Bitumen Durability Factors explain why some roads last for decades while others fail early. These factors include stable chemical composition, proper penetration grade, the right softening point, and strong compaction during construction. Because oxidation, moisture, and UV radiation slowly damage bitumen, durable pavement must keep a balance of hardness and flexibility while holding a strong […]
The main difference between Bitumen 60/70 vs 80/100 is that 60/70 is harder, stronger, and better for hot climates, while 80/100 is softer, more flexible, and better for cold or moderate climates. Bitumen 60/70 resists rutting and deformation when temperatures rise, making it ideal for highways and heavy-traffic roads. Meanwhile, Bitumen 80/100 bends more easily […]
