What is the melting temperature of tar used on an airport runway?

There are a number of different asphalt mixes with different melting points. Which mix is used will depend on the location of the airport and the regions expected temperature range.
Some mixes can get very soft at 100 F, but can handle frigid temperatures without going brittle... while others can remain resilient all the way past 130 but would break up like peanut brittle at freezing temps.

What is an airport runway used for?
An airport runway is used for a plane when it goes up in the air and when it goes down on the ground. I would have to agree
Did the temperature fluctuate while the is melting?
No. The temperature does not change during the melting process. All of the heat energy is used to break the bonds of the solid to form a liquid, i.e. the energy is used in the phase change, and thus is not used to raise the temperature.
Why is tungsten used instead of nichrome in bulbs?
higher melting temperature
How long is the longest run way in the world?
Runway 14/32 at Qamdo Bangda Airport is the longest publicly used runway in the world, at 5,500 m (18,045 ft) (or 3.42 miles). Located in Bangda, Qamdo, Tibet, it is the highest airport in the world, at an elevation of 4,334 metres (14,219 ft) and so needs a long runway due to the lack of air density.
What cannot be used to identify a type of matter color temperature melting point or density?
Temperature can not be used to identify a type of matter
What is a crusible used for?
Crucibles are used in laboratory for calcination, melting, high temperature reactions, evaporation.
Why is a stirrer used when determining melting point of a solid?
The stirrer is used to homogenize the sample and his temperature.
Why is Mercury used in thermameter?
Mercury's melting point is close to the room temperature, so it is a good indicator of temperature around room temperature.
Why does the temperature become constant at the point of melting till the whole substance of a solid melted?
That happens because any heat that is added to that melting material will be used to cause further melting, until there is nothing left to melt, at which point the added heat can raise the temperature. A solid melts at its melting point; it does not get hotter than the melting point without melting, that's why it is the melting point.
Relation between melting temperature and sintering temperature?
The idea of sintering is heating a powder until it is hot enough to stick to itself, then reshaping it and letting it set. The temperature used is always lower than the melting point of the material.
Why tungsten wire used in domestic wiring and why?
because tungsten is a high melting point and its melting temperature so high and long life
Under what conditions heat can be given to a substance without raising its temperature?
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
