Paving bitumen 40/50

Penetration 40–50 — the hardest grade, rut-resistant for heavy-load routes

Penetration-grade bitumen 40/50 — the hardest grade in our range, imported from trusted refineries in the Middle East, Singapore and South Korea. With a high softening point and outstanding thermal stability, 40/50 is the first choice for heavy-load pavements in Vietnam's hot and humid climate. Bulk supply for asphalt plants and key projects with an end-to-end logistics chain: heated storage, hot tanker trucks and on-schedule delivery.
