The quality of grouting construction is a comprehensive process of multiple factors, and each process must be strictly constructed according to the requirements. During the construction process, it is important to ensure that workers wear professional construction protective clothing and are equipped with specialized construction equipment to prevent burns and machine malfunctions from causing harm to workers.
 | Ensure that the groove depth is around 1.5 centimeters The harm of insufficient slotting depth lies in the fact that due to the relatively small amount of material used, in the environment of winter shrinkage, the material becomes very thin under tension. At the same time, under the repeated rolling action of the tire, the aggregate on one side of the groove was loosened, and the opening became very wide. The material that was originally bonded to the sturdy seam wall lost its function due to the loosening of the aggregate |
 | Thoroughly clean the grouting groove The material that has not been cleaned by high-pressure gas adheres to loose aggregates, causing weak bonding. Under the action of water, sand, and wheels, the material adheres to the aggregates and falls off. |
 | Heating and cleaning The groove that has not been baked at high temperatures, has not been thoroughly cleaned of moisture, and the direct combination of cold asphalt aggregate and hot melt sealant is also a reason for easy detachment |
 | Grouting operation The surface material is too thick: Due to the scraper applying a thick layer on the surface, while the bottom material is very shallow, the surface is subjected to a lot of pressure from the tire, and the amount of bottom material is small, which also cannot meet the tensile force, resulting in the material being easily pulled out. It is recommended that the material be slightly lower than the road surface when filling the seam, so that the tire cannot crush the material, and at the same time, due to the good adhesion of the material itself. It can ensure the sealing effect. |
 | Cooling time The construction temperature must be controlled at around 185 ℃. When the temperature of the hot asphalt crack sealant is below the lower limit of the recommended heating temperature range (around 185 ℃), the sealant is very viscous and cannot penetrate the crack hole well, which cannot form a good seal. If the temperature of the sealant exceeds the upper limit of the temperature requirement range, it may cause changes in the performance of the sealant, coking, and a decrease in bonding strength. Heat the sealant to the allowable temperature range, and all performance indicators of the sealant will reach their optimal state, which can fully exert the best sealing effect of the sealant. |

The relationship between road surface temperature and sealant construction temperature is an important factor in achieving good sealing effect. The asphalt crack filter hot sealant is sprayed into the pre opened groove and kept in liquid state for a longer period of time, which can allow the sealant to penetrate more through the crack channels and increase the bonding area. Due to the faster solidification rate of sealant on cold road surfaces compared to construction on hot road surfaces, it is necessary to fully consider the relationship between the two and determine the construction temperature.
When the road surface temperature drops below 20 ℃, the construction temperature should be set to the highest temperature range of 190 ℃ during construction.
When the road surface temperature is between 20-40 ℃, set the construction temperature at 180 ℃.
When the road surface temperature exceeds 40 ℃, the construction temperature should be maintained at the lowest value of the temperature range, which is 180 ℃.
After the rain, the road surface has already dried up and needs to be baked with a hot spray gun. This is because there are many factors that contribute to the source of moisture. The base layer contains moisture, and excess water from freezing and thawing, rainwater, or watering green belts seeps up through cracks and gaps. The high-pressure water formed by vehicle compaction is pumped out along the cracks, causing the sealant to fail. It is recommended to use a specially designed hot spray gun during construction in spring and autumn seasons. The hot air temperature can reach 2000 degrees Celsius, instantly evaporating the moisture in the crack area of the road surface, and heating the asphalt aggregate at the groove and groove bottom to a molten state. It can be thermally combined with the melted sealant to form a whole and resist the infiltration of moisture in the base layer.
Attention: When adding asphalt crack repair sealants, be careful to slowly pour them into the melting pot to avoid splashing materials that may burn other construction personnel. Do not fill the material box to the brim. It is best to add only the materials required for this construction or up to 75% of the capacity of the material box.
