Safe landing at Vaclav Havel Airport
TenCate Polyfelt® has been used for rehabilitation work carried out on the runways of Vaclav Havel International Airport in Prague. This material retards crack formation and increases the service life of the pavement.
Prague airport is the most important international airport in the Czech Republic and the biggest airport among the new EU member states.
Airport runways must satisfy stringent demands relating to quality and safety. Runway cracks and uneven surfaces can cause dangerous take-off and landing conditions. After many years of use, the asphalt runway surface at Prague International airport had reached the end of its service life. Not only had cracks appeared due to the continuous rise in loading operations and the increasingly severe weather conditions, but natural bitumen aging (oxidation) had also occurred.
Reason enough for the authorities to launch a surface rehabilitation programme using a reliable and technically sound method: the application of TenCate Polyfelt® PGM-G (tensile strength 100/100 and 50/50). Reliability, past experiences with this material, and an excellent cost-benefit ratio were the deciding factors in this choice.
TenCate Polyfelt® PGM-G 100/100 is a mechanically bonded polypropylene non-woven with a grid of fibreglass yarns of high tensile strength. Functions include stress relief, sealing and reinforcement. For years, the material has been used in the repair of bitumen road surfaces and installed between asphalt layers or directly on the (concrete) substrate.

Once installed under or between the new bituminous wearing courses of the runways, TenCate Polyfelt® PGM-G retards crack formation and increases the service life of the pavement.
In total the work involved approximately 15,500 m2 of TenCate Polyfelt®
