THE INNOVATORS IN SURFACE PREPARATION

Airport applications Today’s busy international airports handle ever increasing levels of traffic and the turn around times for aircraft are becoming ever shorter. Modern airport runways have to be capable of safely landing turbojet aircraft with their greater weight and high landing speeds. The braking performance of pavement surfaces has become far more critical and under certain conditions, hydroplaning or unacceptable loss of traction can occur, resulting in poor braking performance and possible loss of directional control. Runway surface condition is therefore critical to the safety of...

THE INNOVATORS IN SURFACE PREPARATION Biggest benefits • All BLASTRAC techniques are purely mechanical, and therefore very clean • None of our technologies are using chemical substances of are wasting valuable drinking water • Perfectly clean (closed circuit precess, no waste to dispose) • Safe (no risk of underground deterioration by the process itself or by frozen water, no damage on built-in lightning devices • Very fast evacuation of the airfield if necessary • Permanent control can be made through grip testing devices / CFME (Continuous Friction Measuring Equipment) • Can prolong the...

Surface texture There are principally 3 types of texture which are important factors in the performance of a runway surface, Megatexture, Macrotexture and Microtexture. In addition to these the terms Negative texture and Positive texture are often referred to, these are types of Macrotexture and more to do with the method used or type of material laid. Megatexture is a component of surface profile, how flat the surface is. Poor megatexture increases the demands on the suspension, causes vibration to the aircraft structure and gives an uncomfortable ride, it causes patchy drainage and water...

THE INNOVATORS IN SURFACE PREPARATION Maintenance Microtexture the Microtexture of a surface is provided by the roughness or texture of the surface of the individual aggregate particles. Microtexture is the fine component of surface texture formed by the tiny interstices on the surface of the aggregate particles. It is the main contributor to providing grip or skid resistance with the tyre, particularly at low speeds. Microtexture is measured by PSV using the British Pendulum Tester or by mobile methods such as the Griptester or ASFT Aggregates used in asphalt surface courses will typically...

Scheduling runway friction surveys The table below can be used as guidance for scheduling runway friction surveys. As airport operators accumulate data on the rate of change of runway friction under various traffic conditions, the scheduling of friction surveys may be adjusted to ensure that evaluators will detect and predict marginal friction conditions in time to take corrective actions. runway friction surveys Number of daily minimum turbojet aircraft landings per runway end minimum friction survey frequency Research has shown that visual evaluations of pavement friction are not...

THE INNOVATORS IN SURFACE PREPARATION (1) When the average texture depth measurement in a runway zone (i.e., touchdown, midpoint, and rollout) falls below 0.045 inch (1.14 mm), the airport operator should conduct texture depth measurements each time a runway friction survey is conducted. (2) When the average texture depth measurement in a runway zone is below 0.030 inch (0.76 mm) but above 0.016 inch (0.40 mm), the airport operator should initiate plans to correct the pavement texture deficiency within a year. (3) When the average texture depth measurement in a runway zone (i.e., touchdown,...

Blasting to remove rubber and improve surface texture The basic blasting process has been around for over 100 years and Blastrac was the inventor of the first mobile shot blasting process in the early 80’s. Blastrac are now the undisputed global leader in this field. Operating in over 80 countries the Blastrac product range now has some 65 machines, from handheld products to truck mounted and fully remote controlled blasters. The Blastrac system is a mechanical process which is designed to remove surface contaminants, surface imperfections and coatings. The process is fully controlled, safe...

THE INNOVATORS IN SURFACE PREPARATION BLASTRAC MACHINES ^BLASTRAC There are several blast machines suitable for both rubber removal and retexturing of airport runways, these include: BLASTRAC 2-20DT WWW.BLASTRAC.EU • INFO@BLASTRAC.EU

AIRPORT REFERENCE LIST ^BLASTRAC Blastrac equipment has been used extensively at international airports throughout the world for: ■ rubber removal ■ line & Markings removal ■ improving texture & skid resistance. ■ surface preparation prior to sealer application. recent examples include: ■ Maputu airport / Mozambique ■ Tulsa Airport / Tulsa - Oklahoma / USA ■ Las Vegas Airport / Texas / USA ■ Roissy / Charles de Gaul / Paris / France ■ Tours military Airport / Tours / France ■ Airport Point a Pitre / Guadalope / French oversees region ■ Monte real military airbase / Portugal ■ Pau Airport /...

THE INNOVATORS IN SURFACE PREPARATION The shot blasting process provided by Blastrac equipment has significant benefits when used for rubber removal and surface retexturing of airport runways. the system can effectively remove rubber deposits without the need for water, solvents or chemicals. the process is dry, enclosed and removes all debris from the surface, leaving a clean dry surface ready for immediate use, or for application of sealers or coatings/lines. Removed material can be recycled at asphalt or concrete production factories. the Macrotexture can be significantly improved...
