tl-2000 asphalt maintenance road coating
TL-2000 is a black liquid single-component polymer composition for asphalt maintenance to be applied to the surface of asphalt concrete road in a thin layer by pouring or spraying and subsequent spreading. A thin-film coating is thus created. The hardening time is 60 to 90 minutes (depending on the ambient temperature), i.e., in 60 to 90 minutes the road may be reopened for traffic. The method being proposed is compared with the existing ones in the table below.
TL consumption is 0.7 to 1.2 kg/m² depending on the road pavement condition. Adhesion of the sealcoater to the road surface primarily occurs through chemical combination with the bitumen component.
The active gaseous component of TL2000 penetrates into the bulk of asphalt concrete to a depth of 40-60 mm and chemically combines with the bitumen forming a copolymer bitumen composition having the necessary elastic properties. Except for asphalt maintenance & road coating, TL performs the following main functions: After its applied as road coating and has completed hardening (complete polymerization), we obtain a thin membrane coating preventing penetration of water and gases including ozone into the road pavement and protect the road from ultraviolet and infrared solar radiation and various chemicals.
TL-2000 does not contain solvents and does not cause any damage to the road. This asphalt rejuvenator also allows an increase in the road grip of a rubber tyre by about 20 to 30% and thereby considerably shortens the braking distance and improves the traffic safety. Since TL-2000 is practically impervious to water, this considerably (by 40 to 50%) decreases the consumption of salt applied to the road surface in winter. TL-2000 can be used not for road coating and asphalt maintenance only! The available modifications of TL allow other applications as well:
All modifications based on TL-2000 are liquid single-component compositions hardening in contact with air. They will not freeze at temperatures of about -30°C.
In sealed barrels or other containers, the material can be stored even in the open air for up to 2 years. Thus, a highly effective asphalt maintenance rejuvenator is avilable.
Its main features are as follows:
1. Application of the coating material to asphalt concrete pavements of motor roads, airfields, storehouse floors, etc. ensures a considerable increase in service life of the road pavements and imparts them impermeability and resistance to water, acids, alkalis, oils, gasoline, and salt solutions.
2. It is possible to obtain colored asphalt concrete surfaces.
3. It is possible to utilize ash and various other pulverous materials.
4. Application is easy, quick, cheap and convenient.
5. All the materials used for equipment cleaning (kerosene, diesel fuel, etc.) as well as the equipment itself are not expensive or difficult-to-obtain.
6. Application does not require special facilities. If the volume of work is rather small, brushes or rubber spreaders can be used.
