Jordan Performance Grade Map | Ministry of Transport

What is this map?

This map presents the Performance Grade (PG) classification of asphalt binders across the Hashemite Kingdom of Jordan, derived from statistical analysis of long-term climate data recorded at weather stations throughout the country. PG grading — a core component of the Superpave system — specifies the binder grade required to withstand the full range of temperatures a road surface experiences at a given location, ensuring pavement durability and performance under local climate conditions.

How to use it?

Click on any coloured zone to view its assigned PG grade, geographic coordinates, and elevation. Use the layer control panel in the top-right corner to switch between base maps, or to show and hide individual layers — including the Jordan boundary, weather station locations, and PG grade zones. Engineers and planners should use the displayed grade as the minimum specification for asphalt binder selection in any road construction or rehabilitation project within that region.
