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.

Asphalt spreading truck is a kind of black ground construction machinery. It is an important equipment in the logistics construction of roads, municipal roads, airports and ports. This equipment is mainly used to spray different types of asphalt on the ground to meet the construction requirements of different levels of ground oil permeable layer, sticky layer, left and right permeable layer, fog permeable layer, etc.

The viscosity of the drum bitumen decanter equipment decreases as the temperature increases during the production process. Its output viscosity is about twice as high as every 12°C increase. During production, the base bitumen decanter equipment must first be heated to a liquid state and then emulsified. In order to better integrate the emulsification ability of colloid milling, the viscosity of base bitumen decanter is generally controlled to be about 200 cst. The lower the temperature, the higher the viscosity, which increases the pressure on the bitumen decanter pump and colloid milling, making emulsification impossible: However, on the other hand, in order to prevent the bitumen decanter equipment from weaning when the moisture of the finished product evaporates, it is impossible to heat the base asphalt barrel removal temperature too high, and generally use a colloid grinding inlet and outlet system. The finished product temperature should be below 85°C.

When performing bitumen melting, specialized equipment is required. These equipment usually include bitumen melting furnaces, asphalt mixers, asphalt conveying equipment, etc. Among them, the bitumen melting furnace is one of the most advanced equipments, which can heat solid bitumen to liquid state. In addition, asphalt mixers can mix liquid asphalt with stone to make asphalt concrete. , Asphalt conveying equipment can transport asphalt concrete to the construction site. The selection and use of these equipment are of great significance to ensure the quality of bitumen melting and construction efficiency.

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 equipments can greatly improve construction efficiency, reduce human resources and time costs, and ensure pavement quality at the same time.
First of all, reliable asphalt melter equipment can shorten heating time and work efficiency and avoid wasting energy. Secondly, the equipment is easy to operate and can reduce the incidence of on-site safety accidents. In addition, this equipment has an automatic control and monitoring system that can adjust the working status and parameters at any time to meet different construction needs and environmental conditions.

Asphalt used to pave roads. It can be obtained by regular vacuum distillation of crude oil with appropriate properties, and can also be obtained by shallow oxidation of vacuum residue or propane deasphalting process. It can also be prepared by mixing asphalt of different duction and injection degree

Due to the incorporation of a certain proportion of water into the slurry sealing mixture, it is easy to evaporate in the air. After the water is evaporated, it will become dry and hardened. Therefore, after the slurry is formed, it not only looks very similar to fine-grained asphalt concrete, but does not affect the visual appearance of the road. It also has the same technical properties as fine-grained concrete in terms of wear resistance, anti-skid, waterproofing, and smoothness. Slurry seal technology is used in highway pavement maintenance because of its simple construction technology, short construction period, low cost, high quality, wide application, strong adaptability, etc. It is an asphalt with both economy and high efficiency. Pavement maintenance technology is worthy of application and promotion.

Synchronous gravel sealing technology refers to the use of special synchronous gravel sealing truck equipment to lay and roll prepared gravel, asphalt and other materials to build a single layer of asphalt gravel wearing layer, which is important for highway pavement. protection of. From the perspective of characteristics, it is simple and easy to implement. It has obvious effects on the prevention of highway diseases, problem solving, later maintenance, and improvement of grade protection. It can also well extend the service life of 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.

Working conditions of asphalt debarreling equipment:
(1) Outdoor temperature: 20°C (average temperature of day and night)
(2) Heat exchange oil: 320 ℃

Do you know what its six technical features are? If you don’t know, just follow the editor of Sinoroader and take a look.

Asphalt melting equipment is an important road construction tool used to heat asphalt to the appropriate temperature for construction. It can provide reliable solutions and make road construction more convenient. The working principle of this equipment is to heat the asphalt to the appropriate temperature through a heater, and then transport the hot asphalt to the construction site through a conveying system.

Whether it is the application of modified asphalt equipment or the application of other equipment, if you want to extend its service life, you need to do daily maintenance work. In order to better help everyone, we have modified asphalt The maintenance methods that can be adopted when using the equipment are introduced as follows:

Emulsified asphalt equipment is an indispensable equipment in road construction and one of the basic equipment for waterproof coatings. What are the components of emulsified asphalt equipment? Today, we will explain the various parts of emulsified asphalt equipment in detail.
Required parts
Asphalt pump: a device for supplying asphalt to the colloid mill.
Emulsion pump: a device for supplying emulsion to the colloid mill.
Colloid mill: a device for mixing, homogenizing and emulsifying asphalt and emulsion.
Control system: a device for controlling the flow of asphalt and emulsion, and the start and stop of various pumps.
Emulsion blending: a device for mixing water, emulsifiers and other additives.
Water heating part: a device for heating water.

The modified asphalt equipment estimates the quality and uniformity of various raw materials from the material pile and conveyor at any time. The modified asphalt equipment checks the soil and oversized gravel, and checks whether there is any leakage in the cold hopper. Estimate whether the mixed material is mixed evenly, whether there is white material, whether the oil-stone ratio is reasonable, and check the concrete segregation of the asphalt mixture and the mixed material.
The modified asphalt equipment checks the control parameters of various basic parameters of the mixing device in the control room, the display values ??of the control screen, and the modified asphalt equipment checks whether the data statistics and display values ??of the computer and printout are consistent. Test the raw material heating temperature and the mixed material entry temperature of the modified asphalt equipment.

The slurry sealer is a special equipment for road maintenance that we see in our lives. The slurry sealer is mainly used to deal with the decrease in surface wear resistance, cracks, etc. of the road, to improve the waterproofness and skid resistance of the road surface, thereby greatly improving the driving comfort and flatness inside, so as to achieve a new effect for the road surface. So what is the operation process of the slurry sealer?
Before starting the slurry sealer, you should be prepared to test the quality of the slurry sealer materials before construction. One of the most important points is to certify and inspect whether the content of emulsified asphalt can meet the requirements of the specification, and the mixture should also meet the requirements. After confirming the measurement standards, check that the road surface to be constructed should be dry, free of debris, water, flat, etc.

Emulsified asphalt is an emulsion that disperses asphalt into the water phase to form a liquid at room temperature. This determines that emulsified asphalt has many technical and economic advantages over hot asphalt and diluted asphalt. We know that modified asphalt equipment is a road engineering machinery. In order to better promote users’ understanding of it, today the editor will introduce its characteristics to you so that users can better understand that modified asphalt equipment is used for modified asphalt. It consists of a main machine, a modifier feeding system, a finished product tank, a heat transfer oil reheating furnace and a microcomputer control system. The main machine is equipped with a mixing tank, a dilution tank, a colloid mill and an electronic weighing device. The entire production process is controlled by a computer automatic program. In addition, it can be learned that the product has the advantages of reliable quality, stable performance, accurate measurement, and convenient operation. It is an indispensable new equipment in highway construction. The advantages of asphalt equipment are prominently reflected in its two-way modification effect, that is, while greatly increasing the softening point of asphalt, it also significantly enhances the low-temperature ductility, improves the temperature sensitivity, and has a particularly large elasticity and recovery rate. The modified asphalt equipment has a long service life and a safe and reliable production process. The rotor and stator are specially heat treated, and the service life of the equipment is more than 15,000 hours.

Modified asphalt equipment is a widely used asphalt equipment. Now its ultra-high performance has been widely praised by users. However, we must first ensure the safe use of modified asphalt equipment in order to fully demonstrate its performance. So how much do you know about the safe use and operation of modified asphalt equipment? Today, Gaoyuan Road Construction 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 suspended 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, you should stop and check.
5. If the machine is stopped for more than one hour after the asphalt mixing is completed, clean the mixing barrel, pour in clean water, and clean the mortar. Then drain the water. Remember that there should be no water accumulation in the barrel to prevent the formula from changing and even rusting of the pages and other links.

The advantages of Sinoroader bitumen decanter equipment over similar domestic equipment are reflected in the following points:
1. The equipment produces 8-10t/hour, with an automatic telescopic sealed container structure. It uses an electric hoist to lift the asphalt barrel at the inlet guide tube. Start to control the hydraulic cart forward button, which will promote the barrel push (push and slide into the barrel). It is a 1300mm hydraulic cylinder with a 7.5-ton top thrust. The device has a beautiful appearance, reasonable layout, compactness, stable performance, and is suitable for production under various industrial and mining conditions.
2. Fast barrel removal: According to the principle of layered heating, it adopts four-layer thermal oil heating technology, a single inlet and outlet, and high thermal efficiency of heating; at the same time, it uses the waste heat of combustion gas for two heatings and efficient use of energy; the barrel body uses high-quality rock wool insulation material.
3. Good environmental protection: closed structure, no pollution.
4. No barrel hanging: The upper part of the asphalt barrel is hot, and each is directly affected by the thermal oil heating pipe. The barrel wall directly receives the heat dissipation of the heating coil, and the barrel is clean and fast, which will not cause waste of asphalt barrel hanging.
5. Strong adaptability: Suitable for imported and domestic barrels, and the deformation of asphalt barrels will not affect production.
6. Good dehydration: Use a large-displacement asphalt pump for internal circulation, stirring, water vapor overflows, and is naturally discharged from the exhaust port. After dehydration, asphalt can be directly used to produce asphalt mixture or used as matrix asphalt.
7. Automatic slag removal: This set of equipment has an automatic slag removal function. The filter device sets the asphalt circulation pipeline through the filter, which can automatically remove the barreled asphalt slag.
8. Safe and reliable: The equipment adopts an automatic control system, an automatic ignition burner import, can automatically control the temperature according to the temperature, and is equipped with corresponding monitoring instruments.
9. Convenient relocation: The whole machine is assembled with large components, which is easy to move and quick to assemble.

The base layer of asphalt pavement is divided into semi-rigid and rigid. Since the base layer and the surface layer are materials of different properties, good bonding and continuity between the two are the key requirements for this type of pavement. In addition, when the asphalt surface layer seeps water, most of the water will be concentrated at the joint between the surface layer and the base layer, causing damage such as slurry, looseness, and potholes to the asphalt pavement. Therefore, adding a lower seal layer on top of a semi-rigid or rigid base layer will play a vital role in enhancing the strength, stability and waterproofing capabilities of the pavement structural layer. The more commonly used one is to use asphalt gravel synchronous sealing technology.
So let’s take a look at how the construction of the asphalt gravel synchronous sealing truck is carried out:

Emulsified modified asphalt equipment includes sewage treatment, water storage tank, water metering and verification temperature control system, asphalt storage tank, asphalt external temperature control system, hot water pump soap seasoning system, soap storage tank, soap mixing pump, soap external temperature control system and metering and verification system, filter, hot asphalt mixing pump and metering and verification system, pipeline black anti-static tweezers, emulsified asphalt cooling system and retrieval equipment, product tank and electrical control system.
The whole set of procedures is modularized, and customers can freely match and use according to their needs. The application of each part of the equipment is as follows: Sewage treatment system: Mechanically filter and adsorb the general drinking water to react with epoxy resin to convert the strong drinking water into pure softened water, reduce the water holding capacity, and improve the emulsion effect of asphalt or asphalt concrete.

In the cold winter, you need to pay attention to the following points when using asphalt melting equipment:
1. Protection from cold and warmth: The equipment needs to be operated indoors or in a place with shading facilities, and ensure that the temperature of the equipment and the surrounding environment is maintained within an appropriate range.
2. Check the equipment: Before use, the equipment should be checked, including whether the circuits, fluid circuits and other parts of the equipment are working normally, and whether there are any leaks of electricity or water in the equipment.
3. Pay attention to safety: During operation, you should wear protective equipment and avoid direct contact with hot asphalt. At the same time, it is necessary to avoid equipment overload operation and prevent equipment damage and safety accidents.
4. Control speed: Reasonably control the working speed of the equipment according to weather conditions and road conditions to avoid overheating of the equipment, causing asphalt to flow too quickly or burn.
5. Storage conditions: When not in use, place the device in a dry, ventilated place with moderate temperature, and ensure that any residue in the device is completely removed.

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.

The main filter material of stainless steel barrel removal adopts five-layer sintered mesh. Standard five-layer calcination is made by stacking and vacuum calcining five layers of stainless steel barrel removal wire mesh. The stainless steel barrel made of it has corrosion resistance, good water permeability, high compressive strength, easy cleaning and back-cleaning, high filtration precision, hygienic and clean filter material, and stainless steel barrel removal wire mesh does not fall off.
Double-layer metal sintered mesh is a new type of filtration system with high impact toughness and overall rigidity, which is made by stacking and vacuum calcining double-layer stainless steel barrel removal wire mesh products.

The viscosity of the bitimen melter equipment decreases as the temperature increases during the production process. Its output viscosity is about twice as high as every 12°C increase. During production, the base bitimen melter equipment must first be heated to a liquid state and then emulsified. In order to better integrate the emulsification ability of colloid milling, the viscosity of base bitimen melter is generally controlled to be about 200 cst. The lower the temperature, the higher the viscosity, which increases the pressure on the bitimen melter pump and colloid milling, making emulsification impossible: However, on the other hand, in order to prevent the asphalt debarrel equipment from weaning when the moisture of th

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.

What details should be paid attention to when adding materials to the emulsified bitumen equipment? Speaking of emulsified bitumen equipment, I don’t know how much you know? What should we pay attention to when adding materials?
The black anti-static tweezers grinding wheel of the emulsified bitumen equipment has no heating barrel. Before use, you must first add an appropriate amount of diesel, let the black anti-static tweezers circulate for 3 to 5 minutes to generate heat (the temperature after operation is about 80 to 100 degrees) Open the shut-off valve on the oil pipe and discharge the diesel in the machine. The temperature of the black anti-static tweezers grinding wheel is about 80 to 100 degrees before it can be loaded and put into production. If there is a heating collet, heat the grinding wheel before starting, and then load the materials for production.

Is the performance of Sinoroader’s fully automatic emulsified asphalt production equipment stable and unstable? To be honest, whether the performance of a product is stable or not can only be known through practice, right?
Chairman Mao, the great leader of China, once said, “Without practice, there is no right to speak.” Yes, people who have never used it naturally have no right to speak. Now the editor will talk about the fully automatic emulsified asphalt production equipment that I am using!

From three aspects, emulsion bitumen equipment has good economic performance:
First, energy saving. The kerosene or gasoline content in diluted asphalt can reach 50%, while the emulsion bitumen plant only contains 0-2%. This is a valuable saving behavior in the production and utilization of white fuel. By simply increasing the viscosity standard of asphalt by adding light oil solvent, asphalt can be poured and spread, and it is hoped that the light oil after use can evaporate into the atmosphere.
Second, versatility. There are many application methods for emulsion bitumen plants, and the appropriate method needs to be selected when applying it. The same emulsion can be used for large-scale sealing and can be used for small-scale pit repair work. Because they can be stored in tanks for a long time, they are very easy to use when applied in remote areas.
Third, it is easy to use. The professional spreading of emulsions requires professional equipment, such as spreaders. Small-area emulsion applications can be directly poured and spread by hand, such as small-area pit repair work, crack fillers, etc. Small quantities of cold mixes only require basic equipment.
