Asphalt Recycling

Asphalt Recycling UK Limited is a company that provides local councils and maintenance term contractors etc, with a solution to recycling their waste asphalt into premium hot mix asphalt.

We hire or lease mobile & static Asphalt Recyclers providing a service alongside sales and advice on our range of additives & rejuvenators. We also undertake surfacing work and associated civils.

• Financial Savings
• CO2 reduction
• 100% Asphalt Recycling
• A fully sustainable solution

Surfacing
Asphalt Recycling offers up to date technical advice to architects and surveyors on specifications for Tarmac surfaces eg. Industrial and HGV.

We can undertake surfacing work, Hand lay and Machine lay, and associated civils for:

• Roads
• Footpaths
• Driveways
• Playgrounds
• Car parks

Covering Wiltshire, Gloucestershire, Berkshire, Oxfordshire and Avon. Also London and the Home counties. Approx. 90 mile radius of Swindon.

Environment
As the volume of waste and by-product materials are generated in our society and the cost of disposal continues to increase, there is increased pressure to recover and recycle materials. Non renewable natural resources such as aggregate and bitumen are preserved when recycled 100% into a high value premium hot mix asphalt. Generally waste asphalt is either crushed and reused as a low value secondary aggregate into a sub base, which results in a loss of non renewable bitumen coated aggregate, or its usually land filled.

On-going research and development..
Over the past five years we have been undergoing separate research and development for the remediation of hazardous Coal Tar waste

Rejuvenators & Additives

Additive: VOC emission suppressant (Volatile Organic Compounds)
During its original lifecycle Asphalt may have come into contact with rubber, oils, resins, road markings etc. When the reheating of waste asphalt takes place emissions from the organic & inorganic compounds are released sometimes creating an acrid odour. Independent Test Results demonstrated that no volatile components were detected in the treated sample, whilst in the untreated sample increasing higher molecular weight hydrocarbons were found as volatile components.

The suppressant had reduced the volatile emission to a level below the detection limit of the instrument. The product is effective against both organic and inorganic odours. It is non toxic, non hazardous & biodegradable. It contains no harmful VOCs and is safe for both humans and the environment.

Rejuvenators
Most of the binder about 4-7% is still contained in the original material. By adding approx 1-2 litres of rejuvenating oil or 1kg of rejuvenating wax (depending on proven binder content) to 1 tonne of old or contaminated asphalt will replace oils that have dissipated or oxidised from its original form reversing the aging effect.

• Rejuvenating Oil is suitable for footpaths & cycle ways etc.
• Rejuvenating Wax has a stronger effect than the oil and can be used when carrying out minor highway repairs etc.

Rejuvenators provide longer term beneficial effects on bitumen, also a measurable effect on the binder properties, producing a more workable material. The recovered penetration and softening point test show significant differences for these materials both increased the penetration and reduced the softening point of bitumen. Before and after tests were independently carried out in UKAS accredited laboratories by ESG Scientifics complete with data reports. Rejuvenators have a higher melting point than conventional bitumen benefitting the customer in an era of increasing warmer climates, also more resistant than conventional bitumen’s during colder temperatures.

Coal Tar Bound Material
Coal tar was widely used up until the mid 1970’s and is most likely to be found in the underlying base in highways or sometimes found in some surface dressings until mid 1980’s and fuel resistant surfacing. All materials would need to be tested prior to recycling to ensure no presence of coal tar, polycyclic aromatic hydrocarbons (PAHs) – ‘not to be reheated’. A simple on site method can detect if coal tar is less than 150ppm, and or laboratory test to confirm measurement.
