Asphalt preservation with the
READ BARS system

Bitumen Asphalt Regeneration System (BARS)
Substance maintenance on asphalt roads

  • highways
  • federal roads
  • country roads
  • city streets
  • Special constructions (OPA)
  • special routes


BARS bitumen asphalt regeneration system

  • reactivated
  • protects
  • sealed
  • Sustainable preservation of substance


The BARS system is not suitable for

  • profile compensation
  • pothole repair
  • joint filling
  • For larger grain outbreaks


Asphalt surfaces on our roads are subject to wear and tear. The bitumen in the asphalt wearing course ages and becomes brittle over the years due to oxidation, temperature and UV exposure.

This leads to damage such as loss of bitumen, cracking, network cracks and grain loss in the asphalt surface.

Then it is time for the asphalt sealing and regeneration of the bitumen. In order to protect these asphalt wearing courses from further destruction, decomposition and wear

READ this fuel-inhibiting BARS system developed.


BARS - Bitumen Asphalt Regeneration Rejuvenation System


  • reactivated
  • protects
  • sealed
  • Sustainable preservation of substance


The result is a significantly longer remaining service life, combined with a reduction in road maintenance due to the increased resistance of the bitumen present. Prevention instead of repair!

BARS is also particularly suitable for OPA coverings provided with noise-reducing properties when used in good time.

Installation and material composition

The installation is carried out using a special installation device up to

20,000 sqm hourly output and a suspension tailored to the asphalt surface, release after approx. 3 hours.


  • Highly modified binder
  • fuel retardant
  • reactive component
  • Special additional additives

Advantages of the BARS system

  • Net crack sealing prevents the incipient release of fines
  • Cover seal against the ingress of water - here frost and dew
  • Increasing the existing binder quality
  • Extending the useful life of roads
  • can be applied to any asphalt surface. (Can be on any top layer
  • be applied)
  • repeatable several times (4-8 years)
  • Significant increase in road service life
  • significantly lower demand for raw materials compared to other conservation measures

Special features

  • Energy-saving, climate-neutral due to cold installation
  • Installation is carried out with a special device
  • High hourly output
  • Mobile construction site
  • Approval for traffic after 2-3 hours
  • Result

Commercial features

  • Positive price-performance ratio
  • Fast
  • Economically
  • Substance-preserving

  • highways

    Grain breakouts are significantly reduced.

  • City, state and federal roads

    Rehabilitated roads are immediately preserved for many years by asphalt preservation with the LIESEN-BARS system.

  • Test and race tracks

    Racetracks and test tracks in the automotive industry are exposed to extreme stress.

  • airports

    Airstrips and landing strips are also exposed to particularly high loads. The asphalt surface must therefore meet special requirements.
