Grouting asphalt is the use of traditional asphalt to fill cracks in road pavements. Traditional asphalt is easy to flow at high temperatures and brittle at low temperatures. However, with the improvement of road maintenance product technology in recent years, Hansheng asphalt road sealant which can "heal" road cracks well has appeared. Good quality road sealant has a good maintenance effect on road cracks.

Construction method:

1. Choose the appropriate sealant according to the road conditions and climate: The sealant is greatly affected by the local climate environment and pavement cracks. Therefore, only a suitable sealant can have a good sealant effect on pavement cracks.

2. Crack grooving: Use special grooving equipment to dig a groove with a width ratio of 1:1 or 1:2 along the crack, which can be determined according to the crack condition or consulting technical personnel.

3. Notch treatment: cut the notch and clean it with a steel brush and an air compressor, and remove the loose particles and debris in and around the notch. And keep the notch dry to ensure the bonding of the sealant.

4. Sealant filling: The sealant must be filled with special equipment heated by heat-conducting oil, and the filling must be fully filled from the bottom to the last. Capillary crevices or cracks can be treated with pipette tips or flat tip seals.

5. After the crack is poured, the traffic should be opened after the sealant is fully solidified (usually 30-60 minutes), and the traffic can also be opened after the curing material is sprayed on the surface of the crack.

Precautions

1. When slotting, it is best to ensure that the width is 1-1.3cm and the depth is 1.2-1.5cm;

2. For roads that need to be grouted, it is best to land without rain for 24 hours before and after. To ensure the dryness of the road surface.

3. When filling the joints, make sure that the melted joint glue overflows part of the cracks, so as to achieve the perfect fit between the pavement joint glue and the road surface.
