Bleeding treatment

Surface dressings are making a comeback in the maintenance policies of a number of road networks – along with the phenomenon of bleeding. The only technique to permanently remove the excess surface asphalt without adding material is hydroblasting.

Treatment aims

  • Restore wearing course grip.
  • Extend the lifespan of the pavement.
  • Prevent the risks of asphalt pick-up by tyres during very hot periods.
  • Treat only bleeding road sections.

Key figures

  • Over 1,000,000 m2 of bleeding sections already treated
  • Work carried out in over 30 french departments
  • 5 000 m2 of surface treated per machine per day
