A paving binder classified by resistance to flow, primarily at 60°C, with additional testing at 135°C. The VG designation is not interchangeable with a penetration grade without checking the complete specification. Share the specified VG grade and the mixing and laying requirements in your project documents. Compare the complete test limits, packaging and delivery conditions when reviewing an offer.
Reference limits from the SRNT catalogue, not measured batch results or a COA. Availability, the applicable standard edition and contractual limits are confirmed for each enquiry.
