Joints and seams in
asphalt and concrete
Diverse solutions for rolling trafficThere are multiple causes for damage to asphalt and concrete roads: Roads that are designed improperly, excessive use and damaging environmental influences are a drain on public finances.
The weakest points in roads are joints, seams and connections in asphalt and concrete.
- Joints are spaces between two asphalt or concrete layers, or between their layers or components, such as kerbs, manhole covers etc. These joints are either intentional or necessary for the working situation in question.
- Seams are contact surfaces that are created when asphalt mix is laid in lanes, alongside or near to breaks in the application of the asphalt (longitudinal or lateral seams).
- Connections are contact surfaces between different asphalt mix types (e.g. rolled asphalt & poured asphalt) or around components, e.g. near kerbs, plaster etc.
Perfect joints and seamsFor decades, TOK® bitumen joint tapes have proven themselves as the ideal solution for joints and seams. The tapes possess exceptional stretching and adhesion properties and can be applied cold (self-adhesive) or using a burner. Many TOK® tapes do not require you to go through the time-consuming process of applying a primer, which saves a significant amount of time and money.
Unbeatably fast and preciseOur TOKOMAT® enables fast and reliable finishing of joints on milled and cut edges, particularly on motorways and national A-roads. The machine-extruded bitumen joint tape creates a joint that is appropriate for the profile and height, even on poorly processed surfaces. With an application rate of around 15 m per minute, TOKOMAT® is an exceptionally fast and precise solution.
Secure seamsSeams must be painted over with polymer-modified bitumen or a bitumen-based binding agent. TOK®-Plast is a cold-processed, stable material made from polymer-improved bitumen, making it ideal as a permanent seam treatment. Using the PLASTOMAT®, developed specifically for this product, TOK®-Plast is easy and quick to apply.
Protection of sensitive jointsLIQUITOL®-VT is the ideal solution to protect joints against the ingress of petrol and aircraft fuels, heating oil, diesel, unused oil and inorganic lyes. LIQUITOL®-VT is solvent-free and ETA-certified, for use in storage, filling and transport applications and in manufacture, treatment and usage settings.
