The benefits of modified asphalts

The UTI “Rule of 92” gives an indication of whether a binder is modified. If the UTI is less than 92 degrees Celsius, the asphalt binder is probably not modified. Most binders with a UTI value of 92 are modified, but a few crude sources may meet the value without modification. If the UTI is greater than 92, the binder is probably modified.
