Asphalt road crack sealant, also named road joint sealant or pavement sealant, is a hot-melt elastic sealing material. It is modified from heavy-duty asphalt with SBS polymer, rubber powder, anti-aging agent and stabilizer. Supplied in solid blocks, it forms an elastic sealing layer after melting and cooling. It blocks rainwater, de-icing salt and silt from penetrating into pavement base and stops crack propagation. It is a key material for preventive road maintenance. Five grades (high-temperature, normal, low-temperature, cold, severe-cold) are available for service temperature -40℃～80℃, complying with JT/T 740-2015 standard.

1. Asphalt pavement: Sealing transverse and longitudinal cracks of highways, national & provincial roads, municipal roads.
2. Cement-concrete pavement: Filling expansion joints, construction joints and settlement joints.
3. Special pavements: Bridge decks, factory roads, parking lots, plazas, airport runways.
4. Projects: Pavement preventive maintenance, old road crack repair, joint sealing for new-old pavement connection.
1. Crack Cleaning: Remove dust, gravel and debris inside cracks by crack-cleaner and air blower. Ensure cracks are dry and clean. Dry wet positions thoroughly.
2. Material Melting: Put solid sealant blocks into melter, heat to 180-200℃ and stir evenly. Avoid over-heating and carbonization.
3. Crack Pouring: Pour molten sealant into cracks with pouring gun. Fill fully and compactly. Keep surface slightly 1-2 mm higher than pavement to compensate cooling shrinkage.
4. Cooling & Curing: Allow natural cooling until full curing.
5. Traffic Opening: Remove excess material after curing, then reopen traffic. Extend cooling time under low-temperature conditions.
