However, due to various reasons, although the raw materials and methods used in paving roads in different countries are similar, the situation is not the same. For example, roads paved with asphalt in China and Japan, the roads in Japan look like they have just been renovated, but the roads in China are often potholed and need to be maintained from time to time. Why?
All previous dynasties attached great importance to road construction.
During the Spring and Autumn Period and the Warring States Period, due to the needs of economic development and war, various vassal states were actively building roads. At that time, the smoothness of roads determined the speed of information dissemination, which played an important role in various vassal States, and sometimes even decided the survival of a country.
Since the Qin Dynasty unified its territory, China's road construction has entered a new period. By the Western Han Dynasty, China had initially formed a road network with the city as the center and extending in all directions.
According to relevant data, there were more than 2,000 kilometers of roads in China during the Qing Dynasty. Even during the turbulent Republic of China, road construction in China did not stagnate, but developed rapidly. By the end of War of Resistance against Japanese Aggression, there are 6.5438+0.3 million kilometers of highways in China alone.
There are many highways in China, with rapid development and great road loss.
After nearly a hundred years of suffering, the land of China was devastated, especially when the Kuomintang defeated Taiwan Province Province, taking away what it could take and transferring what it could, such as the treasures of the Forbidden City, such as gold and silver, such as foreign exchange reserves, such as talents.
In the face of the mess left by the Kuomintang, our party faced difficulties, carried out the agrarian revolution and implemented the first five-year plan ... The state also attached great importance to road construction. By the end of 1950s, the highway mileage in China had reached 250,000 kilometers, and the Sichuan-Tibet, Qinghai-Tibet and Xinjiang-Tibet highways in the western region were also opened to traffic.
1979 In the spring, an old man drew a circle on the South China Sea in China, and the development of China entered the fast lane, resulting in the Shenzhen miracle and Shenzhen speed. In 1980s, the slogan "If you want to get rich, build roads first" made people deeply realize the importance of building roads, and at this time, China's "infrastructure enthusiasts" also had a harbinger.
No matter how fast we develop, we can't forget that our country is still in the primary stage of socialism and will be in it for a long time, and our international status as the largest developing country in the world has not changed.
China has a vast territory and abundant natural resources, but being big means that there are many roads to be built. Just like online shopping in Xinjiang, it is impossible to package postal services, because the area of Xinjiang is really too big. The area of Xinjiang is equivalent to that of 16 of Korea. If you buy a product of 10 yuan online, the freight cost is 100 yuan.
Expensive freight means high cost of road construction. The land area of China is 9.6 million square kilometers. The manpower, material resources and financial resources needed to build roads that meet modern standards on such a vast land are immeasurable.
Faced with this situation, China's highway construction is to complete the basic needs first, and then optimize the highway conditions when conditions permit. Just as it was proposed at the beginning of the reform to develop the east first, so that some people can get rich first, and then the part that gets rich first will help the backward areas now. The same is true of road construction.
For remote places, it is enough that there is a way for them to see the outside world and make a living, improve their lives and increase their income through this road.
Today's development speed has further accelerated the speed of highway damage. First, the country needs to continuously build infrastructure, such as building high-speed rail, high-speed highway and reservoir.
These constructions need a lot of building materials, and the transportation of building materials depends on large trucks, which have the greatest damage to roads; Second, the development of e-commerce has greatly promoted the development of logistics. With the improvement of people's consumption level, the goods of a car go from south to north and from east to west. These moving trucks roll back and forth on the road, and the road is of course easy to break down.
Primary schools in Japan have developed steadily with little road damage.
Although Japan's land area is not large, it is almost as big as China's Yunnan Province, but it is indeed a highly developed country and the third largest economy in the world.
As a defeated country in World War II, it took Japan 20 years to move from a "developing country" to a "developed country". Subsequently, due to the signing of the Plaza Agreement, Japan gradually entered a period of stable development, and its development speed slowed down or even showed negative growth.
The land area is small and the funds are sufficient, so Japan will spend a lot of time on survey and planning before building expressways. Since we have plenty of time and are not in a hurry to work, according to the Japanese style of doing things, we should be prepared to start work and adjust our plans from time to time according to the actual situation to achieve the best results.
China has a vast territory and limited funds. At present, we can only meet the basic needs and ask for something else.
The fastest time for Japan's development was in the 1960s, when Japan was also speeding up road construction to keep pace with its economic development. In the sixties and eighties of last century, Japan's roads should be repaired frequently, but by that time, Japan should have basically completed the construction of national roads, and the economic speed slowed down accordingly. Various urban infrastructures, such as laying various pipelines, have also been paved, and the frequency of road use has decreased, so roads are rarely repaired.
China is now in the stage of accelerated development, and the roads are always running at a high speed, with high frequency of use and serious road damage, so it can only be "reworked" constantly.
Maintenance technology and maintenance cost also affect the status of asphalt roads in both countries. Although the basic process of paving asphalt roads is similar, many things in China are explored and practiced by themselves for some historical reasons.
Although China has rich experience in road construction, for asphalt highway construction, some key technologies are always different in speed and implementation.
Japan is different, because it is a defeated country in World War II and located in Asia, which has different political functions for some countries. Therefore, its development after World War II was carried out with the support and laissez-faire of some countries, and all aspects of Japan's development were helpful.
As a result, the mechanization level of asphalt road maintenance in Japan is higher than that in China, and the maintenance cost has also increased, which Japan can afford. China's asphalt road, damaged to a certain extent, can not be maintained. After all, our funds are limited, and money must be used on the cutting edge.
Now we can see that Japanese asphalt roads are very new, while China asphalt roads are always "reworked". There are many factors that cause this sharp contrast. Although China has a long history of highway construction, with a large territory, complex terrain and limited construction funds, there are many and long highways to be built now.
The comprehensive road construction in Japan is earlier than that in China, with a small area. There are not many roads to be repaired now, and the technology is good and the funds are sufficient. These factors create two completely different pictures.
Therefore, we should not look at things superficially. The national conditions of each country are different. This requires seeking truth from facts and adapting to local conditions. As China used to say in the early days of reform and opening up, "No matter whether it is a white cat or a black cat, catching a mouse is a good cat."
At present, although China's economic aggregate is huge, its per capita is still not ideal, and it still needs to accelerate its development. Limited funds, there are still many roads to be repaired, so we can only finish the basic road construction first, and the maintenance should be carried out according to the actual situation, as long as things are not delayed.
Summary:
"A journey of a thousand miles begins with a single step. If you don't accumulate steps, you can't go to Wan Li Road. " We should eat rice bit by bit and do things one by one. We will do it step by step. I believe that in the future, with the further enhancement of China's economic strength and the progress of road construction technology and maintenance skills, our asphalt road will no longer need to be "reworked" frequently, but will remain clean and brand-new.
