Road Construction and Roofing




For road construction and roofing Clariant offers a broad range of waxes:

Bitumen, used for road construction or roofing has to be modified to achieve or improve the following properties:

    • lower tendency to form wheel tracks
    • good deforming resistance at high temperatures
    • improvement of the adhesion of the bitumen on the mineral
    • high compacting degree during construction (lower void content)
    • considerable decrease of transport and paving temperature
    • reduced heat radiation and vapour generation
    • energy-saving production of mixed materials; short mixing time
    • protection of wearing parts during production of mixed mineral
    • reduced viscosity and increased softening point of bitumen

Clariant offers the following opportunities for bitumen modification:
    • Additive modification for low temperature pavement in mastic asphalt and rolled asphalt
    • Polymer modification for elasticity and improved cold flexibility
