Asphalt spreader is an irreplaceable tool for highway maintenance. Asphalt spreader is an irreplaceable tool for highway maintenance. Highway maintenance is divided into four categories according to the nature of the project, scale, and technical complexity: minor repair, medium repair, major repair, and improvement. Specific classification:
(1) Minor repair and maintenance project: preventive maintenance and repair of slightly damaged parts of the highway and all its engineering facilities to keep them in good condition. It is usually planned and carried out daily by the maintenance team within the annual minor repair and maintenance quota funds on a monthly (ten-day) basis.
(2) Medium repair project: regular repair and reinforcement of general wear and tear and local damage of highway engineering facilities to restore them to their original state. It is usually planned and implemented by grassroots road maintenance agencies on an annual (seasonal) basis.
(3) Major repair project: periodic comprehensive repair of major damage to highway facilities to fully restore them to the original design standards, or local improvements and individual additions within the original technical level to gradually improve the highway’s traffic capacity. It is usually organized and implemented by grassroots road maintenance agencies or with the help of their superior agencies according to the approved annual project budget.
(4) Improvement projects are large projects that improve the technical level of roads and their engineering facilities in stages and sections due to their inability to meet traffic volume and load requirements, or significantly improve traffic capacity through improvements. It is usually organized and implemented or completed through bidding by regional road maintenance agencies or provincial road maintenance agencies according to the approved plan and design budget.

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.

The bitumen (composition: asphaltene and resin) drum melting machine adopts a self-heating integrated structure, which integrates the thermal oil boiler used in the old asphalt drum melting machine and the barrel removal equipment itself, reducing the volume of the entire equipment and significantly It reduces equipment investment (actual significance: it is the accumulation of future profits), saves the space occupied by the equipment and the logistics cost of switching sites. The combustion chamber is placed inside the equipment itself, which greatly reduces thermal damage and improves heat utilization.

Technical features of fiber sealing equipment:
1. Zero starting strong injection technology
With more than ten years of manufacturing history of asphalt spreading trucks and asphalt gravel synchronous sealing trucks, the zero-start strong spraying technology has been accumulated for many years. The combination of time-reliable hydraulic transmission components and Meitong’s control system can make the equipment instantly start from zero. Spraying starts in line, stable and reliable.
2. Duplex sealing structure
The sealing process of this equipment is a three-layer simultaneous and continuous construction process of one layer of asphalt + one layer of fiber + one layer of asphalt, forming a layer of interactive dense network winding structure, which fully meets the user’s construction requirements.

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.

What are the characteristics of bitumen emulsifiers? What are the differences between asphalt emulsifiers currently on the market? The manufacturer has compiled the following information to answer your questions and provide a more detailed understanding of the characteristics of bitumen emulsifier products.
1. The asphalt emulsifier produced by this manufacturer is a commonly used waterproofing material. During use, this bitumen emulsifier has undergone rigorous testing and has excellent self-adhesive properties. It is highly practical and widely used.
2. The asphalt emulsifier produced by this manufacturer is very convenient to apply. No special equipment is required; only a few people and a small vehicle are needed for normal application. The operation is simple, convenient, and fast, and no professional training is required for workers. Importantly, the asphalt emulsifier has good water resistance, good low-temperature performance, and strong adhesion. After application, it does not deform and is not easily deformed by rainwater.

I. The Dual Agent Role of Emulsifiers
Bitumen emulsifiers are like translators fluent in diplomacy, possessing a unique molecular structure: one end is oleophilic (receptive to bitumen), and the other is hydrophilic (receptive to water). When added to a mixture of bitumen and water, the oleophilic end tightly binds to the bitumen particles, while the hydrophilic end extends outward to combine with water, forming tiny bitumen spheres encased in water. This structure allows two otherwise incompatible substances to coexist peacefully.
II. Three Key Steps in the Emulsification Process
Mechanical Shearing: High-speed agitation breaks down the bitumen into tiny particles.
Charge Stabilization: The emulsifier coats the bitumen particles with a charged outer layer (usually negatively charged), causing them to repel each other and prevent aggregation.
pH Adjustment: Controlling the acidity or alkalinity to maintain the stability of the emulsion system, acting like a buffer for the mixture.
III. The Unsung Heroes of Road Construction
Emulsified bitumen can be applied at room temperature, saving over 30% more energy than hot bitumen. Once laid on the road surface, the emulsifier automatically “retires” after the water evaporates, allowing the bitumen particles to re-aggregate and form a continuous waterproof layer. This characteristic makes it particularly suitable for repairing potholes and working in rainy weather, making it a great helper for road maintenance.

Bitumen emulsion equipment is widely used in new technologies and new processes for preventive maintenance. Bitumen emulsion plant is an emulsion at room temperature formed by dispersing bitumen into the water phase. It is a new material that is made of natural materials. It is different from traditional Compared with hot bitumen, it saves more than 50% of energy, saves 10%-20% of bitumen, and causes less pollution.

The requirements for SBS asphalt emulsification equipment are very high. The micro powder machine must have a sufficiently large driving force and can bear the condensation type. Because the temperature requirements of the emulsion SBS asphalt process are relatively high, the emulsified asphalt should be passed through a heat exchanger before feeding to reduce the emulsified asphalt temperature to below 90°C to prevent the emulsified asphalt from breaking due to excessive temperature.
The application scope of SBS modified emulsified asphalt is very wide. According to the nature of the construction, it can be used in new construction, renovation, and reconstruction projects; according to the nature of the project, it can be used in overhaul, equipment overhaul, and maintenance projects. Among them, the actual application projects include micro-surfacing, cold regeneration, cold mixing and cold paving, adhesive layer, permeable oil, slurry seal, gravel permeable layer, fog permeable layer, road moisture-proofing, SBS membrane, ground seam filling, and all other projects that can use emulsified asphalt.

Stainless steel bitumen melters use bitumen concrete micro-powder machines. Its blade strength is high, the angular velocity of the moving disc is high, and the gap can be adjusted to 0.15mm. Stainless steel bitumen melters are suitable for the production and processing of various polymer bitumen concrete, such as SBS, PE, EVA, etc.
Stainless steel bitumen melters use independently developed special batching tanks, stainless steel bitumen melter force stirring devices, liquid level meter overflow prevention equipment, granular material dosage and equipment, liquid additive automatic addition equipment and other production key points. It ensures the full-position process guarantee for the stainless steel bitumen melter of the bitumen concrete production line. The stainless steel bitumen melter processing stainless steel bitumen melter rate is significantly increased, and the quality of stainless steel bitumen melters is greatly improved.

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.

1. There are generally three ways to heat emulsified bitumen plant: gas heating, heat transfer oil heating and open flame heating. The first is the gas heating method of emulsified bitumen plant. The gas heating method of emulsified bitumen plant requires the use of the fire pipe to transport the high-temperature smoke generated by high-temperature combustion through the fire pipe.
2. The heat transfer oil heating method of emulsified bitumen plant mainly uses heat transfer oil as a medium for heating. The heat transfer oil heating method has extremely high requirements for fuel. The fuel must be fully burned and the product must be transferred to the heat transfer oil after sufficient heat is transferred to the heat transfer oil pump for heating.
3. The open flame heating method of emulsified bitumen plant is the most direct and convenient heating method. Whether in terms of convenient transportation or coal consumption, the open flame heating method is the fastest choice, simple operation, sufficient fuel, structural design, and labor intensity are relatively reasonable.

In the application, the asphalt spreader has intelligent asphalt spreading rate and low investment, low power consumption, low cost, high thermal efficiency. The asphalt spreader can reach the temperature required for construction in a short time. It is easy to use and move. It can be operated by one person. A set of electric heaters is a bit expensive. In the production process of the asphalt spreader, water, as a production material, needs to be heated from room temperature to about 55°C. The evaporation heat of the asphalt spreader is transferred to the drainage. It is found that after the emulsified asphalt is produced for 5 tons, the asphalt spreader is accompanied by a significant increase in the temperature of the cooling circulating water. The production water uses cooling circulating water, and the water basically does not need to be heated. It can save 1/2 of the fuel simply from the energy.

In the field of road construction and maintenance, asphalt, as a core material, directly impacts project progress through efficient storage and transportation. The specialized equipment developed by asphalt drum unloading equipment companies is a key tool for the efficient conversion of asphalt from drums to a liquid state. This type of equipment rapidly transforms solid asphalt into a pumpable liquid state through precise temperature and pressure control, ensuring construction continuity while reducing material waste. This article will analyze the core advantages of this equipment from three dimensions: technical principles, application scenarios, and industry value.
Technical Principles: Synergistic Effect of Heat Exchange and Pressure Control
The core of asphalt drum unloading equipment lies in the precise coordination between the heat exchange system and the pressure control module. The equipment uses a built-in heat-conducting oil circulation system to uniformly heat the drummed asphalt to a melting temperature of 160-180℃, while simultaneously using a vacuum pump to remove air from the drum, creating a negative pressure environment. This dual action significantly shortens the asphalt melting time—traditional heating methods require 4-6 hours, while specialized equipment can complete the unloading process in just 1-2 hours. Furthermore, the equipment’s intelligent temperature control system monitors asphalt temperature in real time, preventing material degradation due to localized overheating and ensuring asphalt quality meets construction standards.

Asphalt spreader trucks are mainly used for pavement tack coat, primer coat, and seal coat construction in rural road construction. They feature precise control of the spread rate, strong continuous operation capability, and adaptability to complex terrain. The equipment adopts an electronic metering system and adjustable nozzle structure to achieve dynamic adjustment of asphalt flow, ensuring uniform spreading and improving pavement adhesion and durability. It is suitable for the construction and maintenance of low-grade roads such as county and township roads and village roads, especially in hilly and mountainous areas with poor traffic conditions, where its high mobility and convenient maintenance are significant advantages.
Application areas cover base treatment, preventive maintenance, and interface treatment before overlaying existing roads in rural roads. A typical technical solution is the “spread first, then pave” process, which enhances the adhesion between asphalt and the base layer by precisely controlling the spread rate (usually 0.6–1.2 L/m2), reducing water damage and early cracking. Some projects use intelligent control systems, combining GPS positioning and spread trajectory recording to achieve visualized management of the construction process.

2. Asphalt Batching System: Automatic temperature control, equipped with a timed agitator and a residual material vent.
3. Production System: Manually adjust the metering pump speed according to the set recipe to achieve ratio adjustment. The asphalt pipeline and pump use electric heating for automatic temperature control.
4. Sampling: Sampling is required during production for observation and related testing.
5. Finished Product System: Optional direct or cooled discharge is available. Finished product tanks are provided for pumping the finished product into the tanks.
6. Control System: The control system consists of intelligent temperature sensors, instruments, and conventional electrical appliances for easy inspection and maintenance.
7. Energy-Saving System: During the emulsified asphalt enters the finished product, a heat exchanger is used to dissipate excess heat to heat the water.

In road construction, waterproofing projects, and other fields, bitumen is a core material, and its storage and transportation directly impact project efficiency. Bitumen bagged melter equipment, as a key tool connecting packaging and use, is particularly important for its performance and adaptability. However, standardized equipment on the market often fails to meet diverse engineering needs. This is where the role of custom asphalt bagged melter equipment manufacturers becomes apparent – ​​solving the matching problem between equipment and application scenarios through customized design.
Core Functions and Challenges of Bitumen Bagged Melter Equipment The main task of asphalt bagged melter equipment is to efficiently and safely separate asphalt from its packaging bags and transport it to the heating or use stage. This process needs to overcome two major challenges: first, the viscous nature of asphalt makes it prone to residue or blockage within the equipment; second, the differences in packaging bag materials (such as paper and plastic) require specific handling to avoid contamination. Standardized equipment is usually designed for general scenarios, but in actual projects, there are numerous variables such as asphalt specifications, packaging forms, and site space, leading to frequent instances of equipment being unsuitable for specific environments. For example, a municipal engineering project experienced frequent equipment jams and delays due to the use of general-purpose equipment to process high-viscosity asphalt; another waterproofing material factory faced challenges because standardized equipment could not completely separate residues from the special material of its packaging bags, affecting product quality.

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.

Cold-mix colored asphalt, this new type of colored asphalt pavement, is truly a great product! It’s not only anti-skid, noise-reducing, and anti-fogging, but also particularly environmentally friendly, significantly improving road surface smoothness. In comparison, hot-mix asphalt seems more traditional. So, what are the differences between them? Let’s take a look!
Major Differences in Raw Materials
First, the binder in cold-mix colored asphalt is a modified cold-mix binder, which is liquid under normal conditions. Hot-mix colored asphalt oil, on the other hand, is solid and only becomes liquid after heating. This determines the differences in their production processes and usage methods.
Differences in Production Processes
Modified cold-mix binder is liquid and can be directly mixed with cold aggregates. Hot-mix asphalt oil and aggregates, however, need to be heated to a certain temperature before mixing. This heating process requires specialized equipment and time!
Major Differences in Construction Methods
The construction of cold-mix colored asphalt is not limited by temperature; it can be mixed, spread, and leveled on-site, and finally polished with a grinder. Hot-mix asphalt construction is limited by temperature and time, requiring compaction with pavers and rollers. This process demands a professional team!
Cure Time Differs Significantly
Cold-mix asphalt pavements typically require only 1-3 hours of curing time, after which they can be opened to traffic. Hot-mix asphalt pavements, however, require 24 hours of curing time, and traffic should be avoided for at least one day. Therefore, if you are in a hurry, cold-mix asphalt may be more suitable!
Service Life Differs Significantly
Cold-mix asphalt pavements generally last 1-3 years. Hot-mix colored asphalt, due to the addition of colorants, will fade after six months. Therefore, if you prioritize aesthetics and durability, hot-mix asphalt may be more suitable.
In summary, both cold-mix and hot-mix asphalt have their advantages and disadvantages; the choice depends on your specific needs and environmental conditions. Hopefully, this article has helped you better understand the differences between these two types of asphalt!

Open the clamping device of the drum decanter machine and place the jaws into the asphalt drum, ensuring full contact between the jaws and the drum wall.
Slowly move the jaws of the drum decanter machine upwards until they firmly grip the edge of the asphalt drum.
The above information is for reference only; for specific operating advice, consult a professional.

In the process of asphalt pavement repair, the core function of spraying emulsified asphalt is to enhance interfacial adhesion, seal voids, and provide waterproofing and seepage prevention. It also improves the integrity and durability of the repair layer and the original pavement. Specifically, its functions can be divided into the following:
Adhesive Layer Function: Strengthening interlayer bonding: After demulsification, the asphalt particles in the emulsified asphalt form a continuous asphalt film, tightly bonding the new asphalt mixture to the old asphalt layer and base course of the original pavement. This prevents the “two-layer” phenomenon and prevents the repair layer from shifting or detaching under vehicle loads.
Waterproofing and Seepage Prevention: Protecting the pavement structure: The sprayed emulsified asphalt fills the gaps between the original pavement and the repair layer, forming a waterproof barrier that prevents rainwater and snowmelt from seeping into the pavement structure. Moisture infiltration is a major cause of base course softening, subgrade settlement, and pavement cracking. The waterproofing effect of emulsified asphalt effectively extends the overall service life of the pavement.

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.

The main components of slurry seal mixture are aggregate, emulsified asphalt, and water. Mineral fillers and additives may also be added as needed. All materials have specific requirements and should be selected according to relevant specifications.
(1) Emulsified Asphalt
Emulsified asphalt is an important component of slurry seal mixture. It is used to coat the aggregate and ultimately exists as a binder in the slurry seal. Commonly used emulsified asphalt in road engineering includes cationic and anionic types, and according to the demulsification speed, it is further divided into fast-breaking (RS), medium-breaking (MS), and slow-breaking (SS). Emulsified asphalt used for slurry seal is generally slow-breaking, and currently, cationic asphalt is the dominant type.
(2) Aggregate
Aggregate is an important component of slurry seal mixture, forming the mineral skeleton. Stone materials that can generally be used for hot asphalt construction can also be used for slurry seal, such as limestone, granite, and basalt. Aggregates used for slurry seal must first meet specific gradation requirements, and secondly, they should be clean, hard, completely crushed, and have a uniform appearance. The clay content, i.e., sand equivalent, must also be controlled; the higher the clay content, the greater the harm. Based on the aggregate gradation type used in slurry seal pavement, it can be divided into three types: fine seal, medium seal, and coarse seal.

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.
