The practice of geogrid production line equipment shows that the corresponding crack energy of a horizontal crack with changed direction can move 0.6m from its starting point, and the reinforced material with a width of more than 1.5m helps to ensure that the energy is completely dissipated on both sides of the crack. Therefore, the anti crack paste, a geotechnical material with high strength and low elongation, mainly has good anti crack effect.

The temperature shrinkage crack is usually caused by the sudden drop of temperature, the stress relaxation of the mixture can not catch up with the increase of temperature stress, and the bending tensile strain at the bottom of the layer exceeds the bending tensile strain.

The geogrid has the characteristics of small elongation and is applied to subgrade reinforcement treatment. Because the polyester warp knitted geogrid is flexible, it can bear large tensile stress.

It is arranged in the tensile deformation zone of the soil, and the tensile stress of the drawing is transmitted to the polyester warp knitted geogrid, so that the reinforcement is called a tensile member. In the process of rolling, when the reinforced soil is under load, the granular materials in the grid mesh are wrapped with each other, and the materials above and below the grid can be organically combined by embedding.

The use effect of glass fiber grating is closely related to the treatment of paved pavement. Before paving, the substances on the pavement that may affect the bonding strength between the grating and the bottom layer, such as grease, paint, sealing material, water stains, dirt, etc., must be completely removed to make the paved surface clean and dry. The pressure sensitive back abdomen on the glass fiber grating is a water-soluble substance. If there is water trace on the pavement, it should be paved after the pavement is dry. Before the grid is laid, tack coat oil shall be sprayed. If emulsified asphalt is used for tack coat oil, the grid shall be laid after complete demulsification and drying.
