Why should Americans bury a layer of tires when they build roads? Why doesn't our country emulate this way of building roads?
Convenient transportation is one of the important factors to enhance economic development, almost all cities are carrying out large or small road construction projects, and the United States has opened up a way of tire road construction, so many people have said, really did not think that tires can still have this function, so what is the use of this layer of tires? Do we need to learn from it?
Any long-term use of the highway, can not avoid damage, depression and other situations, if not timely maintenance, will affect the driving safety of passing vehicles, then how to improve the service life of the road, has become a very important research direction, and tires can play this role.
We all know that the United States is known as the country on wheels, with an average of about 80 cars per 100 people, ranking first in the world in terms of car penetration, but the car is a consumable after all, according to the survey, the United States can produce about 300 million waste tires a year, if there is no proper treatment, these tires will obviously pose a threat to the natural environment.
For example, in the 70s of the last century, the united States automotive industry developed very rapidly, but the lack of technology led to the accumulation of tires, when some people proposed to throw tires to the seabed treatment plan, on the one hand to provide a better habitat for corals, on the other hand, also to treat the tires, but the good times are not long.
Osborne Tire Reef has a total of 2 million tires, which has caused great pollution to the surrounding sea, and now it is not only necessary to clean up the tires thrown away that year, but also to spend money to restore the marine environment, which can be said to be self-inflicted! At this time, the problem appeared, abandoned tires can not be littered, the number is still increasing, many scientific research teams have invested in the project of waste tire reuse, and the emergence of tire road repair is the research results of one of the teams.
First of all, the construction team will cut off the sides of the tire, and then dig out the damaged road surface, place the tire tightly on the roadbed, fill and compact with gravel and other materials, and then lay a layer of asphalt, the damaged road surface is intact as before, after testing, this tire paving method can make the filling under the road surface more compact, can better disperse the pressure generated by the vehicle driving, stronger than the pressure resistance of the traditional road surface, not only the use of discarded tires, but also improve the quality of the project, save the cost of road construction, can be described as a one-stroke.
In addition to road repairs, tire filling can also be used when paving roads, and the project has also been successfully patented as a new road construction technology. Seeing that this friend is curious, can turn waste into treasure paving means, the overall strength is still high, why does not our country follow suit?
China's car ownership more and more, the number of abandoned tires is also growing day by day, the relevant scientific researchers have long been aware of the problem of waste tire reuse, the difference is that China's infrastructure projects to face the geological conditions are more complex, with waste tires to build roads the program is difficult to meet the requirements and standards of the project, it is worth mentioning that although tire repair is not feasible, but China's engineers have developed another way to turn waste into treasure.
For example, the use of high temperature to vulcanize the waste tire, and then add steel wire and rubber and other components, so that it can be used again, or the waste tire is processed into rubber powder, and then add a professional mixture combined with matrix asphalt, this improved asphalt cement material has stronger bearing capacity, although it is not directly paved with waste tires, but from the perspective of engineering quality, it can also bring good results, what do you think about this?
