Dencryl Bridge Traffic

(6-10 mm)

Exposed waterproofing membrane layer as wearing layer.
For bridges where asphalt is not an option, we offer a heavy duty driving wear layer based on a flexible PMMA mixed with hard and extremely durable bauxite aggregate. This system bonds with the substrate and provides a sealed wear layer in combination with a flexible, crack-bridging barrier membrane and surface friction suited for walking and cycling. Dencryl Bridge Traffic provides a low density option to provide a wear, impact and abrasion resistant surface that will offer corrosion resistance, slip resistance and limited maintenance requirements. It can be used on new bridge construction, routine maintenance or bridge restoration applications. Dencryl Bridge systems are only installed by authorised and approved applicators.

Benefits

Will adhere well to dry and clean surfaces including steel and pipe outlets etc.
Will resist rain and snow within 45–60 minutes of installation
Flexibility sufficient to bridge cracks in excess of 3.5 mm in well below freezing conditions.
Very easily repaired if damaged.
Rapid setting and curing enables limited ‘possession’ and rapid handover irrespective of ambient conditions.

Applications

Bridges are continuously exposed to severe stresses and typical factors affecting their longevity, include inadequate protection specified at design phase, quality and handling of concrete and/or steel, physical and chemical exposure, climatic conditions, traffic types and frequency and regularity and quality of maintenance. Dencryl Bridge Deck Waterproofing systems provide 100% effective seamless waterproofing thereby denying entry of water, chloride and de-icing salts from permeating into and percolating through the structural concrete deck and thus preventing the steel reinforcement corroding. This also includes corrosion inhibition of orthotropic steel decks etc. where these are the decks of choice.

Scope of use

Road bridges

Application conditions

Temperature -30ºC to 30ºC, best 15 to 25ºC, max. moisture content in the concrete subfloor 5% by weight.

Appearance

Dencryl Bridge Traffic is a rough singlecoloured bridge covering system. The slip resistance might be varied from moderate to pronounced.

Temperature Resistance

Dencryl Bridge Traffic is resistant to temperature cycles up to 80°C. Extended periods at these temperatures and above will make material susceptible to chemical attack and abrasion wear.

Life Expectancy

more than 30 years
