Bitumen 60-70
Road bitumens are classified according to their penetration value and softening point to ensure optimal performance across different climates and traffic conditions. Bitumen 60-70, with a penetration range of 60–70 (0.1 mm) and a softening point of 48–52°C, offers an ideal balance between flexibility and structural strength.
As the most widely used penetration grade in global road construction, Bitumen 60-70 is trusted for highways, airport runways, and urban infrastructure projects. It delivers strong adhesion, high durability under heavy traffic loads, and reliable performance in moderate to warm climates.
Manufactured under strict quality control standards and suitable for bulk, drum, or jumbo bag supply, Bitumen 60-70 is a dependable and cost-efficient choice for contractors, distributors, and infrastructure developers seeking consistent quality and long-term pavement performance in international markets.
