Walking roads try to produce more robust surfaces of recycled plastics



Total 20th century plastic. In the 1960s, 10% were not processed. Most often, plastics only emit and fall into landfills. Part of the plastic rubbish is thrown into the wild, from where it can reach the rivers, and from them – to the sea. As we improve, a plastic waste problem will be even more serious. For example, this year there should be around 380 million. Tons of plastic, therefore, three times higher than bitumen, which is mainly used for world-wide development – producing 120 million annually. tons.

These materials have similarities. Plastic is made of petroleum products, and bitumen is by oil purification by-products. Both of them are polymeric – they contain long molecules that have a strong connection. This ensures the strength of the plastic, which contributes to its resilience. Features of this type are also good for road users too. When placing a road, hot bitumen reinforces the total rock and stone and creates coating, commonly referred to as asphalt. All of this motivated people to think: why not replace one polymer with another?

Products made of recycled plastics, such as huts and sewer pipes. He is now interested in using it on the road. On September 11th, a 30 meter cycle route was opened in Zwolle, the Netherlands, with a 70 per cent cycle route. Plastic has to recycle, and what's left is polypropylene. In this section, a new product, PlasticRoad, is being developed, which together with a Total French gas and oil company is being developed by two Dutch companies – the KWS road construction company and Wavin's plastic pipe producer.

Plastic is a ready product. Segments that are made as a factory are placed on substrates prepared as sand. Segments are made empty, can be introduced to drainage systems, gas pipelines or power lines. Sections of 2.4 meters long and 3 meters wide were made for the Zvolė project. They have sensors for measuring temperature, bending, and water output in drainage systems. Nearby, Githorne, another pilot cycle route is underway.

Not only durable, but also smart

If the idea fails, the inventors expect it to be developed and produce segments made solely of recycled plastics. There will be a row of hiking trails, parking lots, rail platforms. Finally, it is proposed to produce segments and roads. They can have sensors for traffic monitoring. Ultimately, contours on plastic roads could be used to support automatic, wirelessly powered and wireless transport.

According to companies, ready plastic roads should introduce 2-3 times longer than usual. Price would also decrease, mainly due to the fact that the roads could be built almost three times faster. Slippery cover, including rubble, can be used traditionally for road construction. In addition, old segments can be recycled. But engineers will monitor how the path will be resistant to wearing, as well as if the hole creates a resonance that would cause this way to cause too much noise.

Recycled plastics can also be used in other ways – to mix with hot bitumen for asphalt production. Soon, such a pavement located in Cardiff, San Diego, will be a campus to test a number of specially designed plastic plastic covers developed by the British MacRebur company. According to Toby McCartney, 2015 The company, who has set up this company with a group of colleagues, is made from difficult to recover plastic, which often reaches the landfill site.

MacRebur's plaster is cleaned, scratched and chopped into nails or particles. When installing or repairing roads, it is proposed that this work is carried out on site, so that local roads can be built from local waste. Each mix can contain about 20 different polymers, adapted to specific surfaces. One mix can fit on a bus lane, e.g. y For the heavier transport, the other would provide greater flexibility in the arc and due to late forces wheels, the surface of the voltage may be missing, for example in a transportation cycle. Coating can also be applied to much heat or cold. And since the plastic is filled with small holes the water enters into the surface, the pavement is damaged, the asphalt modification can reduce pool.

The company's plastic mixes are already being used for road rail covers, car parks and airports in different countries. The most likely project is the road in Cwmbria, the north west of England, where trucks often travel. He needed a new cover for about six months, but, according to T. McCartney, his condition was excellent after mixing in plastic two years later. After the refreshment of the cover, the old one can be recycled again.

Cleaning and sorting plastics of different polymers can be quite expensive, especially for low-value products, such as packaging. But T. McCartney says that bitumen change is cost-effective, because, for example, the UK's tons can cost around 400 pounds. And for the standard road pavement, the additive made of recycled plastic adds 300-350 pounds per tonne. Adding a supplent would not require an appropriate amount of bitumen, which could save you money. Now 5-10% are replaced by bitumen additives, but some can increase by up to 25%.

T. McCartney has included specialist accessories for recycled plastic, seeing how ponds are sometimes treated in India. The collected plastic waste is poured into a pool, broken into a diesel and burned to form a solid mass. It's an unfortunate and corrupt option for the environment, but in a way that helps solve the problem. From time to time in India, plastics have broken to mix to pomeon and build roads.

Australian travelers are also beginning to use recycled plastics. In the suburban numbers of Melbourne in Creighborne this year, a 300 mile section of Rayfield Prospect has completed the "Plated" material. It produced over 200 thousand processes. plastic bags and packs, grinding 63,000. Glass bottle and paint used of 4,5 thousand. printer cartridge After mixing all components, 50 tonnes of recycled asphalt were produced and a total of 250 tonnes of pavement were produced. The features of this road will be assessed.

Stuart Billing, from Downer, who took the floor, said the cost of building recycled materials was the same as traditional ones. However, it is expected that the road will be used longer and more resistant to intense traffic.

Craigiebernay officials estimate that the amount of waste that had not been deposited in landfill had been spent on the way in which Rayfield Prospect was included in garbage containers for the last ten years. Local councils are most likely to receive complaints about conditions, especially in ponds. And in Australia and elsewhere, households may have been solved and recycled for more plastic if they knew they would be able to travel on even smoother roads.
