Construction Procedures

  • Preparatory Work

    Set up traffic safety warning signs; position slotting machines and crack filling equipment. Cut grooves to specified dimensions as per construction drawings. Preheat the crack filling machine, add sealant and agitate continuously, maintaining a working temperature of 170°C–200°C.

  • Grooving

    Fit saw blades matching the required groove dimensions (recommended width & depth: 13–26 mm, note: original text "13cm-26cm" is an obvious unit error for road cracks, corrected to millimeters). Adjust cutting depth and carry out grooving work.

  • Crack Cleaning

    Remove loose debris manually first, then fully blow out all dust and residues inside grooves using an air compressor or backpack blower.

  • Crack Filling

    Start pouring sealant only when its temperature stays within 170°C–200°C. The ambient surface temperature of cracks should ideally exceed 10°C. If winter surface temperature drops below 5°C, preheat groove interiors prior to filling.

  • Opening to Traffic

    Roadways can be reopened to traffic 15 to 30 minutes after completion of crack filling.

Features

High Cost Performance

Economical and practical with stable quality, realizing high-quality and low-price advantages for large-scale road maintenance projects.

Wide Temperature Adaptability (-30℃ to 60℃)

No flowing or tire adhesion under high-temperature conditions; no brittle cracking in low-temperature harsh environments.

Super Strong Adhesion

Tightly bonds with asphalt and pavement base surfaces, avoiding peeling and falling off after long-term road use.

Excellent Elasticity & Stretchability

High elongation performance enables the sealant to bear large pavement displacement and adapt to thermal expansion and contraction of roads.

Great Construction Performance

Low viscosity after heating, ensuring dense and full pouring without hollow gaps, improving overall pavement repair quality.
