What’s Asphalt Composite Grid?
Lianyi®Asphalt Composite Grid is used for the reinforcement of asphalt overlays in the construction of new pavements and rehabilitation of existing pavements.
Asphalt Composite Grid is a composite consisting of bundles of glass filaments stitched onto a polypropylene paving fabric in both the longitudinal and transverse directions using polyester (PET) yarn.The glass fibres provide high tensile stiffness, and the polypropylene fabric provides a means of maintaining the required geometry of the composite, as well as a fixing layer during installation.Once installed and saturated with bitumen, the paving fabric then acts as a waterproofing layer and also as a stress absorbing membrane interface.
Asphalt Composite Grid is a composite interlayer comprising a punched and stretched polypropylene geogrid thermally bonded to a fabric backing.The fabric backing facilitates installation and provides a long-term sealing effect -once saturated with bitumen. Owing to the 3-dimensional geometry of the geogrid, the new asphalt layer is mechanically interlocked into the geogrid’s wide apertures, thus providing reinforcement, stress relief and sealing functions.
Asphalt Composite Grid is a large aperture or standard aperture composite, typically used at a lower structural level,under base course and binder course layers.
Asphalt Composite Grid is a composite interlayer comprising a grid of glass filament bundles stitch bonded to a non-woven fabric.The high modulus glass filaments provide high absorption of stress at low strains.After being saturated with bitumen the fabric performs a sealing function.Asphalt Composite Grid provides reinforcement, stress relief and sealing functions.
Asphalt Composite Grid is a composite interlayer comprising a glass yarn grid stitch bonded to a lightweight backing fabric. The high modulus glass filaments provide high absorption of stress at low strains. The lightweight backing fabric is only present to assist with adhesion during installation and subsequently permits intimate contact between overlying asphalt and the underlying surface.
Asphalt Composite Grid consists of a glass yarn grid combined with a polymer modified bitumen membrane.The underside of the Asphalt Composite Grid includes an adhesive coating, while the upper side is treated with a protective layer of quartz sand.The adhesive layer is protected during storage by a peel-off release film.
Asphalt Composite Grid consists of a polymer modified bitumen membrane that is treated on the surface with a quartz sand, and the underside is coated to protect the product for storage and handling.
Asphalt Composite Grid does not require specialist installation and can be affixed to most sound substrates using the adhesive coating on the Asphalt Composite Grid product, or alternatively can be installed by heat activating the Asphalt Composite Grid product using a flame torch.
Features Of Asphalt Composite Grid
*High tensile strength and low elongation
.
*Minimum viscous elongation in order to assure long term reductions in the incremental plastic deformation of the asphalt layer
*High flexibility and drapability
*Easy to fix to the support layer with a tack coat spray and good adhesion to the support
*The connection between the upper and lower asphalt layers is assured by the tack coat, without creating any separation
Advantages Of Asphalt Composite Grid
*Increase road service life and save cost
*Prevent fatigue cracking and reflection cracking
*High-temperature resistant rutting
*Reduced rutting
*Initial and long-term cost savings compared with traditional rehabilitation methods
*The optimal interlayer type for the solution due to our diverse range of interlayer products
Applications Of Asphalt Composite Grid
*Reinforced asphalt overlay
*Asphalt pavement reinforcement
*Asphalt road construction
