Geogrid vs. Conventional Pavement Reinforcement: A Comparative Study of Material Properties, Construction Techniques, and Performance Outcomes

(Subtitle: Technical and Economic Evaluation of Polymer Geogrid Solutions versus Traditional Cement/Asphalt Methods for Roadway Strengthening)

Key Comparison Metrics:

1. Material Characteristics

• Geogrid: High-tenacity polypropylene (≥50kN/m tensile strength) with<3% strain at failure

• Traditional: Cement-treated base (CTB) with 2.5-4.5MPa compressive strength

2. Construction Efficiency

• Geogrid: 40% faster installation using roll-out deployment (300m²/hour)

• Traditional: 7-day curing requirement for CTB layers

3. Structural Performance

• Geogrid: 60% reduction in reflective cracking (10^6 ESALs)

• Traditional: 20-30% higher rutting potential in high-temperature conditions

4. Lifecycle Economics

• Geogrid: 15-20% lower whole-life costs in soft soil applications

• Traditional: 30% higher maintenance frequency in freeze-thaw zones

Engineering Value Proposition:
This analysis demonstrates how geogrid reinforcement:

• Extends pavement service life by 5-7 years

• Reduces base course thickness requirements by 25%

• Enables construction over marginal soils (CBR<3)
