Hot and Cold Bitumen Processes

to keep flowability and pumpability

Cold recyclers are used to skim the old road surface and apply a new surface simultaneously. The skimmed material is then recycled. To achieve a homogeneous surface finish, hot Bitumen is added to the process.  b Due to the varying width of the working surface, the feeder hoses need to be flexible and up to 5 m long.

Keeping Bitumen Flowable at 180°C
Bitumen is used in road construction for asphalt overlays and to repair road damage. It is also used in joint and sealing technology for concrete and asphalt surfaces. Hot asphalt installation is a highly automated process in which heated pressure hoses are used to keep the bitumen at 180 °C. Without heat tracing, bitumen would loose its flowability and pumpability, causing damage to machines, pumps and dispensers.
