Penetration Grade Bitumen
it is a kind of bitumen classified due to its hardness and consistency which determines the degree of penetration. As the penetration increases, the bitumen becomes softer. This kind of bitumen, also known as PEN grades bitumen, is used typically for road construction & paving goals. The amount of penetration is determined via its penetration test in the laboratory using a special needle at a temperature of 25 degrees Celsius.
The most common penetration grade bitumen types are 30-40, 40-50, 60-70, 80-100, 85-100. Each of these grades is suitable for a specific condition considering various factors particularly temperature, traffic, and geotechnical features.
Having been too soft or hard, the bitumen possibility of cracking or deformation increases, hence the importance of using an appropriate choice regarding the climate condition, is obvious.
As it is somehow clear, the soft bitumen performs better in cold weather and the hard one works better in hot climates.
Bitumen 40-50
Bitumen 40/50, like other PEN grades, made by air flowing process and used for road construction and also asphalt pavements, yet in tropical regions.
Bitumen 60-70
This grade of bitumen, is produced through air blowing process in a refinery.
60-70 bitumen is considered as a mild PEN grade while it enjoys adequate durability exposing to heavy traffic loads.

Bitumen 80-100
Being categorized under the semi-soft grade of bitumen, 80-100 grade is an appropriate choice for cold weather. This is almost the most favorite PEN grade bitumen widely targeted in some African countries such as Kenya.
