The pavement asphalt grouting machine is a specialized equipment used to repair road cracks and is widely used in road maintenance and repair. It fills road cracks with high energy efficiency and precise working methods, preventing moisture and debris from entering, thereby extending the service life of the road and improving its safety and durability.

The principle of using the pavement asphalt grouting machine:

The working principle of the pavement asphalt grouting machine is based on the fluidity of high-temperature asphalt and precise control of the equipment. The operation process generally includes the following steps:

1. Crack pre-treatment: Before using the asphalt grouting machine, it is necessary to first clean the debris, dust, and loose materials in the cracks to ensure the grouting effect. Usually, cleaning is carried out through high-pressure airflow or mechanical cleaning equipment.

2. Heating asphalt: The asphalt grouting machine is equipped with a heating device that can heat the asphalt to the flow temperature, ensuring its good fluidity and adhesion. The commonly used heating methods are gas heating and electric heating.

3. Crack filling operation: When the asphalt reaches the ideal temperature, the equipment injects the asphalt into the crack through the control system. Grouting machines are usually equipped with nozzles or injection pipes, which can be adjusted according to the width and depth of cracks to ensure uniform filling of asphalt.

4. Cooling and solidification: After the grouting is completed, the asphalt will gradually cool and solidify in the air, forming a strong sealing layer that effectively prevents moisture from penetrating and avoids further crack propagation.

The advantage of pavement asphalt grouting machine lies in its high energy efficiency and fast operation mode, which can quickly fill cracks, avoid further deterioration of road damage, and reduce labor costs and construction time.

Market price of pavement asphalt grouting machine:

The price of pavement asphalt grouting machine varies depending on the brand, model, functional configuration, and manufacturer. Generally speaking, the price range of asphalt grouting machines on the market is as follows:

1. Small handheld asphalt grouting machine: This equipment is suitable for repairing small cracks and is suitable for daily maintenance in urban roads, rural paths, and other places. The price is generally around 20000 to 50000 RMB.

2. Medium sized vehicle mounted asphalt grouting machine: This type of equipment is suitable for large-scale road maintenance and can efficiently treat longer and wider cracks. The price is generally between 50000 and 120000 RMB.

3. Large scale fully automatic asphalt grouting machine: This equipment is suitable for large-scale road construction and maintenance projects, and can quickly and extensively repair cracks. The price is usually above 120000 yuan, and may even reach 300000 yuan, depending on the degree of automation and other advanced configurations of the equipment.

In addition to the price of the equipment itself, when purchasing an asphalt grouting machine, it is also necessary to consider the maintenance cost of the equipment, the price of consumables (such as asphalt), and transportation and installation costs.

As an important tool in the field of road maintenance, the pavement asphalt grouting machine plays an irreplaceable role in repairing various road cracks due to its high energy efficiency, precise operating principle, and selection of different models. From small handheld devices to large vehicle mounted equipment, different types of asphalt grouting machines meet the needs of projects of different scales. According to different needs and budgets, users can choose the appropriate asphalt grouting machine to ensure the high energy efficiency and durability of road maintenance operations.
