Why are they all asphalt paved, and China s roads are repaired every year, but Japan is as new every

This is because Japan will conduct surveys after the roads are built, and they will not be put into use directly like China.

There are many people and cars in China, and there are many trucks, logistics, and express delivery in China, and a little carelessness when driving will cause damage to the road surface, so it has caused China's roads to be repaired every year.

Many Japanese companies focus on quality and ingenuity, so they choose the best materials and the most advanced technology when constructing, while in China there are always people who cut corners.

It's all "asphalt" paving, why is Japan as new every year, but China is full of patches?

The main reason is that most of them use petroleum asphalt and imported asphalt, and the road construction is completed in accordance with the asphalt road paving standards. It's not because China's asphalt roads are not as good as Japan's, but because Japan's asphalt roads have a long history of construction.

Since 1878, Japanese officials have been building roads non-stop. At that time, the paving method adopted in Japan would be the same as that of most countries to build asphalt roads, and the roads were not paved in accordance with the relevant standards. As you can imagine, the roads were potholed and not very useful until petroleum asphalt was introduced in Japan.

If you've arrived in Japan and completed the tour, you'll notice that the asphalt roads in Japan are clean and shiny. Actually, this state is related to the materials used to build the road. Some asphalt** is very cheap, but it is difficult to get large-scale use and long-term use.

Since Japan suffered from low-quality asphalt, officials began to use petroleum asphalt. Since then, the level of the road has been continuously improved, and the state of the road has remained as good as new.

There are no rules, especially in the construction industry. Rather than being a vital part of the process, low-quality construction materials can lead to house collapses and roads become potholes. In the process of development, Japan has continuously found that European and American countries use stricter standardized standards for the construction of asphalt roads.

Japan has combined the same standards with the reality of asphalt road trimming in Japan, and a series of industry codes and standards have emerged that apply to asphalt paving roads in Japan. Since then, it has been difficult for low-quality asphalt roads to occur in Japan.

In general, construction materials and construction specifications are indispensable, and although some companies will be opportunistic, this kind of behavior will only lift a stone and hit themselves in the foot. Due to the different regulations and standards for the construction of asphalt roads in each country, not all countries are able to keep asphalt roads clean at all times like Japan.

I think it's largely due to the fact that China has a large population and freight is relatively developed, and there may not be so many trucks on Japan's Liqun Highway, so it looks relatively new.

The main reason is that they usually love cleanliness and take care of these things, so they look relatively new, not that China is not as good as them.

Because China's roads are so long, if they were all renovated, it would require a lot of financial resources, so they had to be patched to reduce the cost.

Because Japan has a strong economy and a small land area, it spends a lot of money every year on road maintenance. However, China's territory is vast and its economy is developing rapidly, so it is mainly repaired.

I think it is China's large land and abundant resources that make it expensive, so it can only be partially repaired. In Japan, the area is relatively small, so I have the energy and financial resources to build a new one every time.

In 221 B.C., Qin Yingzheng unified China, and he later issued a traffic decree of "cars on the same track". The so-called "car on the same track" is to require all localities to keep the road unimpeded. It can be seen that the rulers of more than 2,000 years ago attached great importance to the construction of transportation roads.

Objectively speaking, the construction of road facilities is very important, not only conducive to the travel of the people, but also has a very deep impact on the construction of the country, the transportation of transportation, the development of commerce and trade, and even the deployment of military and resources. However, Zhuge Liang and Jiang Wei's 16 Northern Expeditions were always unsuccessful, and there was a big reason: the roads were not conducive to the soldiers' expeditions, and the grain was inconvenient to transport.

This shows that the smooth flow of roads is very important to the country. If we dig at the history of China, we can often find such an unwritten law: basically the ancient disputes between the north and the south ended in the victory of the north; In other words, the battle for unification is usually fought from north to south.

In 1399, Zhu Di, the king of Yan, launched the Battle of Jingnan with only one place in Beiping, and later attacked from north to south, won the war in only 3 years, and finally sat on the dragon chair. It turned out that in ancient times, there were many plains in the north, so the roads were smooth, and there were many prolific horses, so they often occupied the advantage of "advancing and retreating freely" in wars.

On the other hand, there are many rivers or mountains in the south, and they lose the protection of the mountain and water barrier when they fight the northerners in the plains, so they are naturally not opponents. Since roads are very important to the construction of the country, there are obvious differences between China and Japan today in this regard.

They all use asphalt to build roads, but China's roads are always like they have just been built; But everyone else looks like new in Japan. What is the reason for this? The Japanese take their work very seriously, and their rigorous attitude has led Japan to adhere to the principle of "quality first".

For example, they don't sacrifice quality to catch up with the schedule, and they take all aspects into account when building roads, and often the road construction in China is completed before others start construction. In addition, roads in Japan are operated while they are being constructed, and if they are driven correctly, construction will continue, and if they do not, they will be rectified. So their asphalt roads always look like new.

However, China's path will often change due to economic factors, and even the phenomenon of "one day at a time" will appear. Coupled with the fact that China's roads are often built first and then related facilities, such as water pipes or subway lines, and other new facilities, our roads seem to be being built all the time.

Because China is a populous country and has many vehicles, especially in the rapid development of infrastructure, many large trucks will pull muck or heavy goods on the road, which will cause varying degrees of damage to asphalt roads over time, while Japan's demand for infrastructure is not so frequent, so there are fewer such large trucks and less wear and tear on the road.

The same asphalt paving, China's frequent repair, and Japan is indeed new every year, this is because China's road maintenance standards are not standardized, many quality is uneven, and there is no unified standard for materials, so it is often repaired.

In the case of dense Chinese population, large project construction volume and little time, the quality of the project cannot be guaranteed; In Japan, the construction of roads is long, and the quality of the project is guaranteed.

Economic development means building a lot of infrastructure, and the increasing number of important projects also means that there are a lot of related social problems, such as environmental problems, maintenance problems, transportation problems, and so on. As the saying goes, if you want to get rich, build roads first. The speed of our road construction is obvious to all, and roads of various materials are being built, but in the case of rapid economic development, many problems have also arisen.

When it comes to roads, the most common thing we see is asphalt roads. Asphalt is inexpensive, cohesive and cost-effective, so asphalt is always preferred as a raw material when building roads. The asphalt has a black surface and becomes very viscous when heated at high temperatures, so it is paved on the road before the temperature drops, and then pressed by a heavy press, and when the temperature drops and dries, it will be tightly bonded and become a solid road foundation.

The same asphalt road has a wide use value in Japan, and asphalt is often used as a raw material to build roads in Japan.

But we are all prone to notice a problem, our asphalt road is always easy to lead to the city's appearance, because it is always too late to wait for the road to dry, the vehicle will drive over, leaving a black mark to fly away. Not only that, but it's also asphalt roads, so why do we have to repair them so often? It's always a pothole here, a mess there, and it looks untidy.

And Japan's is as smooth as new?

If you want to explore the answer to this question, you can consider the following aspects. The first is the design process, because the road is built in the open air, and the materials will have a certain thermal expansion and contraction with the temperature. Therefore, at the beginning of the design, it is necessary to take into account the local temperature and the depth of the material curvature, flexibly adjust and use the thickness of the asphalt, and appropriately increase or reduce the moisture, but the asphalt roads in our country are generally one-size-fits-all, and the specific analysis of specific problems is not carried out, and the construction is carried out without in-depth investigation of the local environment, so it will lead to certain hidden dangers at the beginning of the construction of the road.

The second is the issue of road maintenance. Our traffic flow is very dense, including heavy vehicles, and many asphalt roads generally have a certain load capacity, long-term pressure over the load capacity will lead to the deformation of the road, not only that, in the emphasis on speed is productivity today, asphalt roads are often not completely dry, not to meet the use of standards, has been put into use. This directly leads to the uneven settlement of the asphalt road, and various accidents such as fracture will occur in the future, which directly affects the service life of the asphalt road.

The maintenance of the asphalt road is not timely, under normal circumstances, the only time in the life of the asphalt road is only two opportunities to be repaired by workers, one is just beginning to build, one is the last eradication, which will greatly waste social resources, manpower and material resources, will also affect the smooth flow of the road.

Because the foundation of each country is different, there are no resources that can be mined under the roads in Japan, so it is just ordinary roads, and many natural resources can be mined under the roads in our country.

This can only show that we use it more frequently, and our country is in the development stage, and the technology may not be as developed as others.

It is for the spirit of Japanese craftsmen, who value moral quality and exert their craftsmanship spirit. This spirit is something we admire.
