| Abstract: currently asphalt grading in Iraq depend on two types; penetration grade and viscosity grade. These grades did not give impression on asphalt pavement performance because it is depend on fixed temperature test. In this paper Iraq map was developed by using superpave method to find performance grade. High and low pavement temperature was calculated. Contour maps for high and low pavement temperature developed by using geographic information system (GIS). A map presented the temperature zones in Iraq in terms of asphalt performance grade. The data of temperature was taken from 48 weather stations distributed to all region of Iraq. It has been found PG70-10 and PG76-10 covering more than 70% of the parts of Iraq. | ||
