crack sealant hot tar road repair,
hot tar road repair asphalt layer,
70 Elastic preventive road maintenance
There is a significant temperature difference between the surface layer and the base layer of the asphalt road. This will easily cause cracks when the shrinkage force generated by the temperature is stronger than the tensile capacity of the road surface.
The main function of ZTA road crack sealant is to prevent the expansion of cracks after the potting is completed, prevent the infiltration of rainwater, and reduce the further damage of the rainwater to the roadbed.
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.
|Type||Penetration/0.1mm||Softening point/℃||Flow value(mm)||Elastic recovery ratio/%||Low temperature stretching|
|Test temperature/℃||Maximum displacement/mm||conclusion|
|High temperature type||51||96||0||70||0||9.005||pass|
|Low temperature type||89||90.50||2.01||55||-20||45.600||pass|
Low density and better quality. The surface is black and shiny, increasing the length of the filling seam.
Strong bond. Not easy to fall off, good sealing effect.
Strong anti-water damage, anti-aging, anti-shedding and anti-deformation capabilities.
good stability. Not easy to segregate, no oil leakage.
Stable high and low temperature performance. High temperature does not deform and flow, low temperature does not crack.
The construction is convenient, preferably the outer film, which can be completely melted with the glue in the hot melt kettle.
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.
