BITUMEN PG 64-22
PG grades are divided into two types:
Modified Bitumen
Unmodified Bitumen.
To differentiate between the two types, we add the low and high temperatures of the PG bitumen. If this sum is greater than 92, the PG bitumen is considered to be polymer-modified. For instance, a PG 76-22 is a polymer-modified binder as the sum is 98. On the other hand, a PG 64-10 is an unmodified binder, since the sum of 64 and 10 is equal to 74. In general, the grades listed in the dark part of the table are considered to be modified bitumen. When the difference between the high temperature and the low temperature is more than 92 degrees Celsius, it is necessary to use a modifier, which increases the price of bitumen. Performance Grade
