ZTA crack sealant can withstand the double test of high temperature and low temperature. It will not flow in high temperature weather, and will not harden in cold winter. It still has enough toughness to adapt to crack stretching caused by thermal expansion and contraction.
Road Maintenance Hot-melt Asphalt Sealant is a composite modified bituminous sealant. With the advantage of fast hot-melt, strong adhesion, super performance of high and low temperature, easy construction performance and good anti-deformation recovery performance, Crack sealant can effectively seal pavement cracks and joints and maintain the sealing effect for a long time. Besides traffic can be restored immediately after the completion of construction.
To repair the cracks in asphalt pavements perfectly, the key is to choose a suitable type of sealant. Choosing the appropriate sealant as the material for pavement crack repair according to different regions & different climatic conditions and pavement crack characteristics. The product is divided into high temperature type, common type, low temperature type, cold type and severe cold type.

|Low temperature type||89||90.50||2.01||55||-20||45.600||pass|
Strong bond. Not easy to fall off, good sealing effect.
Stable high and low temperature performance. High temperature does not deform and flow, low temperature does not crack.
Good construction and workability, no impurities do not block damage to the machine.
Long service life and less maintenance. The service life can reach 3-5 years, which is 2-3 times the service life of other materials.
1. Before filling, ensure that the cracks are dry and there is no water or rain within 24 hours before and after potting.
2. Whether to slot the joints according to customer requirements. Dust must be purged before potting.
3. When the temperature during the construction of the joint is lower than 5 °C, the crack should be preheated by a hot spray gun.
4. The filling joint is constructed by a filling machine with a stirring function. The sealing glue should be continuously stirred during the construction process. The sealing glue needs to be heated to 180-190 °C before the filling can be applied.
5. After the construction of the joint, it should be allowed to stand for 20 minutes to open the traffic. If it is open traffic immediately, it needs to sprinkle a small amount of fine sand or talcum powder, cement and other spacers to prevent the glue from sticking to the tire.
6. After the filling construction is completed, the sealing machine should be cleaned and the sealant should be avoided in the filling machine. After each section of the jointing construction, the filling machine should be cleaned.
