KATFIX DSK
KATFIX DSK by POSSEHL is a standard construction method for the maintenance and repair of traffic areas made of asphalt and concrete according to ZTV BEA-StB 09/13, which has been proven and continuously developed since the 1980s.
The microsurfacing asphalt consists of:
- Particularly high-quality and polish-resistant natural hard aggregates of graded grain size up to 8 mm (mixture of coarse and fine aggregates as well as own filler) according to TL Gestein-StB.
- Cationic, polymer-modified bitumen emulsion C65BP6-DSK according to TL BE- StB with bonding agent and additive additives
- Standard cement for crushing time control
- The polymer modification of the bitumen in the cationic bitumen emulsion causes an extension of the plasticity range, i.e. greater flexibility at low temperatures and higher stability at high temperatures. DSK pavements thus become significantly more flexible and resistant to deformation. DSK mixes are produced and laid using special, self-propelled mixing and laying machines. High formulation accuracies are achieved through state-of-the-art computer-controlled metering technology. KATFIX DSK is recommended for the following areas of application:
- Leached (open-pored) asphalts
- Rutting
- Lack of skid resistance
- Inhomogeneous appearance
Safer with KATFIX DSK
Shortened braking distances
Reduced risk of aquaplaning
Less spray plumes
Better visibility in the dark
No danger from subsequent binder accumulation on the surface
Reduced icing of exposed flyover sections in winter
DSK has been shown to reduce CO₂ emissions
Less energy. Fewer emissions.
A recent study by the Institute for Sustainability in Construction at RWTH Aachen University shows that thin asphalt surface courses laid using the cold-laying method (DSK) generate up to 72 per cent fewer CO₂ emissions during the construction process than traditional hot-laying methods.
The study examined, among other things:
- CO₂-Emissionen
- Energy consumption
- Fuel consumption
The lower emissions are primarily due to reduced energy consumption and the avoidance of high mix temperatures.
Key findings of the study
Measurable benefits of cold construction
The study demonstrates clear environmental benefits of DSK compared to traditional hot-mix construction methods:
- up to 72% lower CO₂ emissions
- up to 50% lower energy consumption
- significantly lower fuel consumption
- processing at low temperatures
Why does DSK produce less CO₂?
Lower energy consumption
Compared to traditional hot-mix construction methods, the cold-mix method requires significantly less energy during the construction process. There is no need for high mix temperatures or energy-intensive drying processes.
This allows emissions to be significantly reduced even during the mixing process.
