Gravel seal technology is a thin-layer construction technique used to establish road surface functionality. The basic method is to first spread an appropriate amount of asphalt binder evenly on the road surface through special equipment, then densely distribute gravel with relatively uniform particle size on the asphalt layer, and then roll it so that an average of about 3/5 of the gravel particle size is embedded. Asphalt layer.
Gravel sealing technology has the advantages of excellent anti-slip performance and effective water sealing effect, low cost, simple construction technology, and fast construction speed, so this technology is widely used in Europe and the United States and other countries.

Gravel sealing technology is suitable for:
1.Road maintenance cover
2. Create a new road wearing layer
3. New medium and light traffic road surface layer
4. Stress absorbing adhesive layer

Technical advantages of gravel seal:
1. Good water sealing effect
2. Followers have strong deformation ability
3. Excellent anti-skid performance
4. Low cost
5. Fast construction speed

Types of binders used for gravel sealing:
1. Dilute asphalt
2. Emulsified asphalt/modified emulsified asphalt
3. Modified asphalt
4. Rubber powder asphalt
