Yes, it is well-suited for highways and roads carrying heavy traffic due to its high-temperature performance characteristics.
What Is PG 70-10 Bitumen?
PG 70-10 is a Performance Grade asphalt binder specified by ASTM D6373 based on field temperatures rather than lab hardness. The “70” indicates the maximum 7-day average pavement temperature (°C) it can withstand, while the “-10” is the minimum pavement temperature at which it remains flexible.
A dynamic shear modulus of at least 1.00 kPa at high temperature and 2.20 kPa after aging is what qualifies this grade to resist rutting under sustained heat and heavy axle loads — which is why PG 70-10 is positioned for hot, moderate-cold regions rather than areas with harsh winters.
This classification — governed by ASTM D6373, D4402, and D92 test methods — enables engineers and procurement teams to specify an exact performance binder for road construction, highways, and pavements exposed to high temperatures and heavy traffic loads.
