Bitumen PG 82-10

Bitumen PG 82-10 is PMB PG Bitumen which is graded based on its performance at different temperatures. Bitumen Performance Grade is a type of bitumen which is graded according to its performance at different alternating temperatures.

There is a tendency to divide PG grade into two divisions of high-temperature and low-temperature pavement services. Here comes the major issue for high-temperature performance which is rutting, that normally takes a while to amass. Thus, the temperature is measured within a week and the highest is considered to be the high climatic temperature. On the other side, there is a possibility for thermal cracking at low temperature.

Application of Bitumen PG 82-10

Bitumen PG 82-10 use for road construction in heavy traffic roads and airport asphalt layers.

Using SBS to modify bitumen has some effect on bitumen performance as:

Increase HMA stiffness at high service temperatures
Increase HMA elasticity at medium service temperatures to resist fatigue cracking
Decrease HMA stiffness at low temperatures to resist thermal cracking

Higher rigidity

Increased resistance to deformation

Increased resistance to cracks and stripping

Better water resistance properties

High durability
