PP Uniaxial Geogrid
PP Uniaxial Geogrid: ultimate tensile strength 30kN/m to 300kN/m, PP geogrids (uniaxial) Range: biaxially monolithic and monolithic molded geogrids of bending stiffness consisting of PP - polypropylene or HDPE - polyethylene by means of a unique punching and drawing process.
1. to reinforce old asphalt concrete pavements and asphalt layers to prevent damage.
2. used to rebuild cement concrete pavement into composite pavement and inhibit the reflection caused by block shrinkage.
3. Used for road expansion, remediation works and cracks caused by uneven location and deposition of old and new combination; and
4、Used in soft ground reinforcement treatment, which is favorable to soft ground water separation and condensation, effectively inhibit deposition, evenly distribute stress, and improve the overall strength of roadbed;.
5、It is used to prevent shrinkage cracks caused by new road semi-rigid grass-roots level, and to reinforce and prevent pavement cracks caused by reflection of foundation cracks
PP Uniaxial Geogrid is a kind of high polymer as the main raw material, adding certain anti-ultraviolet, anti-aging additives, after one-way stretching to make the original distribution of scattered chain molecules re-directional arrangement of linear state, by extrusion and then punching the rules of the hole mesh, and then longitudinally stretched and become high-strength geosynthetics. This process makes the polymer into a directional linear state and form a long oval mesh integral structure with uniform distribution and high nodal strength.
Product characteristics
1. High uniaxial tensile strength, good creep resistance and stable chemical properties.
2. Large friction coefficient with gravel.
Product function
1. Uniaxial geogrid is a kind of high-strength structural material used for roadbed reinforcement of highways, municipal roads and railroads.
2. It is applied to the reinforcement of dams, rivers and seawalls.
3. It is applied to the fencing of orchards, vegetables, animal husbandry, land and so on. Safe and convenient to use, and easy to dismantle, beautiful appearance;.
4、Applied to retaining and wall reinforcement projects of highway, municipal road, railroad, river and coastal area;.
5. Mainly used in retaining walls, bridge abutments, slope projects, etc.; and
6. Retaining walls and bridge abutments are stressed structures, they bear all the external loads, active earth pressure, dynamic loads on the upper part of the structure, temperature stresses, etc., in the larger long-term tensile reinforcement, as well as repeated dynamic loads, so that the molecular structure of the material fatigue, in the performance of attenuation, accelerated grid aging. In order to avoid the deformation caused by creep of the reinforcing material, it is best to choose high density polyethylene (HDPE) as the raw material of uniaxial geogrid.
