The process of laying an asph alt road

The asph alt road has long become a familiar part of the modern landscape, which few people pay attention to. A network of roads stretched across almost the entire earth's firmament, improving the speed of communication between people. Watch how, for example, they pave the road. On the one hand, such work can hardly be called high-tech. On the other hand, knowledge of some of the nuances in the creation and operation of modern roads contributes not only to their strength and durability, but, in some cases, directly affects safety while driving.

A little digression into history

Asph alt has been known to our ancestors since ancient times. For example, the Dead Sea was called asph alt, and this name has survived almost to this day. The deposits that were there were used not only for road construction, but also in shipbuilding and even mummification.

It is especially interesting to note the Spaniards, who drew attention to the wonderful properties of the bitumen lake Peach Lake, on the island of Trinidad. Natural asph alt mined in this place is still popular all over the world. The needs of mankind, which can providethis lake, scientists have estimated at about 400 years old, but there are 15 more deposits. The cover of the Paris Royal Bridge can rightly be considered the first paved road. In its creation, a bitumen-mineral mixture was used. "Fashion" has come to Russia. So, in St. Petersburg, several road sections were asph alted. But the Americans really turned around starting in 1876.

Where does the road begin

In what order will the road be paved? Of course, it all starts with planning and design. They take into account the interaction with other roads, drainage systems, traffic lights, crossings and many more nuances.

Preparation

This is perhaps the most time-consuming and responsible operation of the process. The quality of an asph alt road directly depends on the correct decision-making and control over the execution of preparatory work. According to their specifics, preparatory measures differ depending on environmental conditions. In the city, they may not be so labor-intensive, but outside the city there are options: cutting down trees, studying the presence of groundwater and other factors. For example, if you do not take into account the occurrence of groundwater, then the asph alt road may be washed out and a collapse will occur.

The process itself is as follows: depending on the conditions of the relief, sand is added or, conversely, the excess earth is cut off with a bulldozer. The next most important point is to give strength and hardnessfoundations for the road. There may be several options. Crushed stone is poured with sand, and the fraction of crushed stone matters. Large crushed stone is used where a serious load on the road surface is expected, small - on the contrary. Reinforced slabs may sometimes be used.

Side curbs serve several purposes at once: they hold the roadway together, and they also serve as a guideline in its creation. After filling the "cushion" of sand and gravel, it must be tamped. It is impossible to carry out such work carelessly, since the quality of the asph alt road depends on the strength of the foundation.

The moment of acceptance of completed work

And here comes one of the most important moments - the acceptance of hot asph alt. The very base of the road is properly cleaned before this and spilled with hot bitumen, which is rubbed over the entire area. The arrived hot asph alt usually falls out into one heap and is evenly distributed by hand with shovels over the entire area of the future coating. Following the road workers who distribute the asph alt, there are people with an interesting tool that vaguely resembles a mop, or, as the builders call it, a “mashka”. Their task is to level the laid asph alt as much as possible.

The final chord is the paver, which slowly but surely completes this production process. This is a description of the manual way of laying asph alt. There is a second, no less effective, with the participation of two special road-laying machines. The first distributes asph alt, replacing all manual labor. Secondis a paver that, following the first, brings the work to its logical conclusion.

Some observations

Watch how the roads are paved. Sometimes you can see very interesting things. For example, when laying occurs in rain and severe frost. Because of this, the quality of the asph alt deteriorates sharply, because it is impossible to do such work in bad weather.

Heavy trucks break up roads mercilessly, especially in cities where the paved road is not designed for such a load.

And, as they say in medicine, prevention is better than a long and exhausting treatment. This statement is also true in relation to the rules for the operation of the road surface.
