Whether it is a paver or an asphalt concrete mixing plant (referred to as a bitumen mixing plant), this is almost a necessary equipment for high-grade highway construction, especially in high-grade highway pavement construction.

A paver is a machine that spreads building materials evenly onto the road surface. That's right, the core function of the paver is actually the word "uniformity". High-grade highways are distinguished from ordinary highways by an important index, which puts forward higher requirements for the smoothness of the road surface. In order to achieve a relatively high flatness, whether the filling material can be "evenly laid" is the key to the problem.

Before the advent of pavers, road construction was most commonly used in a method known as the "ground mixing method", in which the fill material was piled on the roadbed and then compacted and leveled either manually or with ordinary machinery.

The disadvantages of this method can actually be imagined by ordinary people, the uneven laying of the filler will inevitably lead to uneven compaction, and once the compaction is uneven, it is naturally difficult to ensure the flatness of the road surface in the future.

For example, we often see some low-grade construction in the early years, when the road is just repaired, the flatness looks good, but after a period of time, when the natural settlement of the roadbed is completed, some of the road surface begins to potholes and waves. This is a very common building problem in road construction in the early years, and this is actually the reason for this common building problem.

The emergence of paver is a good solution to this common problem of construction, and compared with other construction methods, the use of paver paving, the construction speed can also be greatly accelerated, so in the construction of high-grade highways, this machinery is widely used.

After introducing the paver, let's talk about the asphalt mixing building. Asphalt mixing buildingAsphalt mixing plant, as the name suggests, is a kind of equipment used to produce asphalt concrete. If pavers are very important for highways, then asphalt buildings are even more important. After all, the role of the paver can be replaced by other construction techniques, but the role of the asphalt mixer cannot be replaced at all.

As we all know, there are two most common forms of pavement on modern roads. One is the ordinary cement concrete pavement, and the other is the asphalt concrete pavement, which is commonly known as the "asphalt road". These two types of pavement have their own characteristics and strengths. Cement concrete pavement is more wear-resistant, theoretically has a longer service life, but this pavement has a fatal flaw, that is, this pavement is the so-called "rigid pavement", the car runs on this pavement, the speed should not be too fast, otherwise not only people are easy to feel uncomfortable, but also the wear and tear of the vehicle is also great.

The characteristics of asphalt concrete pavement are just the opposite, which is a kind of "plastic pavement" or "flexible pavement". Asphalt concrete pavement may not last as long as cement pavement, but it is better for the car to run comfortably on it, and it is also more conducive to increasing the speed of the vehicle.

It is precisely because these two types of pavement have their own characteristics, so everyone also has their own focus when choosing. For example, on the roads in the city, of course, you don't need to be fast, in fact, most of the time, you can't go fast if you want to, so when you do this kind of pavement, you usually choose cement pavement. As for highways, asphalt concrete pavement is definitely preferred.

Li Huayong just mentioned these two kinds of equipment to Lu Yuquan, and it is not unusual to say that these two kinds of equipment are original, for example, in later generations, these two kinds of equipment can be seen almost everywhere in any place where roads are built.

However, the future generations are the future generations, and in this day and age, these two devices are still rare. Originally, "rare" was not at all, after all, the construction of domestic highways has just begun, and it is normal for this kind of equipment to be rare. The most important thing is that these two types of equipment cannot be produced in China at present.

In Li Huayong's impression, the first paver in China with a paving width of more than 10 meters seems to be produced after 2000, and when it first came out, it still did not come out with an infrared automatic leveler, and each paving must also hang steel strands for manual leveling.

As for the asphalt building, Li Huayong must tell the truth, even when he crossed, Li Huayong knew that the relevant equipment could already be produced in China, and the price was still very cheap, but Li Huayong himself had done the project, he really had never used domestic equipment.

This is actually the reason why Lao Lu smiled bitterly when he heard Li Huayong mention these two devices. Because these two kinds of equipment not only need to be imported, but more importantly, the price is expensive.

Probably before Li Huayong crossed, there were more 4000 and 5000 type leaching plants used on the highway (the kind with a production time of 45s per pot and a production capacity of about 140t/h). There is a big difference between the price of domestic and imported ones. The price of 4000 to 5000 domestic products is about 4 million to 5 million, and the imported ones are twice as expensive, generally more than 10 million.

2016 is this price, don't take it for granted that this era must be cheaper. The market of construction machinery is not like this, and the price can be that in later generations, it is mainly to take advantage of the domestic equipment. Similar to most "Made in China", as long as we Chinese can produce something, the price of similar products will immediately fall.

Li Huayong remembered that he had just joined the work in his previous life, and it was less than 2000, when the unit gritted his teeth and imported a complete set of pavement equipment from Italy, in addition to a bitumen mixing building and a paver, there were also a few more asphalt pavement special rollers. Just those few things, it cost tens of millions of units.

It is precisely for this reason that Li Huayong understands why Lao Lu is embarrassed now.

The reason why Lao Lu is looking for you today is because he just recovered a few million yuan from the rotten boy blue, and he came to discuss whether he needs to buy additional equipment. But you're a good guy, you want to buy equipment, but as soon as you open your mouth, it's a business of tens of millions. How does this make people react all at once?

It's just a matter of money, Li Huayong believes that with Lao Lu's strength, he can spend 600 million to acquire "Kowloon Construction" just now, and if the Lin family helps again, tens of millions should still be difficult for him.

But the key problem now is that pavers and asphalt buildings are not like excavators, which can be used as soon as they move to the mainland, and they can quickly see benefits. Although it is said that there is likely to be a piece of "self-reserved land" on the Yangpeng Expressway, even if it is a possible "self-reserved land", it will not be able to start construction immediately. And even if construction can start this year, if you want to use these equipment, it will have to wait until after the construction of the roadbed is completed.

Lao Lu thought about it for a long time, and took a deep breath: "Xiao Li, let me think about this matter." ”

Li Huayong smiled and said: "Such a big thing, of course, needs to be considered clearly." But Uncle Quan, I think it's better for you to prepare for this kind of thing as soon as possible, after all, for a construction machinery company, this kind of equipment is the core competitiveness. ”

Lu Yuquan looked at Li Huayong meaningfully: "It seems that Xiao Li's ambition is quite big, are you so optimistic about the mainland's highway market?"

Li Huayong was happy, and said in his heart, do you still need to say this? But some words are really difficult to explain to Lao Lu. Indeed, if you are not a time-traveler, then in this era, it is really impossible to imagine what kind of infrastructure construction China will have in the next few decades. China's highway network has been perfected from scratch in just a few decades.

Not to mention that Lao Lu is not a traverser, even Li Huayong, a reborn person, sometimes feels incredible in retrospect.

"Uncle Quan, let me tell you, my ambition is not only these, now I just want to pave and asphalt the building, in the future, if possible, I am also ready to have my own bridge erecting machine, if it is to do tunnel engineering, then I also want to have my own shield machine...... If I keep talking, you should criticize me for being too ambitious. ”

It was precisely because he couldn't explain it that Li Huayong had no choice but to use this kind of rhetoric to fool around. Lao Lu laughed, but finally thoughtful:

"I don't know where your faith comes from, but there's one thing you are right. ”

"Oh, that sentence?"

"If we Xiangjiang people want to develop in the mainland, these things are our core competitiveness. ”
