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 […]

Road marking removal

Road signs help to guide users safely and must be consistent, readable and adaptable. Hydroprojection makes it possible to modify horizontal signage while respecting these requirements. Treatment aims Remove all types of floor markings (paint, thermal plastic strips, temporary signs). To ensure wearing course sustainability. Immediate return to service in order to minimise inconvenience to […]

Hydroblasting (Rubber removal)

Safety is a major challenge at airports, and particularly grip on landing strips, which is subject to stringent control by the authorities. Water jetting treatment removes rubber deposits and ensures that roughness levels comply with the standards in force. Rubber removal aims Remove rubber from wheel contact areas. Obtain friction values above the minimum legally […]

Friction measurements

On runways and roads alike, users’ safety depends heavily on the grip level of the surfacing. Constant skidding measurements ensure that airport surfaces remain in good condition. Measurement aims Measure grip levels of airport runways in order to determine their actual Coefficient of Longitudinal Friction (CLF). Analyse measurements and check their compliance with the minimum […]
