Passengers are trying to produce more solid surfaces than recycled plastics


Total plastic made from the 20th century. In the 1960s, 10% was not processed. Most of the time, plastics only spread and fall into landfills. Some of the plastic garbage is thrown out of the wild, rivers and a place where they can reach the sea. As it gets better, the problem of plastic waste will be even more severe. For example, this year should be about 380 million. Therefore, tons of plastics were used for the development of world roads with an annual production of 120 million tons, three times more than bitumen. ton.

These materials have similarities. Plastics are made of petroleum products and bitumen is a by-product of oil refining. They are both polymeric – consisting of long molecules with a strong link. This ensures the durability of the plastic, contributes to its durability. These features are also good for road users. When laying a road, the hot bitumen strengthens the aggregate from crushed rocks and stones and often forms a coating called asphalt. All of this encouraged people to think: Why don't you replace a polymer with the other?

Products made of recycled plastic, such as gutters and sewer pipes. Now he's interested in using it on the road. On September 11, a 30-meter bicycle path was opened by bike in the Zwolle region of the Netherlands on a 70-meter bike path. Recycled plastic and the rest are polypropylene. In this section, a new product, PlasticRoad, is being developed and is being developed by two Dutch companies, KWS and plastic pipe manufacturer Wavin, two Dutch companies, together with the French oil and gas company Total.

PlasticRoad is a prefabricated product. The delivered factory parts are laid on appropriately prepared substrates such as sand. The segments can be placed in hollow, drainage systems, gas pipelines or power lines. For the Zvol yapıl project, the sections were 2.4 meters long and 3 meters wide. Drainage systems are equipped with sensors to measure temperature, bending and water output. Nearby, Githorne, another experimental bike path is in progress.

Not only durable but also smart

If the idea fails, the inventors expect it to develop and produce only segments made of recycled plastic. There will be a series of walking paths, parking space, railway platform. Finally, segments and roads are planned to be produced. They can be equipped with sensors for traffic monitoring. In the long term, contours in plastic paths can be used to support electrical autonomous transport by electrical means.

According to companies, prefabricated plastic roads should serve 2-3 times longer than normal. The price would be reduced, mainly because the roads could be built almost three times faster. A slippery coating, such as rubble, which is traditionally used for road construction, may be included. In addition, modified old partitions can be recycled. However, engineers will see how the wear can withstand wear and the hole creates a resonance that will cause this road to cause too much noise.

Recycled plastics can also be used in other ways – mixed with hot bitumen for asphalt production. Soon, such a sidewalk will be placed on a campus in San Diego in California to test specially designed plastic roadside coatings developed by a British company, MacRebur. According to Toby McCartney, 2015, the company, which has established this company with a group of colleagues, is made of plastic, which is difficult to repair, which brings all the blends to the warehouse.

MacRebur plaster is cleaned, peeled, and turned into sawdust or granules. When laying or repairing roads, these jobs are planned to be done on site, so that local roads can be made from local waste. Each mixture may contain about 20 different polymers adapted to specific surfaces. A blend of a bus lane, that is, y. For the heavier transport, the other provides more flexibility in the arc, and the lateral forces may be missing from the tensioned surface due to the wheels, for example in a transport ring. The coating may also be applied to too much heat or cold. As the plastic is filled with small holes into the surface of the water, the pavement is damaged and the modification of the asphalt can reduce the pit.

The company's plastic blends are already being used for road, parking and airport runway coatings in various countries. The oldest project is probably the road in Cumbria, northwest of England, where trucks often travel. There was a need for new coverage for about six months, but according to T. McCartney, his condition was perfect after two years after mixing in plastic. After replacing the cap, the old one can be recycled again.

Cleaning and separating plastics made from different polymers can be quite expensive, especially for low-value products such as packaging. However, T. McCartney says that the changing cost of bitumen is cost-effective, for example, because bitumen in the UK may cost around 400 liras. And for standard road pavement, the contribution made from recycled plastic adds 300-350 pounds per tonne. The addition of an additive does not require the appropriate amount of bitumen to save money. Now the add-ons are changed by 5-10% bitumen, but some of them can be increased up to 25%.

T. McCartney has developed special accessories for recycled plastic to see how pits are sometimes handled in India. The collected plastic waste is poured into a pit, dipped into the diesel and burned to form a solid mass. It is a rough option that pollutes the environment, but somehow helps you solve the problem. Sometimes in India, crushed plastic is mixed with bitumen and road construction.

Australian travelers also start using recycled plastics. In Melbourne's Creevalne suburbs this year, the 300-mile section of Rayfield Prospect was completed with the material "Veneer". Processed more than 200 thousand produced. plastic bags and packages, crushed 63 thousand. Glass bottles and 4,5 thousand used paints. printer cartridges. After mixing all the components, 50 tons of recycled asphalt were produced and a total of 250 tons of asphalt was produced. The characteristics of this road will be evaluated.

Downer's Stuart Billing, who received the floor, said that the cost of making recycled materials is the same as the traditional ones. However, the road is expected to be used for a longer period and to be more resistant to heavy traffic.

Craigiebernay officials estimate that the amount of waste not stored in the storage area will be spent in the same way that Rayfield Prospect has been built for the last ten years in garbage containers. Local assemblies are more likely to receive complaints about road conditions, especially in pits. The households would probably be lined up for more plastics and recycled, knowing they could travel in Australia and elsewhere, even on smoother roads.
