What Is Asphalt Sealant? What Are The Characteristics?

Road cracks are one of the common diseases on highway surfaces. In order to improve the driving performance of the road surface, it is necessary to pay more attention to road cracks and take timely measures to repair them. At present, the commonly used treatment method for road cracks is to inject hot melt sealant into the cracks to control their development. Fanuode road sealant has high viscosity and good elasticity, which improves the service life of highways.

In terms of material selection, there are generally traditional asphalt filing and road sealant filing. Nowadays, replacing the traditional asphalt grouting process with sealant filing technology to treat asphalt pavement cracks is a major improvement in current highway maintenance technology.

High quality hot repair asphalt/cement crack sealant, composed of synthetic rubber or recycled rubber, or a mixture of both, with the addition of asphalt binder and other modified materials. At room temperature, it appears as a solid block, and after heating and melting, it becomes a black colloid with super strong extensibility and adhesion, which can efficiently seal road cracks and joints and maintain the sealing effect for a long time; After completing the construction, it takes about 15 minutes to cool down and restore traffic.

It is suitable for sealing and repairing cracks and joints in asphalt/concrete highways, expressways, runways, residential roads, etc.

Requirements for pavement grouting:

1.When slotting and grouting, slots should be made along the cracks, and the depth and width of the slots should be appropriate or meet the design requirements.

2.The dust and debris in the cracks should be cleaned thoroughly.

3.When using heated sealant, the cracks and the surrounding road surface should be heated; When using room temperature sealant, only dry road surface requirements can be met.

4. The sealant should be poured into the crack or slot.

5. If the spilled material is ironed out, necessary anti sticking wheel treatment should be carried out.

Fanuode pavement repair material - PINUS LONGAEVA sealant is a specially treated polymer material with strong adhesion, superior weather resistance, and aging resistance. This product feature has enabled PINUS LONGAEVA sealant to achieve excellent results in repairing cracks in asphalt pavement networks.

PINUS LONGAEVA sealant repair technology uses high-pressure injection material, which can fully fill the gaps and achieve the goal of perfect repair of road network cracks. At the same time, PINUS LONGAEVA sealant also has extremely high elasticity, which can maintain good performance even under the influence of traffic loads and environmental changes, extending the service life of asphalt pavement.

For the past decade, the "Fanuode" has been committed to the pursuit of quality. The road maintenance machinery independently developed and manufactured has accumulated high product reputation and market reputation. The products all use Omron control systems and components from brands such as Siemens, Delta, XYK, Yanmar, Honda, etc., making operation and construction convenient and efficient, effectively reducing equipment wear and tear, and making the performance of road maintenance equipment more stable.
