INTRODUCTION

The product is made of polymer modified asphalt as a waterproof layer and a bonding layer where the surface is covered with aggregate material made of basalt particles. The self-adhesive layer of the polymer modified asphalt can be well bonded with the asphalt pavement at the beginning of the restoration. Under the rolling and pressing action of the subsequent traffic flow, the basalt particles squeeze into the crack effectively, integrate with the original pavement, and seal the crack and edges of potholes.

After restoration, the tensile strength and rut resistance is equal to or of better standard than that of the new asphalt pavement where they are resistant to weather changes and provide a long-lasting seal. The repair and construction is simple, using minimal machinery and tools. Once it has covered the cracked surface, the road can be open for traffic immediately.
