Dongkai - Model TGSG-PP -Biaxial Geogrid

For over 30 years, biaxial geogrids have been utilized in pavement construction and soil stabilization projects throughout the US and worldwide. Dongkai innovative geogrid is made from extruded polypropylene which provides superior stiffness, aperture stability and interlock capabilities for structural reinforcement of paved and unpaved roads.

Lateral spreading of base course aggregate or subbase material is the most critical and common failure in pavement structures. Using Biaxial geogrid stabilizes aggregate soil through confinement and introduces tensile strength, and effectively reduces this spreading. It also allows for an increasing bearing capacity and load support capacity, resulting in improved structural performance and pavement life. Additionally, aggregate thickness can be reduced by 50% with the use of biaxial geogrid.

• With high tensile strength in longitudinal and transverse directions
• This structure can provide a chain system to provide more efficient bearing and spreading reinforce for the soft soil.

• Distribution of loads and therefore reduction in stress concentration over the soil.
• The geogrids structural junctions, rigid ribs and thick walls help lock aggregate, increasing its shear resistance.
• As a result when a vertical load is applied the aggregate is restrained by the ribs reducing deformation. (Lateral Restraint)
• Decrease in long term deformation (creep).
• Increase in load distribution. (Bearing Capacity Increase)
• Controls differential settlement.

• Basal reinforcement of embankments
• Veneer reinforcement
• Reinforcement of granular road base and subbase
• Area stabilization
• Trackbed stabilization
• Load transfer platforms
