HDPE UX Geogrid ASTM Stanadard (1.1~2.0M)

Introduction

Processed of high density polyethylene (HDPE) extended warp, it has great tensile strength. The structure can provide a chain modulus which suit for long-term reinforcement of basement loading. With high tensile strength (>150mpa) , it suits for different kinds of soils.



Purpose

It's a kind of high strength geomaterial which has been applied in hydraulic, highway, railway, buiding area, etc. it has the characteristics as followings:

1. Enlarge road loadings; lasting the life of road;

2. Bear the greatest loading change;

3. Prevent the road from cracks and deformation;

4. Reduce the protection fares;

5. With embedding way, it can save investment about 40% as well shorten construction time;

6. Reduce the structure layer thickness about 36% ;

7. Convenient construction, low costs.



Polymer:

High density polyethylene



Resistance to ultra-Violet light

A high level of resistance to UV light is given by the incorporation of more than 2% of weathering grade carbon black, well dispersed in the polymer matrix. These products may be used for many years in exposed conditions.



Chemical and biological resistance:

Uni-axial geogrids are manufactured from high density polyethylene which is unaffected by all chemicals including acids, alkalis and salts, normally found in soils. Also, it is not a nutrient, therefore these not affected by microorganism in the soil.



Creep performance:

A good creep performance under sustained loading is essential for the use of geogrids in critical structures such as walls, abutments and steep embankments.
