Stress Absorbing Membrane Interlayer - SAMI
A high-quality needle punched Non-woven Geotextile that, when installed on a bituminous tack coat, performs as a Stress Absorbing Membranes Interlayer (SAMI) and inhibits the upward propagation of cracks from the underlying pavement into the overlay. This condition is often referred to as reflective crack control.
Paving Fabric offers optimum tensile strength with high corresponding elongation. This ensures that the saturated Non-woven will absorb stress but still follow the contours of the underlying surface.
Paving Fabric exhibits critical bitumen retention properties that ensures sound adhesion between the old and new surfacing layers. This encourages bitumen to be drawn up from the tack coat and provides for an easy installation that results in a strong bond being developed between the fabric and underlying surface.
Forms a permanent waterproof barrier that prevents moisture or water penetration into the road base from above. This protects the subsoil from water intrusion through the pavement and any subsequent reduction in bearing capacity. The product is available in several widths.
| On Site Preperations | ||||||||
| Surface PreparationThe existing pavement surface has to be cleaned to remove dirt, oil, water and other foreign bodies. Large holes and cracks greater than 5 mm should be filled with warm asphalt or other suitable filler. | ||||||||
| Tack CoatThe correct quantity of bituminous tack coat should be sprayed onto the existing pavement surface. | ||||||||
| LayingPaving fabric can be unrolled manually or mechanically. Mechanical unrolling helps minimise the number of wrinkles due to the fabric being stretched slightly during installation.It is recommended that Paving fabric be unrolled so that the labelled surface of the fabric is in contact with the pavement surface.Overlaps should be between 10 cm and 15 cm, and should be made in the paving (driving) direction. The use of extra bituminous tack coat is recommended between overlaps. Heavy trafficking on the Paving fabric should be avoided during installation. Wrinkles greater than 2 cm to 3 cm high, should be cut, open and laid flat. | ||||||||
| Asphalt Overlay InstallationOverlay installation can follow on immediately after the Paving fabric placement. A hot asphalt temperature is required to soften the underlying bitumen and to ensure maximum saturation of the Paving fabric in order to create the membrane effect. The temperature of the asphalt should not exceed 140C when it comes into contact with the Paving fabric. An asphalt overlay thickness of 5 cm is recommended.

| Method to Use | ||||||||||||||||||||
| After the necessary protective coating/wrapping is given, pieces of PETROSHIELD are wrapped around the pipe (each piece overlapped by approximately 10 cm) and secured in place with polyester/polypropylene straps and buckles. Alternatively, self-adhesive polypropylene tapes may be used.

TUFLEX Monofilament Knitted Fabric is a Raschel Knitted structure manufactured from 100% virgin polyethylene (HDPE) UV stabilized material. Its unique lock stitch construction allows the consumer to cut the fabric without the worry of the fabric unraveling. Monofilament yarn in both the warp and weft direction maximizes the strength properties of the fabric.
