In the development process of modern society, from the original gravel road, cement road, to the now widely used asphalt roadAs a polymer material, asphalt is soft and plastic, and there is a certain distance between the molecules in the middle after curing, so that it can withstand a lot of load, and there will be no cracks due to thermal expansion and cold contraction.
The advantages of asphalt are obvious, but the cost is much higher than that of cement pavement, but you may not be able to imagine itNext to a seemingly ordinary stinky ditch, there is a natural asphalt treasure - asphalt lake.
Bitumen is mainly a product of distillation, which is divided into tar distilled coal coke asphaltIt is not widely used because it is highly toxic and easy to soften in summer and brittle in winter.
And we see asphalt pavement everywhere,It is a black-brown mixture produced by distillation of petroleumIt is often used in waterproof, moisture-proof and corrosion-proof places, such as roofing, ground, waterproofing, wood, pavement and other places.
Compared to cement pavement, asphalt pavement has too many advantagesFor example, the shear resistance and deformation resistance are large, the adhesion is strong, the temperature will not be affected and broken, the waterproof, the aging resistance is strong, the construction is convenient, and the construction can usually be completed within one day, and it can be opened to traffic in a few hours.
It is also very beneficial from the perspective of driving safetyOn the cement pavement, when it rains on a cloudy day, the braking distance increases significantly, which is not conducive to braking, while asphalt does not have this problem.
And there is a kind of smooth and comfortable driving on the asphalt road, the noise is not so big, and the construction and maintenance is very convenientIf there is a problem with the road in the future, it only needs to be chiseled and resurfaced, which will not affect the opening time.
The cement road is not enough to see in comparison, the laying is slow, and the maintenance and watering take a week. It is easy to break and potholes for a long time, and the service life is shortIf there is a problem, it is also troublesome to repair it, so this is also the reason why asphalt roads are gradually becoming popular.
With its superior performance, asphalt road not only provides a smoother driving experience for vehicles, but also greatly reduces road wear and tear caused by natural factorsBut the price is too high, and the cost is basically twice that of the cement road.
And in such a place, there is a natural asphalt lake, and the stock here can provide about 200 years of asphalt for humans!
In a small corner of the Caribbean, there is a magical place tucked away-Beech Lake, formed from a strong **, caused the earth's crust to break and the surface magma gushing out, thus forming this peculiar lake.
The main material of Biqi Lake is bitumen and other rock minerals, and the whole surface of the lake is like a huge black rock mass, and the bitumen reserves of Biqi Lake are amazingExperts estimate that at least 15 million to 26 million tonnes of ** are stored underground in this area.
These ** asphalt will become the world's inexhaustible natural gift, this area is only 0With a depth of about 90-10 meters, the 46-square-kilometer Lake has a treasure trove of bitumen that can be extracted naturally by humans for about 200 years.
In addition to the wealth that asphalt mining can bring to the country,The natural geography has also become the best promotion of this area, and countless tourists come here just to see the magic created by nature with their own eyes.
When you step into Piech Lake, you will be greeted by a layer of sparkling black oil on the surface of the lake, which shines like silk and shines dazzlinglyThe surrounding vegetation is thriving, adding to the pleasant view of the lake.
There are also many magical legends that circulate in this lakeOne of the theories is that the lake ** has a mysterious island overgrown with a name called"Beech Tree"The branches of these trees are light and flowing, like feathers.
When night falls, the trees sparkle as bright as a full moon, and many consider them to be the guardians of the lake monsters, alluding to the mystical magic that Lake Beech possesses.
And the asphalt paving scene that everyone usually sees, the asphalt is hot and sticky and smells bad, making people unable to get close, but in Beech Lake,You can get up close and personal with asphalt, feel what it's like to walk on asphalt, and experience the mystery and wonder of nature.
This hidden lake of BeechIn addition to asphalt, there are other historical gems hidden in the area, and there is also an abundance of oil beneath the surrounding rock formations of Lake Pitsch.
This discovery once again made the land appreciate in valueBitumen and oil are scarce commodities that countries around the world are vying for, but at Lake Pitch they are both.
The bitumen from Lake Biech is different from the bitumen found in other areas that have been found so farBeech Lake asphalt is inherently very viscous, and it was found to be the most permeable to other asphalt in terms of permeability.
So in addition to being able to be used as a normal road paving, the asphalt from Lake Biech can also be used as a waterproofing materialBecome a sought-after treasure in the field of architecture.
There are also historical sites under the bed of Lake BeechThese represent the evolution of civilization in different periods, and they have become another shocking discovery of Beech Lake.
The most soil is the bones of animals and peopleThese things that prove that this land has been clear have made countless people want to understand this mysterious land even more.
The shocking discovery was the discovery and excavation of the remains of the Native Americans who once inhabited Lake Pitsch as the original inhabitantsThrough the excavation of traces, it was found that they once regarded this land as a punishment from heaven to warn future generations.
In addition to Lake Beech, there are other famous bitumen deposits in the world, such asThe La Brea Asphalt Pit in Los Angeles is one of the ones still being mined, and this asphalt pond has been the subject of research by scientists since the Ice Age.
In China, there are also abundant natural asphalt mines in the Guangyuanmen Mountain area of Sichuan, where the asphalt ore reserves exceed 10 million tonsTherefore, it is called "China's first asphalt mine" by experts.
Asphalt is particularly important for national construction, although our country has asphalt mines, but not enough to support the asphalt road paving required by the country, so we should pay attention to these sustainable natural asphalt mines, which is a gift from nature.
The story of Lake Beech is not over, it is one of the largest asphalt lakes in the world, and there are even more mysterious treasures hidden behind it, providing great support for the local economic development and providing valuable energy resources for the world.
The mystical aura exuded by Lake Beech attracts people from all over the world to explore and appreciate it as a place of both natural wonder and economic valueWe need to think deeply about the environment and protect these great resources.
