Walking into the road, what catches your eye is the inky black ground, the asphalt ground with a little bit of fine mineral aggregates, the ground is smooth and elastic, and the friction has increased a lot, which is enough for the vehicle to tell the drive. Pen, fun, pavilion www. biquge。 info

"Boss, our company needs to ensure the use time and quality of the pavement, and the annual loss of the commonly used road sections in our country is about 2 cm, but we are now using the SMA structure form of red that is more commonly used in the world. Xiao Xu beside him talked eloquently, it seems that he has learned a lot about the knowledge of highways recently.

Si Fan listened quietly, and the system in front of him had already given him a lot of hints.

After all, he is engaged in architectural design, pavement design is not within his knowledge, and now he knows that SMA structural pavement is a structure that began to be promoted in the mid-to-late nineties, and in fact it has proved to be very durable.

The so-called SMA structure is to adjust the mix ratio of asphalt mixture, increase the proportion of coarse aggregate, add fiber stabilizer to form a special structure, and greatly extend the service life under the condition of ensuring that the performance of the use does not change too much.

This is also where Si Fan is satisfied. Because the quality here can still be guaranteed after using the SMA structure, and the durability time is also 17 years according to the system according to the test.

That's 15 years over the average age, and that's enough.

Si Fan also knew that this time the asphalt concrete pavement was used. And it's a rolling way.

Asphalt concrete mixture is prepared by hot mix hot paving method, its road properties are better, so the requirements for preparation process and raw materials are also higher, and the equipment used is that people can often see the huge roller from the road surface like a stone rolling through, and the mixture must go through this process to be considered to be completed.

Such a road surface is smooth, compact, less dusty, and has a certain roughness, so it has better driving comfort and appearance, and has good aging resistance, wear resistance, temperature stability and the ability to resist driving damage. The service life is generally long, and petroleum asphalt is used as a binder, and the overhaul life is often more than 15 years.

Now the inspection of the pavement materials are exquisite, the ratio is appropriate, and the materials are not problematic, such pavement can really be used for fifteen years.

As for the roads in the city now.

It can be used for five years is already high-quality. Roads that are renovated every year abound.

Smelling the road surface that exuded a strong smell of asphalt, Si Fan's mood was much better, which was one of the few projects that Skynet used other engineering teams to carry out construction.

And it is an unexpected surprise to be able to ensure the quality, because the price of the project given by Si Fan is just in the middle of the profit, but the profit range is not very high, if it is a normal construction, the company's normal profitability, then there is no problem at all, in the eyes of many people, it is an urgent normal project.

But Si Fan is worried, worried that he will encounter the legendary connotation project, and he will clean up the project little by little, of which the cost of construction is less than 30%, so it is impossible to complete this project, because Si Fan has calculated the price, and after removing all the costs, the profit is about 20%, and the entire project can be completed in a month if it works overtime.

"Let's move on. By the way, tell me how you arranged the overseers, how to arrange all the preparations, the construction of this road is not cheap. Si Fan said.

This road is a serious road, and it is of a high standard. All of them are beyond the usual standards of those who build.

Xiao Xu said with a modest smile: "Boss, don't worry." I will come over as long as I have time these days, and I believe that there will be no big problems in terms of materials and construction. ”

He said confidently. It's just that Si Fan pouted, he knew too well how much of it was boring, if he went directly to the office after graduation, he might not have been exposed to so much, but after working on the front line for so long, he had already discovered that this industry was up and down from top to bottom, big fish eat more, small fish and shrimp also have their own way of survival, everyone is profitable, everyone takes advantage, but the project is scrapped.

But it doesn't matter, they have already set up a good way, and when the project is scrapped, they can pave the road again, and a fish can be eaten a dozen times, and the big guys are all fat and oily.

It's just that this kind of thing Si Fan definitely doesn't want to appear in a place under his control, and even now, he doesn't dare to guarantee the condition of the road.

"It's still early. Half of the road has been paved for more than 10 days, so let me see what you have done. Si Fan said.

Xiao Xu led the way, and the two of them walked quickly on the road. At this time, Si Fan was completely handed over to the Skynet system, because the current road conditions all looked the same. At least superficial scenery. But what is inside still depends on the detection of the system.

For more than ten minutes, the ground they walked quickly was qualified, Xiao Xu had a little smile on his face, and he was happy with Si Fan's walking speed.

This is a rare project for him to actually follow Si Fan's instructions. The company's decoration team is expanding every day, and even has reached the national scope, but the grade of decoration has also improved again and again, almost all the high-end decoration is round, and the various building materials suppliers and suppliers are attached to the command of Skynet Company, they really want to eat this bowl of rice.

If you want to enter the list of Skynet's procurement list, what you must do is quality, and according to the quality and brand, Skynet will take the initiative to set prices, if the previous manufacturer's price is too high, Skynet will re-evaluate, if you can accept it, you will continue to cooperate, if you can't accept it, you will completely stop cooperating.

This is the way of doing things of Skynet, and naturally it has also improved some of the products with high quality, but the price has been barely guaranteed.

After strict quality control, it is to raise the price of some enterprises so that they can make profits at the same time.

On the current road, Si Fan almost wanted to believe that they would build the road well, at least it was a rare thing to complete under strict supervision.

But at this time, the system's prompt appeared, and the moment the prompt appeared, Si Fan's heart was not even filled with anger, but ridiculous.

Hidden quality hazards were found, the quality of asphalt was reduced, the quality of aggregate was reduced, the thickness of laying was greatly reduced, and the service life was greatly reduced. ”

It was just a momentary hint, and the hope that had just risen in Si Fan's heart had completely crashed.
