　　What is the main function of anti cracking stickers in road white to black conversion

　　Replace the traditional asphalt grouting process with self-adhesive crack prevention stickers. Dealing with asphalt pavement cracks is a major improvement in current highway maintenance technology. Traditional techniques are limited by the low-temperature brittleness and high-temperature softening of asphalt materials, and the repaired cracks will re crack after a year of surface expansion and contraction with changes in temperature. The existence of this problem has increased the workload and material costs of road maintenance, while self-adhesive crack prevention stickers overcome the shortcomings of traditional asphalt materials in terms of material performance.

　　1. Introduction to anti cracking stickers

　　Crack resistant stickers, also known as anti cracking stickers, are composed of asphalt based polymer, high-strength tensile tire base, and high-strength fabric that is resistant to high temperatures and compatible with asphalt. It has good compatibility with asphalt pavement, high bonding strength, no brittleness, and no deformation at high temperatures. The construction operation is simple and flexible. Simply remove the isolation paper, stick it to the road surface along the shape of the crack, and press it tightly to effectively deal with the accumulated cracks and significantly extend the service life of the pavement. Crack prevention stickers are an organic and comprehensive application of several measures to prevent cracks on highways, and are also an upgraded product for crack prevention and waterproofing on white to black highways.

　　2. Performance of anti cracking adhesive material

　　The anti cracking sticker overcomes the interface caused by the simple use of geotextile and fiberglass grating for crack resistance, which affects the stress condition of the asphalt surface layer and affects the crack resistance ability; The use of geotextiles and fiberglass grilles during paving has overcome the problems of displacement and folding, which affects the adhesion of upper and lower structural layers. For asphalt based stress absorbing films that can only absorb stress but cannot resist residual stress or disperse stress, anti cracking stickers provide a good solution. This unique structure not only prevents cracks, but also has a unique effect on waterproof infiltration, especially for ice water infiltration after road surface frost cracking, which has good low-temperature performance.

　　When laying hot asphalt mixture with anti cracking coating, the fabric will not undergo high-temperature deformation. The high polymer will seep out from the gaps of the fabric after hot melting, and it will bond very well with it. The lower coating has a sufficient amount of high polymer to fill the potholes on the base surface after melting, ensuring the bonding force with the base surface. The stability of the lower coating and the tire base ensures the formation of a relatively uniform composite interlayer, which meets the requirements of crack resistance and waterproofing.
