What is RejuvaShield?
RejuvaShield is the world’s leading asphalt rejuvenator. This revolutionary product, made from coal tar, aromatic oils and specialty solvents, revitalizes, seals and protects asphalt pavings, such as airport runways, roads and highways, commercial roadways and parking lots. It’s scientifically designed to ‘reverse’ the aging process of asphalt pavement extending its life-cycle.
RejuvaShield works 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, making the asphalt less prone to cracking and deterioration.
Unlike old fashioned seal coats, a single application of RejuvaShield penetrates the pavement to rejuvenate and protect the asphalt by replacing the tars and bitumens lost due to oxidation well below the surface. It also seals and protects the pavement against water, sunlight and chemical contaminants, dramatically improving the durability, lifespan and curb appeal of the asphalt.
Proper maintenance is the key to protecting asphalt from the external factors that wear it out. RejuvaShield, applied every three to five years by a certified applicator, has been proven to extend the life of asphalt pavements significantly while reducing life-cycle costs.
Application Method
RejuvaShield’s emulsion-like form makes it easy to apply.
Application rate
RejuvaShield’s optimal application rate is dependent on pavement design, age and existing pavement condition. A test patch should be completed 24 hours prior to application to determine the optimal rate. In general:
In the eastern hemisphere, where application is figured by weight;
Average rate for roadways: approximately 4-5m²/kg
Average rate for aircraft runways: approximately 3m²/kg
In the western hemisphere, where application is figured by volume;
Average rate for all applications: 3.4 sq meters per liter (15 sq yds per gallon)
Machine application
For applications covering a large surface area, RejuvaShield can be applied with a precision spraying machine such as a DESCO D200. This compact machine contains a computer-controlled flow rate to ensure uniform application of the material. As a point of reference, a DESCO D200 can treat an area of approximately 5,000 – 8,000 m² per hour.
Manual application
For smaller areas, RejuvaShield can also be applied manually using simple roller-brushes. A site area of approximately 50 – 75 m² per hour (per person) can be treated using this method.
Conditions for application
RejuvaShield should be applied to pavements before they begin to show the deleterious signs of age. The surface must be clean and dry with a surface temperature of 10°C(50°F) or above. Depending on weather condition and porosity of the asphalt surface, RefuvaSeal usually takes about 4 to 8 hours to dry.
Technical Data
RejuvaShield meets FAA’s P-632 Specification, Engineering Brief No. 44B and TXDOT specification for sealer / rejuvenators.
