Recycling

NMS pioneered the use of recycled planings into asphalt plants in the late 90s. Peter Botterill still holds the Patent for bitumen sand. Unfortunately, the technology at the asphalt plants was not advanced enough for the product at that time and resulted in that part of the business being sold to Hanson.
In 1998 when the first loads of bitumen sand were delivered the expectation was to use 5 to 10 % in new surfacing. With modern methods of asphalt production and quality control of the RAP (recycled asphalt pavement), that aspiration has risen to over 50%.

We are now supplying crushed and graded planings (RAP) to 3 of the major players in the asphalt industry. NMS have with the co-operation and help of Balfour Beatty created a WRAP ((Waste & Resources Action Programme) Quality Protocol. This enables us to deal with waste at source. Once the waste surfacing/road has been loaded onto our disposal wagons the waste is already a product. This product can then be transported direct to the final customer. Environment Agency T5 exemptions for sites are obtained and as a consequence, we do not operate under waste transfer regulations resulting in a substantial reduction in our Clients carbon footprint. The concept of the linear quarry is now a realistic proposition.

Since 2013 most of the product we produce with our modern fleet of Wirtgen planers is transferred to our production centre close to Junction 24 of the M6. We select only the bitumen rich upper layers of the carriageway and transport to the production site for further enhancement into RAP. These bitumen rich products come primarily from Motorway and A roads within the Area 10 motorway network. The Specification for these roads has remained known for the past 40 years and as such we can predict the bitumen content of the resulting product with a large degree of accuracy. Work on the network is carried out almost exclusively overnight and our production site is ideally placed to accommodate the work.

Very occasionally we encounter Tar during our planing operations. Our operatives are trained to sniff out the problem and to confirm it with a PAK spray. Tar can become a major issue particularly if we are not aware of the problem before we get to the site. We now have obtained an S2 exemption to store up to 500 tonnes of Tar bound planings in a dedicated area at our Junction 24 facility. This gives ourselves and our clients the option to ensure that progress on the resurfacing site is not compromised. We will of course be operating under waste transfer and waste management regulations once Tar is encountered. A hazardous waste consignment note will accompany each load of road planings containing coal tar (assuming that the coal tar content is >0.1%).
