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 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.
