BITUMEN PG
Performance Grade (PG) bitumen is graded based on its performance at different temperatures.It is new method bitumen standard which based on varying temperatures. This method studies the mechanical specifications of bitumen.
Since in this method, a temperature range is defined for bitumen, the consumer can easily choose the desired product.
Performance Grade is determined for polymer modified bitumen and pure bitumen based on environmental conditions and temperature.
The wider PG range the higher resistance and more favorable specifications.
Chemical Mine World has the capability to supply customers a wide range such as PG 46, PG 52, PG 58, PG 64, PG 70, PG 76, PG 82.


Application of Performance Grade (PG) Bitumen:
PG 52-28 is primarily used in paving for both new construction and pavement rehabilitation and in both dense-graded and open graded Hot Mix Asphalt (HMA). This product could also be used for sealing of edges of new to told paving and crack sealing. Other uses include spray applications for bridge deck and pavement protective membrane with fabrics.
PG 58-22 is primarily used in paving for both new construction and pavement rehabilitation and in both dense-graded and open graded Hot Mix Asphalt (HMA). This product could also be used for sealing of edges of new to told paving and crack sealing. Other uses include spray applications for bridge deck and pavement protective membrane with fabrics.
PG 58-28 is primarily used in paving for both new construction and pavement rehabilitation and in both dense-graded and open-graded HMA. Other uses include spray applications for bridge deck and pavement protective membrane with fabrics. PG 58-28 is generally used in very cold areas.
PG 58-34 is generally used in the upper half of eastern Washington and on higher elevation roadways. PG 58-34 is a paving asphalt cement primarily used for the production of Hot Mix Asphalt (HMA). This product could also be used for sealing the edges of new to old paving and crack sealing.
PG 58-34 is used in paving for both new construction and pavement rehabilitation in both dense-graded and open-graded HMA.
PG 58-40 is primarily used on the high elevation roadways. PG 58-40 is paving asphalt cement for the production of Hot Mix Asphalt (HMA).
This product could also be used for sealing of edges of new to old paving and crack sealing.
PG 64-22 is primarily used in paving for both new construction and pavement rehabilitation and in both dense-graded and open graded Hot Mix Asphalt (HMA). This product could also be used for sealing of edges of new to old paving and crack sealing. Other uses include spray applications for bridge deck and pavement protective membrane with fabrics. It has been reported that with proper aggregate characteristics and asphalt content, HMA with PG 64-22 as the binder may exhibit less tenderness than a similar mixture with a lower viscosity/softer asphalt. The typical tenderness problems of mixture shoving and checking during rolling and pavement surface scuffing and marking by traffic immediately after paving may be noticeably reduced.
PG 64-28 is primarily used in paving for both new construction and pavement rehabilitation and in both dense-graded and open-graded HMA.
Other uses include spray applications for bridge deck and pavement protective membrane with fabrics. PG 64-28 is generally used for the Lower half of Eastern Washington.
PG 70-22 is primarily used in high traffic areas and is also the paving asphalt cement primarily used for the production of Hot Mix Asphalt (HMA).
This product could also be used for sealing the edges of pavement and for crack sealing.
