Bitumen and asphalt, primarily used for paving roads, are sticky, black and highly viscous or semi-solid oil-based materials.

They are typically stored and transported at temperatures around 150°C (300°F). The tippers carrying asphalt need to be covered properly to prevent heat loss and to protect against rain or snow. In cold climates, asphalt must be additionally protected with a cold-resistant cover which prevents condensation.

Sioen has developed S9350: a special technical textile to protect asphalt and bitumen during transportation.
