Specialist Surfacing
Delivering Sustainable Highway Solutions
Colas Surface Treatments include In-Situ and Ex-Situ Road Recycling, Micro-Surfacing, Fibredec Surface Dressing and Slurry Seal. These cold applied treatments reduce emissions, waste and disruption, and can solve the issue of tar contamination. We assist clients in significantly lowering highway maintenance costs and improving the carbon footprint.
We draw upon the experience and expertise of our 1200-strong research and development team to continually improve highway maintenance techniques and treatments that are extremely robust and reliable.
We are committed to reducing direct greenhouse gas emissions by 30% and upstream indirect emissions by 30% by 2030.
Surface Treatment Options
Fibredec
Microsurfacing
Recycling
Fibredec
Fibredec combines bitumen emulsion, chopped glass fibre and aggregate to create a strong, flexible and waterproof design. Applied either as a highly resilient surface material or as a stress-absorbing membrane interlayer (SAMI), Fibredec is highly versatile and delivers significant performance improvements on more traditional surfaces.
Micro-Surfacing
Our Micro-surfacing process is cold-applied so uses less energy and reduces carbon emissions. It comes with a choice of versatile materials so it can tackle a broad range of engineering challenges. Bitutex FP, Paveseal, Ralumac HT high texture, Ralumac and Colmat each offers specific application and performance benefits, and all conform to National Sector Scheme 13 and ISO 9001.
Road Recycling
Heavily deformed, potholed or deteriorated carriageways and footways are broken down and re-used in-situ which minimises disruption, waste and reduces the cost associated with conventional resurfacing. Colas provides a choice of carbon-friendly Road Recycling processes which include Retread and Deep In-Situ Recycling.
Other benefits include:
- Minimal or zero waste is sent to landfill
- In-situ recycling of existing materials with minimal use of imported virgin aggregates results in fewer lorry movements and lower CO2 emissions
- Shorter construction periods minimise disruption
- Tar-bound material is encapsulated and does not need to be exported and processed outside the county
Global Expertise in Sustainable Transport Solutions
Recycol
The new Colas process for quick, economical and clean projects with 100% recycling.
Suitable for most road types, Colas’ new process recycles 100% of the existing surface in-situ and provides a machine-laid finish which can be trafficked almost immediately.
Valorcol
Valorcol is a cold mix surfacing process consisting of reclaimed asphalt pavement (RAP) that is usually 100% of the content.
The process reuses the milled materials obtained from the same site or from existing stockpiles at other construction sites. The reduction in new resources and reduced traffic movements delivers an efficient and effective reduction in environmental impact.
