Functional Bitumen PG 70-16

Applications of PG 70-16 Bitumen

PG 70-16 is another PG bitumen designed for use in very hot regions with relatively mild winters. This grade offers very high resistance to rutting and softening under heat, while also maintaining crack resistance in winters that are not too cold. Due to its high viscosity, PG 70-16 requires higher temperatures during asphalt laying and compaction. It is particularly suitable for high-traffic or heavy axle-load projects. Typical applications include:

• Highways, expressways, and main roads in hot climates
• Airports and runways
• Industrial and urban roads with heavy traffic
• Infrastructure projects in hot regions with cool nights

Comparison of Bitumen PG Grades

Bitumen Grade	Performance Range	Suitable For
PG 64-16	+64 / –16°C	Hotter-than-average regions
PG 70-16	+70 / –16°C	Very hot regions with slightly cold winters
PG 70-10	+70 / –10°C	Very hot regions with mild winters
PG 70-22	+70 / –22°C	Very hot regions with cold winters (less common)
