Perspective of the use of road asphalt surfaces in tunnel construction

Popis výsledku v původním jazyce

The construction of road tunnels is nowadays topical issue in the Czech Republic and also abroad. The reasons for their construction are various, including the shortening the length of road, overcoming mountain areas, limiting traffic noise or protecting the environment. With the increasing number and lengths of road tunnels, there is also an increase of extraordinary events that occur in these buildings. Extraordinary events include fires as well. The occurrence of a fire and its expansion in road tunnels is affected by many aspects. One of the influences, that can affect the expansion of the fire and its extinguishment by fire department, is also the type of road surface. Currently, variants of concrete (cement-concrete) or asphalt surfaces are used. From the point of view of fire safety, there is a long-lasting discussion about the suitability of asphalt road surfaces in tunnel construction. The risk is seen in road flammability, in possible release of toxic combustion products, or eventually in softening caused by heat released during the fire. In past years, a number of theoretical and experimental works have been compiled, dealing with the safety of asphalt surfaces in tunnel constructions. However, the results of these works do not present clear conclusions on their safety. The advantages and disadvantages of each type of road and the expected future development are discussed in the article.
