How to check the oil mark before using modified asphalt equipment

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

There are many types of bitumen emulsifiers, and there are many classification methods. For specific classifications, please refer to previous articles. The raw materials required for the production of emulsion bitumen are: bitumen, water and bitumen emulsifier. High-standard emulsion bitumen requires adding additives and adjusting acid. According to whether acid adjustment is needed in the emulsion bitumen production process, it can be divided into two categories: emulsion bitumen that requires acid adjustment and emulsion bitumen that does not require acid adjustment.

Asphalt spreader vehicle is an intelligent and automated high-tech product that specializes in spreading emulsified asphalt, diluted asphalt, hot asphalt, high-viscosity modified asphalt, etc.
Asphalt spreader is used for spreading the penetration oil, waterproof layer, and bonding layer of the bottom layer of the asphalt pavement of high-grade highways. The spreader consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, an ignition system, a control system, a pneumatic system, and an operating platform.
Asphalt spreader is cumbersome to operate. On the basis of absorbing various technologies of similar products at home and abroad, it increases the quality technology content of construction and the humanized design of outstanding improvement of construction conditions and construction environment. Its reasonable and reliable design ensures the uniformity of asphalt spreading, the computer control is stable and reliable, and the technical performance of the whole vehicle has reached an advanced level.

With the rapid development of our country’s social development and the continuous development of economic and information technology, modern highway construction is also developing rapidly, and the requirements for ground structural materials are becoming higher and higher, and Asphalt concrete bonding raw materials are inseparable from modified asphalt equipment. So besides these influencing factors, what other reasons does the company have that people don’t understand? Let’s analyze it together.
There are some asphalt concrete equipment on the market, because they have not solved the problem of asphalt clogging before grinding, there are not enough preparation equipment and grinding equipment, the structure is unscientific, and the entire grinding process cannot achieve a certain particle size, resulting in modification. The product productivity of asphalt equipment is low and the product quality is unstable. It requires continuous grinding for a long time, creating problems. This will not only greatly increase energy consumption, increase costs, make product quality unstable, and affect the speed of highway construction.

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.

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.

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.

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.

Bitumen decanter equipment can be placed in a complex system as an independent unit, replacing the existing heat source de-barreling method, or in parallel as a core component of a large set of equipment, or it can work independently to meet the requirements of small-scale construction operations.
The Sinoroader bitumen decanter device is mainly composed of a de-barreling box, a lifting mechanism, a hydraulic thruster and an electrical control system. The box is divided into two chambers, the upper chamber is a barreled bitumen melting chamber, and heating coils are evenly distributed around it. The heating pipe and the bitumen barrel mainly exchange heat in a radiation manner to achieve the purpose of bitumen de-barreling. Several guide rails are the tracks for the bitumen barrel to enter. The lower chamber is mainly to continue heating the bitumen removed from the barrel to make the temperature reach the suction pump temperature (100℃), and then the asphalt pump is pumped into the upper chamber. At the same time, an empty barrel is pushed out at the rear end outlet. There is also an oil tank on the platform at the entrance of the asphalt barrel to prevent the dripping bitumen from flowing out.
The inlet and outlet doors of the device adopt a spring automatic closing mechanism. The door can be automatically closed after the asphalt barrel is pushed in or out to reduce heat loss. A temperature gauge is installed at the asphalt outlet to observe the asphalt outlet temperature. The electrical control system can control the opening and closing of the hydraulic pump and the reversing of the electromagnetic reversing valve to realize the advance and retreat of the hydraulic cylinder. If the heating time is extended, a higher temperature can be obtained. The lifting mechanism adopts a cantilever structure. The bitumen barrel is lifted by an electric hoist, and then moved horizontally to place the bitumen barrel on the guide rail. A temperature gauge is installed at the outlet of the asphalt meltering equipment to observe its outlet temperature.

Friends who are ready to get started have a surprise today. The editor will give you a brief introduction on how to produce emulsified asphalt.

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.

Analysis of the necessity of emulsified bitumen equipment in modern road construction projects With the acceleration of the construction speed of transportation infrastructure, the construction standards are getting higher and higher, and higher requirements are also put forward for the use of emulsified bitumen in the closed layer of fly ash and the adhesive layer between the new and old ground.

Emulsified asphalt is made by hot melting asphalt, dispersing it in an aqueous solution containing an emulsifier in a fine particle state through mechanical action, forming an oil-in-water asphalt emulsion. In road construction and maintenance projects, emulsified asphalt can be used for road maintenance, bonding between road layers, bridge deck paving, permeable oil on cement-stabilized macadam foundation, slurry seal waterproof layer, etc. It has the advantages of cold construction, safety, environmental protection, resource conservation, energy conservation, extended construction season, and improved construction conditions. It plays a very important role in the construction and maintenance of municipal roads, especially in recent years, the improvement of the production level of emulsified asphalt has actively promoted the technological progress and promotion and application of emulsified asphalt. However, in the production and use of emulsified asphalt, undesirable phenomena such as crusting, flocculation, oil-water stratification, and agglomeration often occur, which brings unnecessary troubles to construction. To this end, the author conducted a large number of experimental studies from nine aspects, including emulsification equipment, emulsifier, base asphalt, pH value, temperature, storage temperature, mechanical action, freezing and melting, and long-term placement, and summarized the factors that affect the stability of emulsified asphalt. The analysis is as follows:

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.

1. When operating an asphalt spreading truck, first check whether the machinery, spreading devices, protective and fire prevention equipment are complete and effective.
2. It is strictly prohibited to use non-specified fuel as the fuel for the heating system. The fuel is not allowed to overflow outside the tank. Generally, the oil level should be 20-30cm lower than the upper end of the overflow pipe.

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.

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.
