Nowadays, China's economy continues to develop, especially in the construction of highways, the original muddy cement road has also become asphalt road, but what people did not expect is that Japan and China treat asphalt roads in diametrically opposite ways.
China's asphalt road "two days for a major repair, three days for a small repair", it can be said that frequent repair, on the other hand, once Japan is completed, even if it is not managed, the road surface is still as good all year round.
This can't help but make people wonder, why is there such a big gap between the same asphalt roads? Is it really because the technology is not as good as people?
Japan Kusei Road
As the saying goes, "If you want to get rich, you must first build roads." ”
Japan is a small country, but it is a hard-working country, and it is especially common to every household, and this problem will gradually be discovered.
Why do you say that? Here's an example.
If Chinese people may clean the room from time to time when managing the room, after all, the Chinese think that the room does not need to be cleaned in large quantities, which is a waste of time.
But this is not the case in the eyes of the Japanese, who clean their rooms every day, and they also clean the floor, and they even take off their shoes when they enter the door.
From here, you can see how clean the Japanese are about hygiene, and in addition to this, they also clean the road in front of the door without leaving any traces.
Nowadays, not only China, but also Japan and other countries around the world are continuing to develop economically, and foreign trade has caused great tension in all aspects, including roads.
There are many types of roads, but the most common type of road is asphalt road, and it is precisely because asphalt road is popular all over the world that Japan has begun to follow in the footsteps of asphalt road.
But the asphalt roads in Japan are different from the asphalt roads in China, and if you go to Japan, you can find that the asphalt roads paved in Japan are very regular, and the roads are narrow, which adds another picture.
The road is dark and neat, and the white line in the middle of the highway or the zebra crossing is clearly visible, and there is no trace of retreat at all.
Another major phenomenon is the problem of hygiene, the asphalt roads in Japan are very clean, and there is hardly a trace of garbage in sight.
This stems from the training of cleaning personnel and highways, and the so-called highway maintenance means that there will be special personnel to clean the asphalt roads every day.
As a result, from a distance, it is pitch black and there is not a speck of dust in sight.
Today, more than 90% of Japan's roads are made of asphalt, and not only in cities but also in the countryside.
It can be said that in Japan you can hardly see concrete roads, they are all asphalt roads.
In fact, Japan was able to achieve this phenomenon more quickly, and this originated from its development.
Japan developed asphalt roads much earlier than China, as early as the end of the 19th century, it has already begun to be implemented, but when the asphalt road development was implemented.
At that time, the roads in Japan were basically dirt roads in the countryside, and there were no ordinary roads, but Japan was a country that could not be idle, and it liked to learn and learn from it.
As a result, Japan quickly turned its attention to roads, and asphalt road technology was also imported from abroad, but after using it for a while, Japan found that the technology of other countries was not suitable.
As a result, Japan began to study asphalt road materials for a long time, and after years of research and development, Japan also began to pave asphalt roads on a large scale.
However, before the asphalt road was developed, World War II broke out, and Japan had to stop the project to be busy with the military.
The asphalt road was badly damaged by the interplay of artillery fire and ammunition, and it was not until the end of the war that Japan began to rebuild the road.
At this time, the United States and Japan cooperated closely, and the United States not only provided military assistance to Japan, but also did the same in economic construction.
At that time, although Japan had mastered asphalt technology, the facilities were not perfect, and there were certain problems with materials, but with the help of the United States, these gradually began to be solved.
In the mid-20th century, there were barely 20,000 kilometers of asphalt roads in Japan, but there were still very few.
It was not until 1975 that the situation was resolved, and it was precisely because of the incomplete materials that the asphalt road suffered some damage one after another.
It is important to know that unlike other countries, Japan is small in that natural disasters such as volcanoes and earthquakes occur frequently, and road surfaces are inevitably damaged.
The reason for the damage is the asphalt material problem, it is precisely because of these in mind, Japan began to formally study the recycling technology of asphalt concrete, once this technology is successfully developed, marking Japan on the road of asphalt development another big upgrade.
According to statistics, up to now, the utilization rate of the removed material used in asphalt in Japan has reached 99%, which shows the degree of control over materials in Japan.
Moreover, the recycling rate of the recycling technology studied in Japan is not low, reaching more than 50%, in fact, the reason why Japan can achieve this degree is mainly because it pays too much attention to the development of asphalt roads.
According to statistics, the total output value of asphalt equipment in Japan is as high as more than 15 billion yuan every year, and the amount of asphalt used is also quite a lot.
So, why are China's asphalt roads repaired so frequently compared to Japan's asphalt roads?
China asphalt road
First of all, in order to understand this problem, we need to understand the construction and development of asphalt roads in China.
Asphalt road construction has only begun to develop since the founding of China, but the domestic economy was not very good at that time, coupled with the need for rapid development of heavy industry.
Although asphalt roads have been developed in China, there are not many of them in general, and most cities and villages are still concrete or dirt roads.
However, since the reform and opening up, China's highways have developed by leaps and bounds, especially asphalt roads, because of frequent foreign trade, China has been using imports and domestic resources to carry out.
At the end of the 20th century, China's asphalt roads have reached more than 1 million kilometers, and in 2013, the domestic asphalt output was 19.9351 million tons, much higher than the previous year.
However, in terms of relative highway construction, China's highways now reach more than 5 million kilometers, and asphalt roads have also been crushed by Japanese asphalt and other highway construction, of course, this is also due to the land area.
But even so, there are still many problems with China's road construction, such as the lack of asphalt materials, which makes China mainly use cement and concrete as raw materials.
Because this kind of concrete is cheap, and has the characteristics of heat resistance and wear resistance, it can be said that it plays a key role in China's rapid development.
There are pros and cons, since the development is fast, there are many problems, because the domestic environment is different in all seasons, the temperature difference is huge, whether it is an asphalt road or a cement road, it will gradually break.
It is the same in both southern and northern China, and although there are long-term natural disasters like Japan, climate change alone has an impact on roads such as asphalt roads.
For example, in summer, when the temperature reaches a maximum of 39 degrees Celsius and is close to 40 degrees, the problem of asphalt pavement may be a little higher at this time, so that both the vehicle and the road surface will be damaged.
Although there are sprinkler trucks and other facilities in this process, which can reduce the temperature of the road surface, it can only slow down, but will not completely eliminate it, and over time, the road surface will also split.
In addition to temperature, cargo unloading is also a problem, and now there are many vehicles in China, every household buys a car, and there are countless trucks.
At this time, it is inevitable that there will be overloading, which will make the road surface under pressure and vibration for a long time.
At the same time, if you want to build a major project such as floors, you will use a large number of machines, which need to build a foundation for further modification of the road surface, and in the process there will be fractures and collapses.
Looking at these factors, China's asphalt road construction is frequent, and it should be, after all, the land area is large, coupled with various factors, it is not surprising.
So, why is there such a big difference between asphalt roads in China and Japan?
Cause situation
First of all, there is the issue of materials, and the materials used in Japan and China are different, and although Japan uses asphalt materials, it has been improved compared to China.
Therefore, the cost is relatively high, and China is short of asphalt, which is not only a matter of cost, but also about the domestic economy.
Therefore, asphalt road and cement concrete, the latter still accounts for a relatively large proportion, after all, both in terms of price and economy, the latter develops faster.
But with the economic development, the economy has also driven the development of asphalt roads, it can be said that China's concept of development is a correct choice.
Since the materials are expensive, they must be very good in terms of materials, and it is precisely this situation that Japanese roads do not need to be repaired frequently, and the equipment that is commonly used in Japan for maintenance is naturally very good.
It is worth mentioning that China will not do this, on the one hand, the area is too large, and on the other hand, the time and cost are relatively high.
As we all know, Japan's land area is a drop in the ocean compared to China's, just as "a bird is more than a phoenix" and "a lake is more than the sea".
However, due to the small size of the country, the asphalt roads paved in Japan are very narrow, and basically the whole country is wide.
As a result, Japan has been able to concentrate on asphalt roads, which are considered to be better because they are narrow.
Finally, there is the issue of social life, Japan is a coastal country, and when it comes to cargo transportation, most of them are ships, and there are few trucks.
In this case, the asphalt road is not under a lot of stress, the damage is not so frequent, and when people travel, unlike in China, the number of people who go to work and drive outside the road is relatively small.
This is due to the small size of the area, and most of the people take the subway or walk. In short, Japan has made asphalt roads play a huge role based on its own geographical advantages, while China has chosen the right development path according to its own national conditions.
Author's point of view
Although the asphalt roads in China and Japan are different, each country has its own advantages and characteristics, and because of this, the domestic economy will be developed, and the same is true for asphalt roads.
If a country cannot learn to innovate and develop R&D, it is difficult for the economy to develop, especially on the road, and the right plan should be developed.
