Based on the ambient temperature differences in the area of use, road sealants are classified into cold and low-temperature types, temperate types, and hot and high-temperature types. According to national standard classifications, road sealants can be divided into high-temperature, ordinary, low-temperature, cold, and severe cold types. Based on the heating method, road sealants can be divided into direct heating and indirect heating types. Road sealants melt quickly, have strong adhesion, and exhibit excellent deformation resistance and elastic recovery. Compared to other types of road sealants, Sanaisi Road Sealant has a lower viscosity and easily penetrates various cracks. At a high temperature of 180°C, the liquid road sealant penetrates and fuses with the asphalt pavement. Upon cooling, it develops a strong bond and, relying on its strong elasticity, deforms elastically as the crack expands and contracts, maintaining its sealing effect.
Asphalt road sealant is primarily composed of a composite material of modified asphalt and thermoplastic rubber. Its key performance characteristics are low viscosity at high temperatures and high elasticity at low temperatures. Replacing traditional asphalt crack caulking with sealant for treating asphalt pavement cracks represents a significant advancement in current highway maintenance technology. Traditional methods are limited by asphalt's low-temperature brittleness and high-temperature softening properties, resulting in cracks quickly reopening after repair. This problem increases the labor and material costs of pavement maintenance. However, sealant crack caulking overcomes these shortcomings in terms of material performance.

Used for longitudinal and transverse pavement cracks as part of preventive highway maintenance.
Proper crack sealing helps reduce water ingress and slows further deterioration around existing cracks.
The main application is sealing cracks in asphalt pavement before they develop into more serious structural deterioration.
The supplied material also identifies application on cement concrete pavements.
Project engineers should confirm joint dimensions and sealant grade according to the actual concrete pavement design.
Suitable for selected airfield pavement crack-sealing applications where the approved material specification meets project requirements.
Can be used for crack and joint sealing in bridge pavement maintenance applications according to the project specification.
It is a polymer-modified asphalt material designed to be heated into a fluid state and poured into pavement cracks to create a flexible, waterproof seal after cooling.
The supplied product information describes the material as primarily composed of:
Modified Asphalt + Thermoplastic Rubber
Yes.
This is a hot-pour road sealant, so it must be heated before application.
The supplied technical description states that the liquid sealant is applied at approximately:
180°C
The final recommended heating range should follow the confirmed formulation specification.
Yes. The supplied information states that different grades are available for:
Low-temperature
Cold
Severe-cold
applications.
