service pavement semi-closed tunnels.
