What is the difference between bitumen and modified bitumen, and which one is better?

What key points should be paid attention to when feeding emulsified asphalt equipment? When it comes to emulsified asphalt equipment, I don’t know how much you know about it? What should you pay attention to when adding materials?
The black anti-static tweezers grinding wheel of the emulsified asphalt equipment does not have a heated collet. Before use, you must add the appropriate amount of diesel and let the black anti-static tweezers circulate for 3 to 5 minutes to generate heat (the temperature after operation is 80 ~100 degrees) open the stop valve on the oil delivery pipe to drain the diesel engine in the engine. The temperature of the black anti-static tweezers grinding wheel must be around 80 to 100 degrees before the material can be loaded and put into production. If there is a heated collet, the grinding wheel must be heated before starting, and then the material is loaded and put into production.

With the rapid development of highway construction and the increase in demand for asphalt, barreled bitumen has been widely used for its convenient transportation and easy storage. In particular, most of the high-performance imported bitumen used in high-grade highways is in barrel form, which requires an bitumen melter equipment with fast melting speed, clean debarreling, and prevention of asphalt aging.
The upper part of the debarreler of the bitumen melter equipment is hotter, and each barrel is directly heated by the heat transfer oil coil. The barrel wall directly bears the heat radiation of the heating coil. The asphalt is cleanly and sensitively debarreled, and there will be no waste of asphalt hanging barrels. According to the principle of layered heating, four-layer heating technology is adopted, with single inlet and single outlet of heat transfer oil, and high thermal efficiency of heating; at the same time, the waste heat of combustion exhaust gas is used for secondary heating, and power is effectively used; the debarreler body is insulated with high-quality rock wool material. It is suitable for various types of imported and domestic barrels, and the deformation of asphalt barrels will not affect production.

The modified asphalt equipment produced by Sinoroader can produce SBS, rubber powder, SBR, and PE modified asphalt manually and automatically. Some of its configurations and uses are as follows:
1. Filter: The specially made asphalt filter can effectively filter impurities and foreign matter in the high-temperature matrix asphalt to prevent damage to subsequent equipment.
2. Matrix asphalt heater: The spiral plate or shell and tube heat exchanger is used to quickly heat the matrix asphalt through heat transfer oil to meet the needs of the production process. Heating in a sealed tank avoids the aging of asphalt due to long-term high-temperature heating and exposure to the air. The sulfide produced during the production process is quite limited, reducing environmental pollution.
3. Modifier air delivery or spiral addition system: The modifier manually poured into the pouring hopper is delivered to the asphalt batching tank by wind or spiral. It can be equipped with a metering system.
4. Stabilizer automatic or manual addition system: It can be equipped with a metering system.

Modified bitumen equipment uses modified bitumen colloid mill. Its blade has high hardness, high linear speed of the moving disk, and the gap can be adjusted to 0.15mm. It is suitable for processing various polymer-modified bitumens, such as SBS, PE, EVA, etc.

I believe everyone is familiar with the relevant knowledge about modified bitumen equipment. As users continue to increase its application, we have also talked about it a lot in the above articles and learned that it is mainly engaged in the production of modified bitumen. Production, in order to further enhance users’ understanding of it, professionals summarize its relevant characteristics as follows:

Asphalt mixture mixing equipment is a factory-style complete set of equipment that mixes dry and heated aggregates of different particle sizes, fillers and asphalt according to the designed mix ratio at a specified temperature into a uniform mixture. It is widely used in high-grade highways and urban roads. , airports, docks, parking lots and other engineering construction. It is a key equipment for asphalt pavement construction, and its performance directly affects the quality of asphalt pavement.
Generally, there are two types of asphalt concrete mixing equipment: intermittent type and continuous type. The continuous process flow is simple and the equipment is simplified. As for the intermittent forced mixing equipment, due to the secondary screening of aggregates, various components are measured in batches, and forced stirring and mixing can reliably ensure gradation, and the measurement of powder and asphalt can also achieve very high accuracy; so the mixing equipment The asphalt mixture produced is of high quality and can meet various construction requirements.

Synchronized gravel sealing is to use special equipment, namely a synchronous gravel sealing truck and bonding materials (modified asphalt or modified emulsified asphalt) to be spread simultaneously on the road surface, and then formed into a single layer through natural traffic rolling or tire roller rolling. A layer of asphalt gravel wearing layer, which is mainly used as the surface layer of the road, and can also be used for the surface layer construction of low-grade highways.

Before use, please check whether the position of each valve is accurate and make preparations before work. After starting the motor of the asphalt spreading truck, check the four heat transfer oil valves and air pressure gauge. After everything is normal, start the engine and the power take-off starts to work. Try running the asphalt pump and cycle for 5 minutes. If the pump head shell is hot to your hands, slowly close the thermal oil pump valve. If the heating is insufficient, the pump will not rotate or make noise. You need to open the valve and continue to heat the asphalt pump until it can operate normally.

Asphalt spreading trucks are used to spread the permeable oil layer, waterproof layer and bonding layer of the bottom layer of asphalt pavement on high-grade highways. It can also be used in the construction of county and township-level highway asphalt roads that implement layered paving technology. It consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, a combustion system, a control system, a pneumatic system, and an operating platform.

We have conducted in-depth research on asphalt distributors and have accumulated a lot of production technology experience. We have conducted professional and in-depth research on some problems existing in the market to provide convenience for everyone in future production applications.
Every time when spraying asphalt, the asphalt distributor does not spray asphalt. Troubleshooting. The asphalt distributor does not spray asphalt. It is a common fault. The following teaches you how to solve the problem of not spraying asphalt.
1. No asphalt spraying
Analysis of the reasons may be the following reasons:
1. Is the asphalt pump working?
2. Are the valves adjusted correctly?
3. Is the pump or pipeline blocked?
2. Troubleshooting method
1. Check whether the hydraulic system is working properly?
2. After adjusting the valve position, the asphalt distributor must be cleaned to avoid pipeline blockage when used next time. Because the asphalt distributor has different high and low configurations, it can spread various high-viscosity and high-temperature modified asphalts and rubber asphalt in high configuration. If you mistakenly use a low-configuration asphalt truck to spread this type of asphalt, you must spray the asphalt inside the entire vehicle clean after the first use. After spraying, in order to leave no residual asphalt, you can use waste diesel to clean it. Our company’s vehicles are equipped with air cleaning and gravity cleaning devices. Diesel cleaning is a reliable cleaning method.

Modified asphalt equipment is a widely used asphalt equipment. Now its ultra-high performance has been widely praised by users. However, we must first use the modified asphalt equipment safely to fully demonstrate its performance. So how much do you know about the safe use and operation of modified asphalt equipment? Today, Sinoroader will explain it in detail:
1. Placement: The modified asphalt equipment should be placed on a flat place, and the front axle wheel should be fixed with sleepers and the tires should be dangling to ensure that the machine does not move around during operation.
2. Check regularly whether the mixer blades are deformed and whether the screws are loose.
3. Check whether the running direction of the mixing barrel is consistent with the arrow. If not, please replace the positive and negative poles of the wiring.
4. Before powering on, check for empty vehicle trial operation, check for leakage, and check the idling of the mixing barrel. The normal speed is about 3 times faster when the empty vehicle is full. If the speed is wrong, stop the car for verification.
5. If the asphalt material is stopped for one hour after mixing, clean the mixing barrel, pour in clean water, and clean the mortar. Then drain the water, remember that there must be no water in the bucket to prevent the formula from changing, and even rust on the pages and other links. During use, everyone should pay attention to some small links to avoid unnecessary losses in their work.

Here is an introduction to the knowledge on construction quality control of modified rubber asphalt equipment. Let’s introduce this knowledge from three aspects. The details are as follows: The viscosity of the modified asphalt mixture of modified rubber asphalt equipment is relatively high, and the construction temperature of each process is The construction temperature requirements are higher than those of ordinary asphalt mixtures.

Before use, please check whether the position of each valve is accurate and make preparations before work. After starting the motor of the asphalt spreading truck, check the four thermal oil valves and air pressure gauge. After everything is normal, start the engine and the power take-off starts to work. Try running the asphalt pump and cycle for 5 minutes. If the pump head shell is hot to your hands, slowly close the thermal oil pump valve. If the heating is insufficient, the pump will not rotate or make noise. You need to open the valve and continue to heat the asphalt pump until it can operate normally.

For the relevant knowledge of modified asphalt equipment, we have more or less introduced it in the above articles. I believe that most users also have some simple understanding of it. Today we also mastered:
In order to meet the different requirements of customers, the configuration and process of the equipment produced by the manufacturers of modified asphalt equipment are diversified. There are fixed production types, mobile types, and imported main machines, but the imported main machines are expensive, so most customers configure domestic pipeline emulsifiers or colloid mills. In terms of the degree of automation, there are fully automatic production and semi-automatic production. Regardless of the form of production, each has its own advantages and disadvantages. What kind of process and configuration is used depends on the annual production volume and the customer’s requirements for equipment, product performance requirements and other factors. I hope that these introductions can help users choose to a certain extent.

Preparation items for micro-surfacing slurry sealing: materials, construction machinery (micro-surfacing paver) and other auxiliary equipment.
The micro-surface slurry seal requires emulsified asphalt and stone that meet the standards. The metering system of the micro-surfacing paver needs to be calibrated before construction. The production of emulsified asphalt requires asphalt heating tanks, emulsified asphalt production equipment (capable of producing asphalt content greater than or equal to 60%), and emulsified asphalt finished product tanks. In terms of stone, mineral screening machines, loaders, forklifts, etc. are needed to screen out oversized stones.
The tests required include emulsification test, screening test, mixing test and the equipment and technical personnel required to do these tests.

Bitumen emulsifier is a surfactant. A surfactant is a compound that reduces the surface tension between two liquids, a gas and a liquid, or a solid and a liquid. Surfactants are mainly used in: detergents, detergents, fabric softeners, wetting agents, emulsifiers, foaming agents, dispersants, adhesives, etc.

From the current point of view, road construction machinery has bottomed out and asphalt meltering equipment has risen rapidly. In recent years, highway construction and maintenance departments have a strong awareness of using asphalt mixing equipment, especially in developed coastal areas such as Beijing, Shanghai, Jiangsu, Zhejiang, etc. In addition, these regions have a fast economic growth rate, relatively developed industry, and strong comprehensive economic strength. Therefore, the consumption of asphalt mixing equipments in these regions has always been at the forefront of the country. With the rapid development of highway construction and the increase in demand for asphalt, barreled asphalt has been widely used for its convenient transportation and easy storage. In particular, most of the high-performance imported asphalt used in high-grade highways is in barrel form, which requires an asphalt meltering equipment with fast melting speed, clean de-barreling, and can prevent asphalt aging. my country’s highway construction has achieved remarkable results, among which mechanized production has contributed greatly. Different types of asphalt mixers and bitumen meltering equipment are selected for the characteristics of large highway pavement construction and tight construction period. With the rapid development of my country’s economy, the further extension of expressways, and the large-scale development of western construction, the central and western regions have become new investment hotspots. While paying attention to the market in the developed eastern regions, domestic road construction machinery manufacturers have also increased their efforts to develop the central and western markets, creating new highlights for the domestic asphalt mixing plants consumer market. In summary, my country’s asphalt mixing plant sales market has begun to move westward with the westward movement of investment hotspots. As the market center of gravity gradually shifts westward, the market in the western region is gradually heating up. The self-heating integrated structure, hot air barrel melting and bitumen barrel flipping technology in the asphalt barrel removal equipment are our company’s self-heating integrated structure. The thermal oil furnace used in the old equipment is perfectly integrated with the asphalt barrel removal equipment body, which reduces the volume of the entire set of equipment, greatly reduces equipment investment, saves equipment space and transfer transportation costs.

Precautions for checking emulsified asphalt equipment
Sinoroader emulsified asphalt pavement engineering common equipment, now has gradually been widely used.
We all know that before any equipment is used, the equipment should be preliminarily inspected to check whether the installation is normal, and then put into use. The use of modified asphalt modified asphalt production equipment can also extend the peak season. The modified asphalt and stone water machine can be mixed with wet stone to form a continuous film under the surface conditions of low-temperature asphalt and stone. The viscosity of the asphalt is low and the viscosity of the emulsified asphalt is low. Wet film below 10 degrees.

There are many types of emulsified asphalt (composition: asphaltene and resin) equipment. Emulsified asphalt (composition: asphaltene and resin) equipment can be divided into intermittent operation type, semi-continuous operation type, and Continuing the three operating types, what is the knowledge about different types of emulsified asphalt equipment?

1 Common diseases of asphalt pavement
There are nine phenomena of early damage to asphalt pavement: rutting, cracks, and potholes. These diseases are the most common and serious, and are one of the common quality problems of highway projects.
1.1 Rutting
Rutting refers to the longitudinal strip grooves on the road surface along the wheel tracks, with a depth of more than 1.5cm. Rutting is a strip groove formed by the accumulation of permanent deformation of the road surface under the repeated action of vehicle load. Rutting reduces the smoothness of the road surface. When the rutting reaches a certain depth, due to the accumulation of water in the rutting, it is easy for cars to slide and cause traffic accidents. The main reasons for rutting are unreasonable design and serious overloading of vehicles.
1.2 Cracks
There are three main forms of cracks: longitudinal cracks, transverse cracks and mesh cracks. When cracks occur in asphalt pavement, water seepage occurs, which harms the surface layer and base layer.
1.3 Potholes
Potholes are common early diseases of asphalt pavement, which refer to the road surface being damaged into potholes with a depth of more than 2cm and an area of ??more than 0.04㎡. The main reason for the formation of potholes is that the oil used in vehicle repair or motor vehicles seeps into the road surface, polluting the asphalt mixture and causing it to loosen. The pits are gradually formed by driving and rolling.

In our daily life, we can often see emulsified asphalt equipment. Its appearance has brought us great convenience. So what is the difference between its modification process? Below, the editor will give you a brief introduction to the relevant knowledge points.
1. Emulsified asphalt equipment first emulsifies and then modifies: This is a relatively simple way to make modified emulsified asphalt. The production process is to grind hot asphalt and emulsifier soap together through a colloid mill to make ordinary emulsified asphalt, and then add latex-like modifiers to the emulsified asphalt through mechanical stirring to make modified emulsified asphalt. The characteristic of this method is that it does not require high equipment.

Modified material bitumen stripper, if the definition is simple, is an bitumen stripper. If described in detail, modified materials such as rubber powder or other fillers are added to the bitumen stripper, or an bitumen stripper is used to Block chemical substances such as photooxygen catalysis. The first is to change the chemical composition of the bitumen stripper, and the second is to use modified materials to equip the stripper with a certain spatial network structure, thereby improving its performance. Modified bitumen strippers mainly include vulcanized rubber and thermoplastic polyurethane elastomer modified bitumen strippers, plastic and anti-corrosion coating modified bitumen strippers and polymer modified bitumen strippers.

In order to better play the role of slurry seal vehicles, this article explains the matters that should be noted from the aspects of the scope of application, type and material selection, construction technology, common diseases, etc. of slurry seal vehicles.
The slurry seal vehicle is thin in thickness and mainly plays the role of waterproofing, anti-skid, wear-resistant and improving the appearance of the road surface. In the pavement structure system, it can only serve as a surface protection layer and wear layer, but not a load-bearing structure. It is widely used in the construction and maintenance of highways. Practice has proved that the slurry seal can also play an important role by reasonably selecting the thickness and type of the slurry seal and strictly controlling the construction technology and quality.
(1). The scope of application of slurry seal vehicles includes the following aspects:
1. When the pavement damage index of expressways and first-class highways is evaluated as medium and below, or the pavement damage index of second-class and below highways is evaluated as secondary and below, when medium repair and overlay measures should be taken, slurry seal can be selected.
2. When the pavement driving quality index of expressways and first-class highways is evaluated as medium or below, or the pavement driving quality index of second-class and below highways is evaluated as second or below, medium repair and overlay measures should be taken to improve its flatness, and slurry seal can be selected.
3. For sections of expressways and first-class highways with insufficient anti-skid capacity (SFC<40), or sections of second-class and below highways with insufficient anti-skid capacity (SFC<33.5), measures such as adding overlays should be taken to provide anti-skid capacity of the road surface. 4. Anti-skid layer and waterproof protective layer used for third- and fourth-class highways to improve the appearance of the road surface.

Abstract: Asphalt melting equipment is one of the indispensable equipment in modern road construction. Its main function is to heat a large amount of cold hard asphalt to a suitable working temperature at the construction site. Advanced asphalt melting equipment can greatly improve construction efficiency, reduce human resources and time costs, and ensure pavement quality at the same time.

The difficulty of emulsified bitumen equipment itself, because general bitumen also has different classifications, in the production and processing of emulsified bitumen equipment bitumen concrete, it is necessary to pay attention to whether the common raw materials are the common bitumen and ensure the quality. Check the black antistatic tweezers of emulsified bitumen equipment asphalt concrete machine equipment emulsified bitumen equipment.
If the gap of the black antistatic medical tweezers bitumen concrete micro-powder machine of emulsified bitumen equipment is enlarged after long-term use, then we can adjust it and continue to process it. Emulsified bitumen equipment is a relatively simple difficulty.

Fillers used in emulsion bitumen equipment are generally divided into two types: chemically active and non-chemically active. In the production of emulsion bitumen equipment, it can improve the stability of the slurry mixture, speed up or slow down the demulsification speed, and improve the strength of the sealing layer. When adding chemically active fillers, the reaction and compatibility of the fillers with mineral materials and modified emulsion bitumen should be fully considered.

Emulsified asphalt equipment is a special equipment for producing emulsified asphalt. The emulsified asphalt produced by emulsified asphalt equipment is used in many industries. I wonder how much you know about the emulsified asphalt produced by emulsified asphalt equipment. Let’s take a look at them one by one:
Slurry seal is a cold mix asphalt mixture with the advantages of aggregate and asphalt mixing. Under normal circumstances, similar graded slurry seal has a higher modulus than hot mix asphalt mixture, so it is often used to fill road rutting. The higher stability has a higher resistance to deformation. The mixture is usually composed of harder fine aggregate grading and wear-resistant aggregate with high sand equivalent, especially micro-seal and polymer-modified seal. This greatly increases the strength and integrity of the road surface. This makes the road surface have high wear resistance and excellent deformation resistance. Emulsified asphalt emulsion is also easy to use on a mobile slurry seal paver, where mixing and admixtures are used for chemical control to meet maintenance needs.

To ensure good operation of asphalt melting equipment and extend its service life, regular maintenance and repairs are required. The following are specific maintenance and repair steps:
First, various parts of the equipment, including heating elements, pipes, valves, etc., need to be inspected regularly to make sure they are not worn or damaged. If any problems are found, they should be repaired or replaced immediately.
