The construction requirements of asphalt penetration layer are as follows: within 6 hours after the base layer is rolled, the penetration oil must be sprayed in time. The penetration oil uses emulsified asphalt PC-2, and its dosage can be determined by trial spraying according to the standard of 1.5 liters per square meter, and the penetration depth must not be less than 5mm. After spraying the penetration oil, the emulsified asphalt PC-1 lower seal layer needs to be paved, where the emulsified asphalt dosage is 1.0 liters per square meter, the aggregate particle size is 0.5-1cm, and the thickness should not be less than 0.6 cm. Before paving asphalt concrete, the tack oil must be sprayed on the upper and lower layers of the lower seal layer, as well as on the sides of curbs, rainwater outlets, inspection wells and other structures. The tack oil uses emulsified asphalt PC-3, and the dosage is 0.5 liters per square meter.

The thickness of slurry seal is usually between 1-3 cm, and the specific thickness selection depends on factors such as road conditions and usage requirements. Slurry seal is widely used in road maintenance and can effectively improve road performance and service life. Slurry seal is a commonly used road maintenance technology, and its thickness is usually between 1-3 cm. This seal material is mainly composed of emulsified asphalt, cement, filler, water and additives, which are mixed and stirred in a specific proportion. Slurry seal plays an important role in road maintenance. Below we will comprehensively analyze it from the aspects of thickness selection, construction technology and application.

When constructing fiber slurry seal in hot weather, special attention should be paid to the control of materials, construction technology and environmental conditions to ensure construction quality and durability. The following are key considerations: 1. Material selection and processing Asphalt emulsifier type: slow-cracking and fast-setting emulsified asphalt is preferred to avoid premature demulsification at high temperatures, which affects paving and molding. Fiber stability: Select high-temperature resistant fibers (such as polyester and lignin fibers) to prevent fiber deformation or degradation at high temperatures. Aggregate requirements: Aggregates must be clean and dry. Avoid using highly absorbent materials (such as porous basalt) at high temperatures to prevent rapid evaporation of moisture and cause the mixture to become brittle.

After the asphalt spreader has been used for a period of time, many stains will be generated around the equipment. If it is not cleaned for a long time, a thick layer will be formed, which is more difficult to clean. Although the cleaning methods are all known, we need to pay attention to some asphalt spreader issues when cleaning the construction.

Asphalt melting equipment follows the continuous development of urbanization. Whether in rural areas or in big cities, you can see a lot of construction sites, among which it is inevitable that asphalt melting equipment is set up nearby. Asphalt melting equipment manufacturers, whether large or small asphalt melting equipment or relatively large and small, although it is just a simple mechanical equipment, but to move or transport it, it is a small matter, and there are many places that require attention.

If the emulsified asphalt equipment is not maintained during use, it will lead to a short cycle and problems will often occur during use. Only by doing a good job of maintenance can the equipment operation efficiency be improved. For example, during maintenance, the following points must be grasped.

I wonder how much you know about the relevant applications of bagged asphalt melting equipment? In order to use the asphalt equipment more quickly, we need to understand the internal structure characteristics of the bagged asphalt melting equipment. Let's follow me to learn about it. I believe it will be helpful to you.

According to the production process, the emulsified modified asphalt equipment can be divided into three types: intermittent emulsified modified asphalt equipment operation, semi-continuous emulsified modified asphalt equipment operation, and continuous emulsified modified asphalt equipment operation. During the production of the emulsified modified asphalt equipment, demulsifier, acid, water, and latex modified materials are mixed in the soap mixing tank, and then pumped to the colloid mill with asphalt. After a tank of soap is used up, it is replenished with soap, and then the production of the next tank is completed.

In the process of comprehensively promoting the rural revitalization strategy, rural infrastructure construction has become a top priority, and rural road construction is a key link. A flat and durable rural road can not only improve the travel conditions of villagers, but also inject strong impetus into rural economic development. As a powerful equipment for road construction, emulsified asphalt spreaders are playing an indispensable role in rural road construction with their unique advantages, helping rural areas embark on a new journey of high-quality development.

Fiber-crushed stone synchronous sealing vehicle is a professional road construction machinery that can effectively improve road quality, extend road service life, and ensure driving safety and travel comfort. In modern transportation construction, fiber-crushed stone synchronous sealing vehicle has important application value.
