color=#000000><FONT color=#000000>I believe you have this wrong. Pitch does not
harden with the application of heat, it softens with the addition of heat. I
believe what you are erroneously referring to is the curing of asphalt concrete.
Cooling of the asphalt results in the hardening of it. However, in the
curing process, the heat</FONT> is prolonged (to counteract the heat loss)
somewhat, so the temperature does not drop too rapidly but in a controlled
manner and not too rapidly and is reasonably uniform throughout the
volume as the asphalt loses heat through its surface to the
environment. In this manner (curing process) the cooling takes place
in a fashion conducive to obtaining optimum hardness of the asphalt. But heating
asphalt will soften it, not harden it. I think I have it right.
