Also question is, what is the melting point of bitumen?

Bitumen has a melting point of around 240degrees Fahrenheit which is high enough to be safely used forroadway designs and low enough to be heated up without using alarge amount of energy.

Similarly, can asphalt be poured in cold weather? In general, it is best to hold off on paving projectsuntil we have gotten through the winter. However, wecan pave in the winter as long as weatherconditions are dry and the ground isn't frozen. In other words,cold weather asphalt paving can be done during mildwinters or in late fall.

Keeping this in view, how hot is asphalt when it is 100 degrees outside?

Asphalt can be 40-60 degrees hotter thanthe surrounding air temperature. So those common 100 plussummer days can mean we're moving about on a surface as hotas 160 degrees! Obviously, the key to avoiding any burns isto wear shoes or anything on your feet that acts as abarrier.

How does temperature affect asphalt?

The viscosity of asphalt will be affected by theHMA temperature. When HMA temperature decreases, theasphalt cement binder will become more resistant todeformation because it will become more viscous. Basically,temperature – specifically heat – will affectasphalt in a number of ways.
