Hot‑pour Asphalt Crack Sealant For Highway Pavement Crack Repair

Product Introduction

This product is a hot-poured bituminous pavement joint sealing material, refined from base bitumen blended with polymer elastic modifiers, anti-aging additives and tackifying components. During construction, it is melted at high temperature and poured into various pavement cracks and expansion joints. After cooling, it forms a highly elastic sealing layer that closely adheres to concrete and asphalt substrates. It effectively seals gaps to prevent rainwater and sediment from infiltrating the road base, fundamentally eliminating pavement damages such as cracking, potholes and subgrade settlement. It is widely applied to maintenance projects of transportation infrastructure including highways, municipal roads, bridges and factory floors.

Product Advantages

1. Excellent high and low temperature resistance, stable performance all year round

Adaptable to various national climatic conditions. It will not soften, flow or stick to tires under high temperature and strong sunlight in summer. It remains flexible without cracking or embrittlement in severe cold weather, resisting frost heave deformation at sub-zero temperatures. It maintains long-term sealing integrity and avoids repeated repairs.

2. High flexibility and deformation follow-up, preventing secondary cracking

Featuring excellent tensile and resilience properties, the sealant stretches and contracts synchronously with pavement thermal expansion and contraction, vehicle compression deformation, and slight subgrade settlement. It perfectly adapts to dynamic width changes of cracks, effectively buffers pavement stress, and fundamentally reduces secondary cracking, peeling and damage of cracks.

3. Super adhesion and outstanding waterproof sealing performance

It closely bonds and firmly interlocks with asphalt and cement concrete pavement. After curing, it does not fall off, peel or crush, and can withstand repeated rolling of heavy-duty vehicles. It fully seals gaps and completely blocks the infiltration of rainwater, snow and sediment into the subgrade, effectively preventing subgrade erosion, hollowing, settlement and mud boiling, and greatly extending the service life of roads.

4. Efficient construction and fast traffic opening

The construction process is simple and highly adaptable. The hot-melt type features good fluidity and smooth pouring, while the normal-temperature type requires no heating and is ready for immediate use. The construction is slightly affected by low temperature and light rain. It cures rapidly after construction and allows traffic opening in a short time, greatly shortening the construction period, reducing road enclosure time and alleviating traffic congestion.

5. Wear and pressure resistance, suitable for heavy-load roads

The cured product has a dense and solid structure with excellent puncture resistance, wear resistance and compression resistance. It can withstand long-term high-frequency rolling of heavy vehicles without damage or collapse, making it suitable for high-intensity use scenarios such as expressways and heavy-load road sections.

The product is non-toxic, odorless and environmentally friendly with no harmful volatile substances, ensuring safe and pollution-free construction. A single construction delivers a long service life, greatly reducing the cost of repeated road maintenance and rework, with far better comprehensive economic benefits than traditional repair materials.

It is highly compatible with base cracks of different widths, repairing vertical, horizontal and reticulated cracks. It has lenient requirements on the flatness and dryness of the base layer with a high construction tolerance, applicable to various pavement
