To cope up high temperature of 196°C, the taxi ways and aprons are constructed with
A. Asphaltic concrete
B. Rubberised tar concrete
C. Plain concrete
D. All the above
Answer: Option A
Solution(By Examveda Team)
Asphaltic concrete: This type of concrete is used to cope with high temperatures, such as 196°C. It has good resistance to temperature variations and is commonly used in the construction of taxiways and aprons.Rubberised tar concrete: While it can be used in some applications for its flexibility and durability, it is not typically used for withstanding very high temperatures like 196°C.
Plain concrete: This type of concrete is not suitable for coping with very high temperatures as it can crack or deteriorate under such conditions.
All the above: This option is incorrect because not all listed materials are suitable for high-temperature conditions.
Therefore, to cope with high temperatures of 196°C, the taxiways and aprons are constructed with asphaltic concrete.
why all of above , because asphalt concrete main element is bitumen which burn/ flash point is 170'C.
