Product Details

Product Introduction

Hot-melt road crack sealant is a high-performance hot-melt material specially used for road crack repair, waterproof sealing, and preventive maintenance. The product is made of high-quality modified asphalt, high-molecular polymers, and anti-aging materials, featuring excellent low-temperature flexibility, adhesion, waterproof performance, and anti-aging performance.

During construction, the material is heated and melted using specialized heating equipment, then injected into the cracks. After cooling, it forms a highly elastic sealing layer, effectively preventing rainwater, sediment, and debris from entering the pavement base, reducing further crack propagation, and extending the overall service life of the road.

The products are widely used in road maintenance projects such as highways, municipal roads, bridges, airport runways, industrial parks, and parking lots.


Temperature Rating

According to the climatic environment of different regions, the product offers multiple low-temperature grades:

-10℃ Type

Applicable to ordinary cold regions and mild climate environments.

-10℃ Type

Suitable for northern cold regions and winter low-temperature environments.

-10℃ Type

Suitable for road maintenance projects in Northeast, plateau, and extremely cold regions.


Product Features

Excellent Low-Temperature Flexibility

Maintains good elasticity in low-temperature environments, not prone to brittle cracking.

Strong Bonding

Excellent adhesion to substrates such as asphalt and cement, not easy to peel off.

High Elastic Anti-Crack

Able to adapt to road thermal expansion and contraction as well as changes in vehicle load.

Waterproof Seal

Effectively prevent rainwater infiltration and reduce base layer damage.

Strong aging resistance

Maintains stable performance even after prolonged exposure to sunlight, rain, and snow.

Wear-resistant and pressure-resistant

Suitable for areas with frequent vehicle traffic.

Hot Melt Installation

Good fluidity after heating, high construction efficiency.

Fast Traffic

After construction is completed and cooled down, traffic can be resumed.


Scope of Application

Highway crack repair Municipal road maintenance Asphalt pavement crack sealing Cement concrete pavement joint treatment Bridge expansion joint maintenance Parking lot crack repair Airport runway maintenance Industrial Park Road Maintenance


Construction Method

1. Crack Cleaning

Remove dust, debris, and loose particles from inside the cracks.

2. Slotting Treatment

Use slotting equipment to organize cracks as needed.

3. Heating material

Use specialized hot melt equipment to heat to the construction temperature.

4. Crack Filling Construction

Uniformly pour the melted crack sealant into the cracks.

5. Natural Cooling

Open traffic after the material cools and solidifies.


Product Advantages

Compared with common asphalt materials, hot-melt road crack sealant has stronger elastic recovery capability, better waterproof sealing effect, and longer service life, which can effectively reduce the problems of repeated cracking and rainwater erosion.

The product is suitable for road preventive maintenance projects, helping to reduce later maintenance costs and improve the overall service life of roads. It is a commonly used professional crack repair material in modern road maintenance engineering.
