Runways are critical to the safety of the aviation industry; they need to be free from deposits such as grease, rubber and hydraulic fluids.

 

The build-up of the rubber, jet exhaust, hydraulic oil and dirt reduces the frictional qualities of the landing surface, particularly when wet. Lack of surface friction is the major factor affecting the braking of aircraft on a wet runway & it may create problem during landing resulting in accident.


To ensure the highest possible degree of safety during landings and take offs, regular friction tests are carried out by airport staff. When these results show any danger of skidding, it has become the standard practice to remove rubber deposits well before it reaches a critical point, usually on a regular basis. The most popular way is with the use of controlled high pressure water.

 

TO COMBAT THIS PROBLEM, FOLLOWING TECHNIQUES ARE USED FOR RUBBER REMOVAL FROM RUNWAY

  • Ultra-high pressure water blasting
  • Chemical removal
  • High Velocity Impact Removal (Shot blasting)
  • Mechanical Removal

To remove pavement markings & rubber from runway faster and more thoroughly than vis-à-vis other conventional techniques without damaging the road, Ultra-high pressure water blasting is used as it offers following advantages.

  • Completely removes coatings, membranes, thermal epoxies, and rubber build-up…even from grooved pavement
  • Leaves concrete and asphalt undamaged
  • Creates a stronger bond for restriping
  • Eliminates dust and debris, with optional vacuum recovery
  • Saves labor, since fewer operators are needed
  • Won’t expose the environment or operating personnel to abrasive media or chemicals.
  • Reduction of costs due to lesser cleaning cycles
  • Surface protection - no damage to micro and macro texture
  • Environmental care - very low water and fuel consumption; no chemical use
  • Applicability on all kind of surfaces such as asphalt, anti-skid, petro-grip, concrete-grooved or non-grooved
  • Flexible planning and execution of rubber and paint removal independently
  • Selective rubber removal of small areas with insufficient friction values possible
  • Highest availability of runway, taxiway and apron areas because of minimal warning times for area vacation
  • Low waste removal expenses because of low water volumes used
  • Optimal applicability for the removal of markings by best treatment; preparation of surfaces for new painting
  • Universal application of the systems for cleaning of sealing joints, concrete renovation, cleansing of steel and concrete areas, cleaning of apron areas, oil spill removal, etc
