Methodology Of Installation
Road Preparation
Complete crack sealing, pothole filling, base repairs, leveling course application, etc.
Broad Surface Condition
*Surface must be: dry, clean and dust-free.
*The road surface temperature must be between 5℃ and 60 ℃
*On asphalt surfaces less than 24 hours old, the surface temperature must be between 5℃ & 50 ℃
*Local guidelines should be followed for paving temperature range
Product Preparation
In order to preserve adhesive properties, fiberglass geogrid must be stored inside a dust-free environment and kept dry at the job site. Fiberglass geogrid must not be transported or stored at temperatures greater than 82 ℃
Methods For Installation
A. With Pressure Sensitive Adhesive
*Load roll onto front or back of tractor. Always load in such a way that allows the placement of mesh with the self-adhesive side down.
*Roll only with a rubber-tired roller to activate adhesive. Roller tyres must be kept clean.
*Apply tack coat/emulsion as per project requirements and pave once cured
B. Without Pressure Sensitive Adhesive
*Apply the track coat/emulsion in accordance with project specifications.Once the tack coat/emulsion has cured, proceed with the laying of glass fiber grid .
*Load roll onto front or back of tractor.Always load in such a way that allows the placement of glass fiber grid without any wrinkles.
*Roll only with rubber-tired roller and pave the asphalt layer.
Important Notes
*Because fiberglass geogrid is considered a skin irritant, workers should wear gloves while handling fiberglass geogrid.
*Asphalt Fiberglass grid can be custom cut to fit around structures by using a sharp utility knife.
*Asphalt Fiberglass grid must be applied without ripples. Sufficient tensile strength during application will eliminate this problem.
*Overlap at end of roll joints 75-100mm. Ensure that the overlaps are shingled in the direction of paving.
*Overlap longitudinal joints 50-75mm.
*Prior to paving, only construction and emergency vehicles shall be allowed to drive on installed asphalt fiberglass grid.
*Damaged sections shall be removed and patched, taking care to underlap the full roll.
*All glass fiber grid placed in a day shall be covered with asphalt immediately, within permissible laying temperatures to a minimum compacted thickness of 40mm.
*Avoid pushing of the asphalt delivery vehicles with the paver, particularly on uphill gradients.
*Prevent asphalt delivery vehicles from executing sharp turns, accelerating or braking on the glass fiber geogrid .

Composite Geomembrane Construction Precautions
*It should be used in an embedded manner, and the covering thickness should not be less than 30cm
*The entire anti-seepage system should have: The responsibility lies with the base layer, anti-seepage layer, transition layer and protective layer
*The soil should be solid to avoid uneven settlement and cracks. The turf and tree roots within the anti-seepage range should be removed. A protective layer of fine-grained sand or clay is laid on the surface in contact with the geomembrane。
*When laying the composite geomembrane , do not pull it too tight. It is better for the parts buried in the soil at both ends to be in a wavy shape. Especially when anchoring with rigid materials, a certain amount of expansion and contraction should be left
*During construction, it is necessary to avoid direct impact of stones and heavy objects on the composite geomembrane.It is best to lay the geomembrane and cover the protective layer simultaneously during construction
The laying of composite geomembrane
*The surface of the composite geomembrane should be cleaned and laid as a whole, without any unevenness or sharp objects such as stones, iron wires or wooden sticks. Herbicides should be sprayed to kill weeds
*The composite geomembrane is best laid in a certain direction. At the same time, it should not be stretched too tightly. A certain allowance should be left to adapt to the deformation of the base
*A certain width of HDPE Geomembrane and HDPE Geomembrane bonding layer should be reserved on both sides of the composite geomembrane. When laying, the direction of each unit of composite geomembrane should be adjusted properly to facilitate the welding of two units of composite geomembrane
*After the composite geomembrane is laid, it should be pressed down with sand belts to prevent wind movement, which may affect the welding of the edge of the composite geomembrane in the next step.

What’s Composite Geomembrane?
Lianyi® Composite Geomembrane is a popular geosynthetic material made by calendering and hot melting two or more materials, namely geotextile (long fiber needle punched non woven geotextile , short fiber needle punched non woven geotextile,woven geotextile,etc.) and high molecular materials (HDPE geomembrane, LDPE geomembrane, EVA geomembrane, etc.).

One geotextile one geomembrane, geotextile: 100-1000g/m2,geomembrane:0.2-2.0mm
Features Of Composite Geomembrane
Composite geomembrane uses geotextile instead of granular materials as the protective layer of the geomembrane to protect the anti-seepage layer of the geomembrane from damage, reduce the gradation requirements of the cushion layer particle size, and also play a drainage role
The composite geomembrane has a large friction coefficient, which can prevent the sliding of the covering layer. Compared with the simple HDPE film, the non-woven fabric in the composite geomembrane has a larger friction coefficient. The composite geomembrane can increase the slope ratio and reduce the occupied area
The mechanical strength of the composite geomembrane, such as tensile, tear, puncture and puncture resistance, is high
Composite geomembrane has a certain degree of deformation, and the stress transmission and dispersion caused by the concave-convex defects of the base layer are relatively fast, so it should have a strong capacity
The pore pressure and buoyancy force on the contact surface between the composite geomembrane and the soil are easy to dissipate
Composite geomembrane has a certain heat preservation effect, reducing the damage to the geomembrane caused by soil frost heaving, thereby reducing soil deformation
The composite geomembrane is laid in an embedded manner and has excellent anti-aging performance, reducing the maintenance and upkeep of the project
The construction of composite geomembrane is convenient, reducing the transportation volume, lowering the project cost and shortening the construction period
