The difference between VG10 and VG-30 bitumen is in their viscosity level. Bitumen VG30 is more viscose than bitumen VG 10 and as a result, performs better in road construction in hot regions.

VG 30 or 60/70?

VG30 bitumen seems just like penetration grade 60/70; however, its physical properties, viscosity range, and performance is completely different.

In many applications, particularly road construction, VG30 bitumen is proven to work more efficiently than pen grade bitumen 60/70 at various temperatures. VG30 bitumen can be recognized from bitumen penetration grade 60/70, only with reference to standardized test results. To make sure that you are not buying bitumen 60/70 instead of VG30 bitumen, we recommend you to control the test results carefully and see if the absolute viscosity and penetration value of your bitumen is in range (VG 30’s absolute viscosity should be 2400 poises and penetration value should be between 50 and 70). We not only control the test results of VG30 but also measure the properties of bitumen drums before loading. In cooperation with SGS inspectors, we do an extremely careful sampling and testing of VG30 bitumen and send the results to our clients.
