The picture shows the Chinese highway under construction
As the saying goes, to get rich first to build roads, roads are built, people also find the way to become rich, but the road is not built and finished, it will also be damaged with a long period of use, and then it must be repaired, and how do Americans build roads? When they are building roads, what is the use of burying tires under the road? Asphalt highway repair usually has three methods, usually, the use of hot material repair effect is the best, but the most laborious, since this repair method is the most laborious, then why does not China follow their road construction technology? After reading the way Chinese road construction, people understand the wisdom of the East in road construction.

Coupled with the quality of high-grade highways, with the development of the city is becoming more and more important, then the subsequent maintenance and maintenance of the highway has become the biggest problem that people need to face, in a sense how to ensure that a road can be effectively repaired, even more important than building a new road, the United States road maintenance personnel in the maintenance of the road, often buried the abandoned old tires into the ground, with the help of the waste tire structure on the roadbed sand and gravel binding, so as to effectively alleviate the occurrence of the settlement effect under the road surface , which has led to a significant increase in the service life of U.S. highways after undergoing abandoned tire repairs, for which the United States has also filed a patent specifically for this technology that uses tires to repair roads.

Because the material used in the United States to repair the road is waste tires, these tires used on the road will not actually provide additional cost load for the construction of the road, but will improve the stability and load bearing capacity of the road structure because of the constraint ability of the tire rubber, and with the constraint of the waste tire, the gravel as the roadbed cannot slide and settle as freely as in the past, which also makes the service life of the American road greatly extended.
The same tire application method, Chinese is actually being used, but China uses not only discarded tires, but all the waste including volcanic ash, tailings and tunnel waste residue is used to ensure the maximum efficiency of existing waste utilization: just like waste tires, this kind of thing, as early as the 1980s, China has been using, by processing waste tires into rubber particles, and then adding modified agents to mix with asphalt. China has received a special modified rubber asphalt mixture that not only provides durable pavement, but also has its own high viscosity and elastic properties, allowing the road to be within the normal range of use, even if it is placed for 10 years without maintenance.

These two ways of use, compared to the past after the use of abandoned car tires to burn, the benefits of recycling and reusing the combustion debris are much more, first of all, this use of tires and its processing of finished products to pave the way does not produce a variety of toxic and harmful gases, secondly, compared to the high temperature treatment, there is a large number of carcinogens of toxic waste rubber, the use of waste tires to pave the road the processing steps performed by the processor is not dangerous, finally, as long as the paved road is still in use, Their demand for waste tire materials is bound to exist, and they can continue to create value for human beings, which is the biggest feature that simply incinerates waste tires.
So, Chinese is not that they have not reused waste materials like the Americans, but that the East is more accustomed to solving the problem invisibly: the Americans think that using waste tires to pave the way is a good idea, but in China, this paving practice has been Chinese modified to the point where it should be unchangeable.
