Light-Duty Logistics Truck Parking Lot on Silty Soft Ground

Cellular confinement systems for subgrade stabilization

Light-Duty Logistics Truck Parking Lot on Silty Soft Ground

1. Project Overview

Commercial logistics parking lot for light trucks and delivery vehicles. The site is low-lying with silty soft soil, prone to ponding and uneven settlement. The owner requires a permeable pavement system without concrete hardening.

2. Engineering Challenges

Differential settlement under static and intermittent vehicle loads; surface ponding in rainy seasons; demand for low-cost eco-friendly pavement.

3. Selected CCS Specification

150 mm textured HDPE CCS; sheet thickness 1.3 mm.

4. Key Construction Points

- Subgrade trimming and compaction; lay separation geotextile.

- Unfold and anchor CCS; fill with graded gravel, compact layer by layer.

- Reserve drainage channels at site boundaries.

Implementation Results

✅ Wheel loads evenly distributed; differential settlement reduced by 58%.

✅ Permeable structure eliminates surface ponding.

✅ Comprehensive cost cut by 32% compared with concrete pavement, construction period shortened by 40%.

✅ Flexible structure adapts to minor foundation deformation without cracking.
