Specific construction steps of slurry sealing layer

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.

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.

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.

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.

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!

What is the overall operation process of bitumen (composition: asphaltene and resin) drum melting equipment?
The bitumen (composition: asphaltene and resin) drum melting equipment produced by our company mainly uses barrel debarking and melting of large barrels of bitumen (definition: the transformation process of materials from solid to liquid), using high-temperature thermal oil as the material (playing a decision-making role substance), used in supporting facilities of high-temperature thermal oil heating equipment.

I. Visual Appearance Acceptance Specifications
The surface must exhibit a continuous and uniform coverage, with no air bubbles exceeding 3mm in diameter or any uncovered areas.
Joints should have smooth transitions, forming a complete interface with the existing pavement, with color difference controlled within ΔE≤5.
The fine-grained texture unique to micro-surfacing should be clearly visible, and aggregate distribution uniformity must reach over 90%.

There are certain standards for the composition and mix ratio of micro-surfacing, and a wide range of materials are used, including polymer-modified emulsified asphalt, various aggregates, cement, water, additives, etc. Raw material quality has a significant impact on microsurfacing performance, so understanding the performance of each component and the key factors that influence its performance is critical to ensuring the quality of your microsurfacing mix.

Working conditions of asphalt debarreling equipment:
(1) Outdoor temperature: 20°C (average temperature of day and night)
(2) Heat exchange oil: 320 ℃
(3) Loading time is not included (because the personnel equipped in each unit are different, so the loading time is also different)
(4) There is no fluctuation in oil temperature (optimal automatic burner)
(5) The working temperature of the oil furnace is 220-260 ℃
(6) The flow rate of the oil circulation pump is not less than 50m3/h traffic
(7) When the outdoor temperature is lower than 20℃, the output decreases. The lower the temperature, the lower the output, and the higher the temperature, the higher the output.
(8) The greater the deformation of the asphalt barrel, the greater the impact on the output

Fine-grained asphalt road is a type of road surface constructed using fine-grained asphalt mixtures.
I. Material Composition
Asphalt Binder: Typically, road petroleum asphalt or modified asphalt conforming to relevant standards is selected. For general urban roads and highways, No. 70 or No. 90 road petroleum asphalt is commonly used; in some special sections, such as heavy-duty traffic roads or roads in high-temperature areas, modified asphalt may be used to improve pavement performance.
The quality of the asphalt directly affects the pavement’s durability, aging resistance, and crack resistance. High-quality asphalt should have appropriate viscosity, softening point, and ductility, maintaining good performance under different climatic conditions.
Fine Aggregate: Generally, natural sand, manufactured sand, or stone chips are used. The particle shape, gradation, and mud content of the fine aggregate have a significant impact on the performance of the asphalt mixture.
The particle shape should be as close to cubic as possible to improve the stability and density of the mixture. The gradation should meet design requirements. A reasonable gradation allows fine aggregates to form a good interlocking structure in the mixture, improving pavement strength and durability. The mud content should be strictly controlled within the specified range; excessive mud content will reduce the adhesion between asphalt and aggregates, affecting pavement quality.
Coarse Aggregate: Commonly used coarse aggregates include crushed stone and crushed gravel. The strength, hardness, and abrasion resistance of coarse aggregates are key indicators and should meet certain technical requirements to ensure the pavement can withstand vehicle loads and wear during use.
Its particle size is generally above 4.75mm, playing a skeletal supporting role in the asphalt mixture. A reasonable coarse aggregate gradation can increase pavement stability and load-bearing capacity.

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.

I. What is a Synchronous Chip Seal Truck?
This engineering vehicle, resembling a Transformer, is actually a “grout sealer” for road construction. It can simultaneously complete two key processes while in motion: spraying emulsified asphalt and evenly spreading chipped aggregate. Compared to traditional step-by-step construction, efficiency is increased by approximately 40%, and the adhesion effect is more ideal. Currently, the mainstream models can be divided into two types based on chassis structure: self-propelled and towed.
II. Practical Comparison of Two Vehicle Types
Self-propelled: Self-powered, highly maneuverable, suitable for urban roads and small-scale projects; turning radius is typically within 8 meters.
Trailer-mounted: Requires a tractor unit, but has a larger loading capacity; the crushed stone bin can reach 15 cubic meters, designed specifically for large projects such as highways.
Hybrid: An emerging modular design that allows for quick replacement of asphalt tanks or crushed stone bins according to project needs.
III. The New Trend of Intelligentization
Modern vehicles are transforming into ‘thinking’ construction robots:
Laser ranging systems automatically adjust spray volume
BeiDou positioning achieves centimeter-level path tracking
Touchscreen control replaces traditional mechanical joysticks
Real-time cloud-based analysis of construction data
These upgrades reduce material waste per square meter by approximately 12%, while improving construction accuracy by 30%.

With the performance, the damaged part is restored in time to ensure the safety, comfort and smooth driving, saving transportation costs and time; Correct technical measures should be taken to improve the quality of the project, extend the service life of the road, and postpone the reconstruction time.

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 emulsifiers can be divided into synthetic emulsifiers, natural emulsifiers, inorganic powder emulsifiers, etc. according to their formation. Synthetic emulsifiers are currently the most widely used. Asphalt emulsifiers are a type of organically synthesized surfactant that can emulsify asphalt.
Emulsifiers are divided into ionic and non-ionic types according to whether the hydrophilic group of the emulsifier molecule is charged when the emulsifier is dissolved in water. Ionic emulsifiers are divided into cationic and anionic types due to the different charges of the hydrophilic group after ionization in water. In addition, there are zwitterionic types.
Cationic emulsifiers are divided into three types: fast cracking, medium cracking, and slow cracking according to the speed of demulsification. Slow cracking emulsifiers are divided into slow setting and fast setting according to the length of time the mixture solidifies. Slow cracking and slow setting types are mainly used as permeable oils. Slow cracking and fast setting are used for micro-surfacing, slurry sealing, cold regeneration, etc. Medium cracking and fast cracking types are used for adhesive layer oils, gravel sealing layers, and waterproof base oils.

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.

When using an asphalt pump, regular inspection and maintenance are necessary to ensure the equipment functions properly and improve work efficiency and quality.

Emulsified asphalt can be spread by mechanical spreading and manual spreading. Different spreading methods will have different effects on pavement performance, so it is very important to choose the right spreading method. At the same time, maintenance and management after spreading are equally important to ensure the safety and durability of the pavement.
Emulsified asphalt is a common pavement material that is widely used in road construction and maintenance. There are two main ways to spread emulsified asphalt: mechanical spreading and manual spreading. Mechanical spreading generally uses a special spreading vehicle that can quickly and evenly spread emulsified asphalt. Manual spreading is carried out by workers using tools such as brushes or rollers, which is suitable for pavement treatment in small areas or special areas.
Different spreading methods also have different effects on pavement performance. Mechanical spreading can quickly complete large-area treatment and spread evenly, which is conducive to ensuring the flatness and anti-skid properties of the pavement. Manual spreading can more finely treat special areas such as shoulders and intersections to improve the overall performance of the pavement.

This precise construction method can effectively improve the flatness and pressure resistance of the road surface, reduce the possibility of road damage and breakage, and extend the service life of the road.
Secondly, the use of fiber-reinforced synchronous sealing vehicles can improve the efficiency and quality of road construction and maintenance. Through the automated construction process, quality problems caused by human errors and irregular operations can be reduced, and the consistency and stability of construction can be improved. This not only saves manpower and time costs, but also improves the overall efficiency of road construction and maintenance.
In addition, the fiber-reinforced synchronous sealing vehicle can also reduce the impact of the construction site on the environment. The use of advanced spraying technology and material recovery devices can reduce the waste of gravel and materials, reduce the interference and pollution of construction to the surrounding environment, and conform to the concept of sustainable development.
In general, fiber-reinforced synchronous sealing vehicles are of great significance in road construction and maintenance. They not only improve the service life and quality of roads, but also improve construction efficiency and reduce the impact on the environment. With the continuous advancement of science and technology and the improvement of engineering technology, it is believed that fiber-reinforced synchronous sealing vehicles will play a more important role in future road construction and maintenance, and contribute more to the construction and maintenance of transportation infrastructure.
