With the rapid development of infrastructure construction in recent years, the United States has introduced an innovative method - burying a layer of tires in highway construction. The main aim of this initiative is to improve the resilience and durability of roads, thereby extending the service life of roads and improving driving safety. At the same time, the application of this technology in China has not yet been widely carried outEconomyand the environment.
In order to achieve increased durability on highways, the United States has adopted an innovative approach to embedded tires in the road construction process. The method specifically involves cutting waste tires into small pieces and mixing them inBitumen, this mixture is calledRubber asphalt。Studies have shown that:Rubber asphaltNot only can it reduce road noise, but it can also improve anti-skid performance and reduce vehicle wear. In addition,Rubber asphaltRoads are more resistant to freezing in winter, which reduces maintenance costs.
However, this technology is not widely used in road construction in China. One of the reasons is related to the utilization system of China's waste tires. In the United States, the utilization system of waste tires is relatively mature, which can effectively convert these waste tires into road construction resources. In China, the best channel of waste tires has not yet been perfected, and a large number of waste tires have not been effectively utilized, which is limitedRubber asphaltApplication of technology.
Another reason is technology andEconomyFactor. AlthoughRubber asphaltIt has significant advantages, but its preparation and laying costs are relatively high. This in ChinaEconomyIn fast-growing countries with large-scale infrastructure construction, cost is an important consideration. In addition,Rubber asphaltThe production and construction techniques are relatively complex and require specific equipment and technical support, which also limits its promotion in China to a certain extent.
Environmental factors are also not widely adopted in ChinaRubber asphaltOne of the reasons for technology. Although the use of waste tires can be considered a form of recycling, there is a difference in tire cutting and preparationRubber asphaltprocess, may produce certainEnvironmental pollution。In the face of severeEnvironmental protectionAt a time of challenge, China needs to be more cautious in introducing new technologies to ensure that they do not impose additional burdens on the environment.
To sum up, the practice of embedding tires in highway construction in the United States has obvious advantages in improving road performance, however, due to technology,Economyand environmental factors, this method has not been widely used in China. In the future, with the development of technology, the reduction of costs and the rightEnvironmental protectionWith the increased awareness, it is possible that this technology will be more widely used in China. In order to achieve this goal, improving the utilization system of waste tires, increasing technology research and development and policy support will promote this technologyCritical
In conclusion, although the technology of embedding tires in highway construction in the United States has obvious advantages in improving road performance, due to technology,Economyand environmental constraints, this method has not been widely used in China. The future will follow the development of technologyEnvironmental protectionWith the increased awareness, this technology may be promoted in China. We are looking forward to the improvement of the utilization system of waste tires, as well as the rightRubber asphaltFurther attention and support for technology research and development and application, so as to inject new vitality into China's highway construction.
