ASTM Standard HDPE geocell for road construction
Description
ASTM Standard HDPE geocell for road construction
Geocell is a kind of 3D network structure through ultrasonic welding with long plastic material, and it is three-dimensional network after being expanded. Sometimes it needs to be perforated according to customer's need.It can be capable of expansion and contraction, and can be filled with earth and macadam when being stretched to network; The material is light, and it is resistant to wear, anti acid and alkali, anti-aging; It has higher literal limitation, anti-skidding, anti-deformation, and can reduce the thickness of roadbed.
Structure of Geocell
Geocell is honeycomb shaped structures, in material of HDPE, welded by high frequency ultrasonic.Being flexible, geocell can be folded in transit and outspreaded filling with sand, stone or concrete in roadbed construction.
Features of Geocell
It can be capable of expansion and contraction, and can be filled with earth and macadam when being stretched to network; The material is light, and it is resistant to wear, anti acid and alkali, anti-aging; It has higher literal limitation, anti-skidding, anti-deformation, and can reduce the thickness of roadbed.
Benefits of Geocell
1.Produces a stiff base with high flexural strength; acts like a semi rigid slab by distributing loads laterally.
2. Minimizes impact of differential and overall settlement even on low-strength subgrades
3.Increases effective structural number, reducing fill depth requirement by 50%.
4.May allow use of poor-quality granular fills in place of more costly imported materials.
Function of Geocell
1. To stable the roadbed of railway.2. To stable the roadbed of highroad.
3. To bear the load of dike or retaining wall.
4. To the improvement of shallow river way.
5. To support the pipeline and sewer.
6. For the prevention of landslide by using geocell as a heavy-duty hybrid force retaining wall.
7. To be used as independent wall, wharf and breakwater.
