Agreed with all Experts specially With Mr. Yaqoob and Mr. Wolf that each region has a different allowable temperature of asphalt at the time of lying about300 °F (roughly150 °C) for virgin asphalt and330 °F (166 °C) for polymer modified asphalt, and the asphalt cement at200 °F (95 °C).
Mix temperature will be dependent on the grade of asphalt used in the mix. The less viscous the asphalt, the lower the temperatures should be. The more viscous the asphalt, the higher the temperature can be.

is the temperature of the surface of the layer on which the new mix is placed. It is well known that heat in an asphalt concrete layer is lost in two directions. The surface of the mixture cools as heat is transferred to the air.
Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, Cold temperatures can cause cracks as the asphalt contracts.Mixture formulations·
Production and placement temperatures are typically 50° F – 70° F lower than conventional hot mix asphalt. PQ Corporation recommends the addition of 0.25% by weight of the mix, or 5 pounds of Advera WMA per ton of asphalt mix.
The average production temperature of hot mix asphalt is between 150 and 190°C, which depends however on the mixture produced (see below). Different kinds of Asphalt.
