Airfield pavement preservation is a Time Striping specialty and we highly recommend asphalt rejuvenation for airfield pavements. Rejuvenators work by penetrating pavement surfaces and restoring the chemical imbalances found in aging asphalt. This process dramatically reduces viscosity and brittleness while increasing ductility and flexibility.
In addition to its ability to rejuvenate, Lone Star’s WD-2000, Time Striping’s rejuvenator of choice, is a very effective sealer. The capability to penetrate gives WD-2000 unique sealing characteristics. Asphalt surfaces treated with WD-2000 are protected from ultraviolet rays as well as being fuel, water, and chemical resistant.
WD-2000 is durable. During thermal cycles, WD-2000 contracts and expands at the same rate as the asphalt. In comparison, coal-tar emulsions and other seal coats simply lay on the surface. They undergo a markedly differing expansion and contraction rate from the asphalt. This eventually leads to cracking, pin-holing, and delaminating. WD-2000 does not suffer from these problems; through penetration, it becomes an integral part of the asphalt.
The product has been proven by testing performed in the United States by the FAA and independent testing labs for over 40 years. These tests have shown that the product reverses the asphalt age by lowering the viscosity of the oil in the pavement and increases flexibility of pavement. These tests are very important, because for a product to be a true asphalt rejuvenator it has to lower the viscosity not just for the first 30 days, but also for years, and keep the viscosity lowered. Our product does this and more, thereby extending the lifespan of your pavement.
