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.
