To be able to deliver the optimum solution to the client, we offer a number of products and processes, designed to fit the maintenance requirements.
The following process can be offered as potential solutions, based on the level of deterioration and maintenance requirements.
Preservation works through a Gilsonite rich membrane that penetrates into the upper surface layer. The membrane permits the binding of the surface aggregate and surface fines, to form a protective sealant, whilst sealing in essential oils and resin. This sealant offers a high barrier of defence against surface oxidation and deterioration as well as stopping water penetration and salt ingression.
Slurry surfacing is a relatively cheap alternative to traditional surfacing options, that allows runways and taxiways to restore pavement surface friction, at a fraction of the cost. Our slurry teams are fully converse with working within the Defence Estates standards and specialise in airfield refurbishment.
Repave Hot In-situ Recycling
Repave is a hot in-situ recycling technique offered by Colas Ltd. The process involves heating up, scarifying and recompacting the surface, while then applying a new thinner layered surface course. The benefits of the repave process are that existing materials are reused, thus reducing both CO2 and Energy consumption , reducing the use of expensive virgin materials and providing a strong thermal bond to reduce any minor cracking.
Both deep in-situ and shallow in-situ recycling can be utilised on taxiways, car parks and general aviation areas to utilise the existing materials to restore the strength and serviceability back to the pavement.
The processes involve reconstituting the material and adding either cement or bitumen to rebind the surface prior to compaction.
To recycle in this manner not only has excellent green credentials but can also be economically advantageous.
This is the removal of up to 50mm of old asphalt, and then the reinstatement of the runway with new asphalt. UKAS approved laboratory teams are available to ensure total quality control. They can advise the best resources needed for your situation. We have our own resurfacing group and equipment available at your disposal.
