1. Yantai Huatong Road Engineering Co., Ltd. answers: emulsified asphalt is not used in cold mix now. Because the emulsified asphalt contains water, it is easy to break the emulsion and solidify. Moreover, because the water in the emulsified asphalt needs to freeze at low temperature, it cannot be used below 4 ℃. If you have to use emulsified asphalt mixing, that is, mineral powder and crushed stone can be added together with emulsified asphalt
cold patching asphalt is a kind of modified asphalt mixed at room temperature. If appropriate anti rutting agent and anti stripping agent are added to the cold patching asphalt, the adhesion between cold patching asphalt and stone can be effectively improved, the high-temperature fluidity, deformation ability and low-temperature brittleness of cold patching asphalt can be enhanced, and the occurrence of rutting can be reced. Yantai Huatong company is a restructuring enterprise of Longkou Transportation Bureau, formerly known as Longkou county and township highway maintenance emergency center. It is the first manufacturer of asphalt cold patching materials in China. It adopts 3000 asphalt mixing plant for batch proction, with good uniformity and complete test and detection equipment
Yantai Huatong company's elaboration on road cold repair technology:
in road maintenance engineering, compared with the traditional concept of hot and high temperature repair, cold repair is used for repair at room temperature or low temperature. The material used for cold repair is cold repair material. Specifically, asphalt cold patching material is a mixture formed by mixing unheated mineral aggregate and diluted asphalt. According to the mixing form, it can be divided into two kinds: Factory mixing and site mixing
before 1998, there was no real cold repair material in road maintenance engineering in China, only water-based emulsified asphalt material was used for room temperature repair. After 2000, Yantai Huatong company launched the first asphalt cold patching material in China with stable performance. As a high-tech proct, cold patching material has been widely used in national and provincial roads, county and township roads and municipal roads
compared with common hot mix, asphalt cold repair material is a kind of high-tech road repair material, which can be used all day. It is suitable for repairing various types of road surface in any weather and environment, such as asphalt, cement concrete road, parking lot, airport runway, bridge expansion joint, etc< The forming mechanism of asphalt cold patching material is as follows:
the strength forming process of asphalt cold patching material of Yantai Huatong company is different from that of hot asphalt mixture. The asphalt used in hot asphalt mixture is thermoplastic, while the asphalt of cold patching asphalt mixture is modified, which is not completely thermoplastic. The strength formation of cold patching mixture has a slow process. It has plasticity and fluidity ring paving and rolling, and can be squeezed to the irregular place in the pit. Under the action of driving and air, part of the solvent volatilizes, the asphalt graally thickens, the distribution between the particles of cold patching mixture is more compact, the void ratio is reced, and the bonding of mineral aggregate is more firm. As the density of the mixture increases, the soft feeling of the pavement will graally disappear, which takes 7-10 days. After that, the strength will graally increase. After about three months, the deformation and strength will graally stabilize, reaching or exceeding the performance of hot asphalt mixture after cooling. The strength of cold patching mixture consists of two parts: one is the cohesion and adhesion of the mixture formed by the interaction between modified asphalt and mineral aggregate. They make it difficult to separate the mineral particles and form a whole, and also make the mixture have high adhesion with the original surface and not easy to peel and move. The second is the internal friction resistance of the mixture after rolling e to the interlocking effect between the mineral particles. These two parts of the cold patching material constitute its initial strength and are sufficient to resist the action of vehicle load< Characteristics of Yantai Huatong cold patching material:

Recently, a & lt; The Financial Association asked all localities to shut down bitcoin mining projects; The news of, caused the hot discussion of broad netizens, make boiling on the net< so, is this mining project really unreliable? Let me talk about my opinion. First, I think it's reliable, because from the point of view of facts, there are many mining enterprises that make a lot of money by mining. So it's not appropriate for you to say that what can make money is unreliable. Second, it's not reliable. Why not? Because as the state begins to suppress virtual currency to prevent virtual currency from damaging national wealth, mining enterprises are not allowed in China. Then it's over if we go to this project again and get checked. To sum up, the previous situation, you can make money to dig the project. But now, as the state begins to crack down, it is no longer a safe project what is the specific situation? Let me share my views with you

1. Reliable

first of all, reliable is because before, people were able to make money when they went mining. It's not appropriate for you to say that a project that can make you continuous money is unreliable{ RRRRR}

the above are my views on this issue. They are purely personal views and are for reference only. If you have any different opinions, you can leave a message in the comment area for discussion

8. Continuous attack is connected
two stones with + 12 practice rate
one stone with + 5 practice rate
a necklace with level 10 (buy one, go to the blacksmith and upgrade to 10)

for additional attack
go to the three boundary order exchange office of single mission in Donghai to change a weapon, increase 30% continuous attack rate, and then change a hat or a piece of clothing, If you have a weapon with a combo rate of more than 30%, you can change the weapon, because the damage of this weapon is not high I just found a problem. One of the hats or clothes can be changed into a spiritually strong law high resistance suit. You can do mAb 150, so on.

then go to Yangguan and change into a level 50 bracelet. One is 180 trijie Ling, each with 28 combo rate, and two with 56 combo rate, However, the demon clan also has a combination of amulet and belt, which can proce a Leifa attack with 28. What we added to the weapon just now is 86 combo rate,

then the necklace hits a stone with 13 combo rate. In this way, we can achieve a combo rate of 99,

times, shoes, 3 times and 5 times of stones. Now we take 1W for each, 30000 yuan, and the cost is not high. Then we add one more combo times, I catch up with one, so the shoes are 16 times,

the remaining two positions of the necklace can hit two 5 times of stones, so the necklace can have 10 times, The total is 26 times

so far, the combo rate is 99%. The number of times is 26. The necklace can be added times or chance, which depends on everyone's preference<

amulets and belts are used for high hit,

well, the equipment is matched like this, 26 times in a row, changing cards 28 times, and adding fire to attack. It's really fun to play, especially the blood legal person has no attack power. You can output damage by this suit

The financial stability and Development Commission of the State Council has asked all localities to shut down bitcoin mining projects and crack down on bitcoin mining and trading. From the requirements of relevant national departments, in fact, it can be clearly found that the risk of bitcoin trading is really high, which not only ordinary people can't stand, but also has a destructive impact on the trading market in order to ensure the stability of our market order and the interests of investors, it is an inevitable trend to close the bitcoin mining project. Now we do not want to enter the business of bitcoin, which is not only an illegal act, but also a ruin{ RRRRR}

in the process of bitcoin hype, there is a person quite famous. This person is musk, who is the godfather of the coin circle. This year, bitcoin has fluctuated up and down in Musk's words and deeds for a long time. Especially since last month, Musk's counter attitude towards bitcoin has made the price of bitcoin experience a roller coaster fluctuation, In fact, many people have been exposed to this fluctuation< from the point of view that personal behavior can affect bitcoin transactions, there is really no guarantee for bitcoin

based on the above, it is a correct behavior for relevant departments to require all localities to shut down bitcoin mining projects. At the same time, bitcoin mining and trading are illegal now. Ordinary people should never enter the bitcoin trading market again. The risk of bitcoin trading is really greater than many people think
