Industry Comparison

Application Scenarios

Typical application environments for Best Biaxial Plastic Geogrid across stakeholder groups:

• Highway base and subbase reinforcement for EPC contractors

• Industrial yard and port pavement stabilization for developers

• Railway formation improvement for infrastructure companies

• Airport runway subgrade reinforcement for civil contractors

• Temporary and permanent access roads for mining projects

Core Pain Points and Engineering Solutions

• Weak subgrade soils: Best Biaxial Plastic Geogrid increases bearing capacity through aggregate interlock.

• Differential settlement: Biaxial structure distributes loads evenly in two principal directions.

• Excessive rutting: Restrains lateral movement of aggregates, improving pavement life.

• High maintenance cost: Extends service intervals and reduces repeated rehabilitation.

Risk Warnings and Mitigation Measures

• Risk of insufficient overlap between rolls – maintain minimum 300 mm overlap.

• Risk of UV exposure during storage – store under protective covers.

• Risk of mechanical damage from sharp aggregates – inspect base course before placement.

• Risk of improper tensioning during installation – apply manual pre-tensioning where specified.

Procurement and Selection Guide

1. Define project load class and traffic category.

2. Conduct subgrade CBR and modulus tests.

3. Select tensile strength grade based on design calculation.

4. Verify junction efficiency through certified lab reports.

5. Confirm roll dimensions for onsite handling capacity.

6. Request long-term creep data and reduction factors.

7. Check compliance with ASTM and ISO project standards.

Engineering Case Example

A logistics park development project installed Best Biaxial Plastic Geogrid over a 35,000 m² soft clay subgrade. The design incorporated 150 mm crushed stone base over the geogrid layer. Post-construction plate load tests indicated a bearing capacity increase of more than 40%, with reduced surface deformation under heavy axle loads.
