How to add bitumen emulsifier

Emulsified asphalt equipment hot-melts basic colored asphalt and mechanically distributes tiny colored asphalt particles in an aqueous solution containing emulsifier to form a liquid colored asphalt material. The cement emulsified asphalt equipment mortar used in slab ballastless track construction uses cationic emulsified asphalt equipment. The purpose is to adjust the elasticity, toughness and durability of the cement emulsified asphalt equipment mortar. Polymers are often used to modify the asphalt.

As a black road construction machinery, the synchronous chip sealer is the main equipment for highways, urban roads, airports, and port terminal facilities. Do you know what kind of synchronous chip sealer? What products do you have to choose from?
Asphalt dispensers are classified according to the purpose, operation mode, and drive mode of the asphalt pump. According to the purpose, asphalt dispensers can be divided into two types: road use and road construction use. The asphalt tank capacity of the asphalt dispenser used for road construction generally does not exceed 400L, while the asphalt tank capacity of the asphalt dispenser used for road construction is 3000-20000L.

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.

Energy conservation and environmental protection are also excellent ways for Chinese companies to break down foreign trade barriers. By the end of 2011, the annual fuel consumption of my country’s construction machinery products exceeded the total annual output value of construction machinery. Currently, market entry barriers in countries like the United States and Japan are rising, and emission standards are a primary concern among these trade barriers. Industry experts believe that energy conservation and emission reduction in the construction machinery industry are challenging, often hindered by technical bottlenecks. Therefore, increasing research and development efforts is an effective way to address this situation. Energy conservation and environmental protection are the inevitable trends in the development of China’s construction machinery industry.
Whether it is to reduce environmental burdens or break down foreign trade barriers, energy conservation and environmental protection will become the mainstream trend in the development of construction machinery. The future development of China’s construction machinery industry will place greater emphasis on transformation and upgrading, and energy conservation and environmental protection will be a key focus in its implementation strategies. Currently, construction machinery manufacturers are incorporating more energy-saving and environmental protection elements into their new products. At the just-concluded biennial Shanghai Bauma Show, renowned international construction machinery companies like Komatsu, Hyundai, and Volvo Construction Equipment, as well as Chinese construction machinery giants like Sany, XCMG, Zoomlion, and Liugong, showcased their latest equipment, all boasting enhanced energy-saving and environmental performance. This demonstrates that the future of construction machinery will inevitably be dominated by energy conservation and environmental protection. Construction machinery companies must prioritize their own efforts to achieve higher product efficiency and superior energy-saving and consumption-reduction performance.

Asphalt distributors can spray, lay, and compact asphalt, improving construction efficiency and ensuring project quality.
Asphalt distributors play a crucial role in modern road construction. They not only efficiently apply asphalt but also assist with laying and compacting, providing strong technical support for road construction. So, how do asphalt distributors accomplish these three key tasks? Let’s take a closer look.
1. Asphalt Spraying: Uniform and Efficient, Improving Project Quality
One of the primary functions of an asphalt distributor is to spray asphalt. It evenly applies asphalt to the road surface, ensuring the thickness and uniformity of the asphalt layer meet design requirements. During the spraying process, the asphalt distributor can adjust the spraying speed and volume according to actual needs to meet varying road conditions and construction requirements. Furthermore, asphalt distributors are equipped with advanced control systems that precisely control the amount of asphalt sprayed, avoiding waste and pollution.
2. Asphalt Paving: Smooth and Dense Paving, Improving Road Performance
After spraying asphalt, asphalt distributors can also perform asphalt paving. It quickly spreads the asphalt sprayed on the road surface and, through vibration or rolling, makes the asphalt layer denser and smoother. This step is crucial for improving the road’s smoothness, density, and skid resistance. The asphalt spreader’s laying process ensures that the asphalt layer is tightly bonded to the base layer, forming a complete pavement structure.

1. Emulsion Batching System: Automatic temperature control, manual weighing and batching, equipped with a timed agitator and a residual material vent.
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.

Warm mix agents enable cooler application by reducing asphalt viscosity, reducing asphalt mixture production temperatures by 20-30°C (NATC data). Key types include organic viscosity reducers (such as Fischer-Tropsch wax, at a 0.3%-0.5% addition rate), foaming agents (at a 2%-3% addition rate), and chemical surfactants (such as Evotherm, at a 0.5%-0.8% addition rate). Selection should consider climatic conditions and cost budgets. Strict temperature control is required during application: mixing temperature 120-140°C, paving temperature ≥ 110°C, and initial compaction temperature ≥ 100°C (JTG F40-2004 specification). Mixture production should ensure a dry mix time of 5 seconds and a wet mix time of 30 seconds. Transport should be covered with a blanket, and transport distances should be ≤ 1 hour. The paving speed is 2-4 m/min, the loose paving coefficient is 1.15-1.20, and compaction is performed using a double-drum roller (two static passes and four vibratory passes). The final compaction temperature is ≥80°C. Warm-mix technology can reduce fuel consumption by 15%-20% and CO? emissions by 30%. A 10-kilometer, two-way, four-lane project is expected to save approximately 50 tons of diesel and reduce costs by 8%-12%.

In addition to being used according to regulations, modified bitumen equipment should also be maintained regularly in order to effectively extend the service life of modified bitumen equipment. The delivery pump of modified bitumen equipment, as well as its motor and reducer, need to be maintained in accordance with the specifications of the instructions. If the modified bitumen equipment is parked for a long time, the liquid in the tank and pipeline needs to be drained, and each moving component also needs to be filled with grease. The dust in the control box of the modified bitumen equipment needs to be cleaned once every six months. A dust blower can be used to remove dust to prevent dust from entering the machine and damaging parts. The micro powder machine needs to add unsalted butter once for every 100 tons of emulsified bitumen produced.

Gravel Synchronized seal Trucks are essential road construction equipment. Regular maintenance and care are essential to ensure proper operation and extend their service life. This article provides a maintenance and care guide for Gravel Synchronized seal Trucks to help users manage their equipment correctly on a daily basis.

Everyone has a side of themselves that they don’t want others to know. As a preventive road maintenance technology, slurry sealing has some shortcomings. do you think so?
Slurry seal is a kind of road protection that uses special equipment to mix emulsified asphalt, water, additives, aggregates, fillers and other ingredients in a certain proportion, and then mixes the slurry mixture onto the original road surface to form a thin layer. Maintenance technology. These are all well known. The editor will not go into details on this.

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.

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

Preventive pavement maintenance is a periodic mandatory maintenance measure, which is taken to restore the pavement surface service function when the pavement structure strength is sufficient and only the surface function is attenuated. New preventive maintenance technologies such as super-viscous fiber-added low-noise micro-surfacing and synchronous gravel seal have been widely used on the main lines of national highways, and the construction effect has been widely praised by customers.
Super-viscous fiber-added low-noise micro-surfacing starts with the gradation of micro-surfacing and the main material modified emulsified asphalt. By reducing the structural depth of the micro-surfacing and changing the distribution state of the coarse and fine materials on the surface of the micro-surfacing, the driving noise is reduced, while ensuring its anti-skid performance, effectively improving its adhesion, waterproofness, durability and crack resistance, and can solve the defects of easy detachment, excessive noise and reflective cracks of ordinary micro-surfacing.

Asphalt is widely used in road construction, primarily for paving. Its advantages include the following:
Good adhesion: It bonds firmly with aggregate, tightly binding aggregate particles together to form a stable pavement structure that effectively resists damage from vehicle loads and natural factors.
Good waterproofing: Asphalt is impermeable, preventing rainwater from penetrating the pavement structure, protecting the roadbed and base layer from water erosion, and extending the service life of the road.
High smoothness: The paved road surface has good smoothness, providing a smooth driving surface for vehicles, reducing bumps and vibrations during driving, and improving driving comfort.
-Excellent skid resistance: Through the appropriate selection of aggregates and mix design, asphalt pavements can achieve excellent skid resistance, ensuring sufficient friction for vehicles in both wet and dry conditions, ensuring safe driving.
Easy to repair: Local damage is easy to repair, and can be repaired using hot or cold patching methods. The repaired pavement adheres well to the original surface and can be quickly restored to service. Convenient Construction: Asphalt pavement construction is relatively simple and can be quickly paved using mechanical equipment such as pavers. Traffic can be reopened relatively quickly after construction, minimizing impact on traffic.
Good Noise Reduction: Compared to cement concrete pavement, asphalt pavement effectively absorbs vehicle noise, reducing traffic noise pollution and improving the surrounding environment.

Emulsified asphalt (ingredients: asphaltene and resin) heating tank is a new type of equipment for heating emulsified asphalt. Its appearance replaces the traditional thermal oil heating equipment, which brings great convenience to our users and improves work efficiency. Then let’s take a detailed look at how it is better than the traditional thermal oil heating equipment.
Emulsified asphalt (ingredients: asphaltene and resin) heating tank is another new type of emulsified asphalt heating storage equipment developed by technically separating the characteristics of traditional thermal oil heating emulsified asphalt tanks and internal heat part (part) rapid emulsified asphalt heating tanks.

There are many types of emulsified bitumen, and PC-2 is one of them, which is a spray-type emulsified bitumen. It is used for spraying oil through the base layer of granular materials and health care spraying on semi-rigid base layers. There is also the PA-2 type, which has the same purpose as the PC-2 type. The difference is that the PC-2 type is a cation, while the PA-2 type is an anion.

Asphalt mixture is a kind of composite material, mainly composed of asphalt, coarse aggregate, fine aggregate, mineral powder, some also added polymer and wood cellulose; By these different quality and quantity of materials mixed to form different structures, and have different mechanical properties

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.

Classification analysis of emulsion bitumen equipment is used to heat-melt bitumen. According to the actual cutting effect of mechanical equipment, it is loosened into a solution with demulsifier in the form of tiny droplets to form oil-in-water asphalt. Industrial equipment for lotions. Emulsion bitumen equipment can be divided into three types: portable, transportable and mobile according to the equipment, layout and maneuverability of the equipment.

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:

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

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.

The hydraulic bitumen decanter equipment produced by our company uses thermal oil as the heat carrier and has its own burner for heating. The thermal oil heats, melts, debarks and dehydrates the asphalt through the heating coil. This device can ensure that the asphalt does not age, and has the advantages of high thermal efficiency, fast barrel loading/unloading speed, improved labor intensity, and reduced environmental pollution.
