BITUME BLOCK (100/40) (110/30)

Asphalt is treated by blowing air through it at elevated temperatures about 250°C to 300°C to increase physical properties with an exothermic oxidation reaction. BITUME 100/40 is composed in two numbers, 100 is the softening point value with the ring and ball method (in °C) and 40 is the penetration value at 25°C (in 1/10mm). Maximum temperature for use 250°C. BITUME 110/30 is composed in two numbers, 110 is the softening point value with the ring and ball method (in °C) and 30 is the penetration value at 25°C (in 1/10mm).

Product is generally used in roofing for membrane bonding (hot mopped technique). BITUME blocks must be heated before application in a boiler with a maximum temperature of 250°C. BITUME being a bad heat conductor and is more viscous than most other common fluids, product may take time to reach a stable temperature. Avoid localised overheating which could ruin the product, causing a development of coke and a diminishing of thermal exchanges Pour BITUME Block with appropriate tools (bucket, etc) and spread it out with a metal scraper.

BITUME 100/40 is packed in loafs of about 25 kg, wrapped with fusible plastic film. BITUME 100/40 can also be delivered in its liquid form by means of 24 tons per truck. BITUME 110/30 is packed in loafs of about 25 kg, wrapped with fusible plastic film. BITUME 110/30 can also be delivered in its liquid form by means of 24 tons per truck.
