Polymer modified bitumen


What is the product?

Polymer modified bitumen is bitumen (see bitumen for road construction product sheet) whose physical properties are changed by adding new polymers with the aim of improving one or more properties such as skid resistance, rheological characteristics, behaviour after ageing, etc, …

Product Applications

Polymer modified bitumen is used as a binder for asphalt mixtures. It is mainly used in discontinuous top layers. The use of polymer modified bitumen contributes to making the asphalt mixture less sensitive to fraying (= aggregates coming loose from the asphalt pavement) and rutting.

What does Copro do?

  • An inspection of the production unit four to eight times a year, depending on the production quantities.
  • Random sampling at the production unit. Monitoring internal tests of these samples and performing control tests in accredited external laboratories.
  • Verification of the results obtained by the producer within the framework of internal FPC.
  • Inspection of the laboratory used by the producer for FPC.

How do you recognize a certified product?

  • The COPRO mark is present on the delivery note accompanying the delivery of the polymer modified bitumen.
  • The 8-digit quick code on the delivery note, based on which the product sheet can be found on the COPRO Extranet (
