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.

0 ℃ High-temperature Grade: Suitable for inland regions with scorching hot summers and rarely sub-zero temperatures in winter. The historical extreme minimum temperature in winter is no lower than 0 ℃, and the pavement temperature rises sharply under direct sunlight in summer. It features outstanding high-temperature stability, resisting flowing and tire-sticking under high summer pavement temperature. It is suitable for crack sealing and repair of roads, parks and factory roads.
-10 ℃ Normal Grade: Suitable for areas where the winter extreme minimum temperature is generally no lower than -10 ℃ with moderate seasonal temperature difference. It is a general-purpose grade with high cost-performance, balancing high-temperature performance and ordinary low-temperature crack-resistance.
-20 ℃ Low-temperature Grade: Suitable for cold winter areas where the winter extreme minimum temperature can reach -20 ℃. This grade maintains elasticity at low temperature and is not prone to brittle cracking or peeling-off.
-30 ℃ Cold-climate Grade: Suitable for regions with long and severe winters, where the extreme minimum temperature can reach -30 ℃ and freeze-thaw cycles occur frequently. This grade delivers excellent low-temperature resilience and adapts to large temperature fluctuations, ideal for heavy-duty highway maintenance projects.
-40 ℃ Frigid-climate Grade: Suitable for alpine and extremely cold regions. The winter extreme minimum temperature can be as low as -40 ℃ with large day-night temperature difference and frozen-soil conditions. It retains good elasticity and adhesive force under ultra-low temperature without brittle cracking or joint debonding of sealant. It is widely used for maintenance of expressways and trunk roads in frigid zones.
