1. Product introduction
Asphalt pavement curing agent is a new type of preventive maintenance or repair material for asphalt pavement. It is a modified asphalt-based regenerated and strengthened curing agent. After spraying, the aging asphalt components of the original pavement are replenished, activated, and functionally restored to prevent the further expansion of pavement diseases. It can also achieve the effect of renovating and beautifying the old pavement. The product has good penetration, wettability and waterproofing properties, making the original pavement achieve sealing performance and improving pavement stability and resistance to deformation and distortion.
2. Physical and chemical characteristics
Physical state: black viscous oily liquid.
Stability: Can be stored for a long time and transported under normal conditions.
3. Technical characteristics
1. Improve road stability
Enhances the stability and resistance to deformation and distortion of asphalt concrete. Reduces damage caused by repeated freeze-thaw cycles and reduces damage caused by bursting of pores or voids caused by wheel movement in wet environments.
2. Sealing performance
Special wear-resistant materials and reducing materials are added to the asphalt pavement maintenance agent, as well as its good permeability and waterproofing properties, so that the original pavement can achieve sealing performance. In addition, the asphalt pavement curing agent can seal the cavities, pores and cracks of ≤3mm in the asphalt pavement for a long time, thus giving the inner body of the asphalt road a waterproof and moisture-blocking mechanism (the upstream and backside surfaces).
3. Excellent adhesion
The use of asphalt pavement curing agent can, on the one hand, increase the adhesion of aggregates in the asphalt mixture, and on the other hand, it can effectively fill the fine cracks and partial gaps between the aggregates to achieve the water sealing effect.
4. Excellent performance
Asphalt pavement maintenance agent has good wettability with asphalt mixture and can quickly penetrate into the mixture. Generally, the penetration depth can reach more than 2cm.
5. Corrosion resistance
Pavements using asphalt pavement maintenance agents can resist the erosion of gasoline, water and other chemicals, and the protection effect is more significant for roads that are easily damaged by fuel, such as airport runways.
6. Good appearance
The use of asphalt pavement maintenance agent can restore the clean matte black appearance of the original road surface, create a good visual experience for drivers, and improve driving safety.
7. Easy construction
The construction equipment is simple and can be constructed at room temperature, even at 0℃, and can be used in both cold and hot climates.
8. Rapid curing
At normal temperature (above 5℃), it can be opened to traffic 2-3 hours after construction.
9. Low carbon and environmental protection
No heating is required during construction and no waste gas is produced.
4. Usage and dosage
1. Basic requirements
1.1 The recommended coating amount is 0.2-0.4L/m2 (related to the porosity of the road surface, the higher the porosity of the pavement, the upper limit will be used, and the higher the porosity of the road surface, the lower limit will be lower).
1.2 If there are large areas of damage, potholes, cracks and other diseases in the pre-maintenance road section, they need to be treated before using this product for maintenance.
1.3 Construction conditions: The temperature must be between -30°C and +50°C. Construction cannot be carried out in rainy or snowy days.
1.4 Construction personnel must understand how to use this material before construction.
1.5 Construction machinery:
1) For mining in small areas
