Paving fabrics create a moisture barrier between older and newer layers of pavement and also slow down the reflective cracking process. The process can be installed on any surface from highways to your own driveway. Fabric installation is also less expensive than full lift asphalt overlay. Paving fabric installation involves the use of a geotextile material that is placed between the subgrade and the asphalt pavement layer to enhance the performance and durability of the pavement. The paving fabric is a non-woven or woven material made of synthetic fibers such as polyester, polypropylene or nylon, which provides reinforcement to the pavement structure by acting as a stress absorbing membrane.
The surface must be cleaned of any debris, loose rocks, or other materials that may interfere with the installation process.
A liquid adhesive is applied to the subgrade, which is the layer of soil beneath the pavement. The adhesive helps to bond the fabric to the subgrade.
The paving fabric is then unrolled onto the adhesive and spread across the entire area of the pavement. The fabric should be smooth and without wrinkles.
The seams between adjacent rolls of fabric are overlapped by at least 12 inches and heat-sealed to ensure a continuous layer. The asphalt concrete is then laid over the paving fabric and compacted to create a durable and smooth pavement surface.
Paving fabric installation is typically used for roadways, parking lots, airport runways, and other heavy-duty applications. The advantages of paving fabric installation include improved durability, reduced pavement cracking, improved pavement structure strength, and a longer pavement life. At Talley Oil, we use leading vendor pavement fabric such as the TruPave™ engineered paving mat from Owens Corning®, a pavement interlayer designed to create a moisture-resistant barrier, provide improved anti-cracking performance, and stand up to high-temperature hot-mix designs. And at the end of the pavement’s life, it’s millable and recyclable. We also use Tencate’s Mirafi® MPV paving fabrics, which are needle-punched, polypropylene, heat set, non-woven geotextiles with high asphalt absorption. When installed with sufficient asphalt cement tack coat on a properly prepared surface, Mirafi® MPV paving fabric and the tack coat form an impermeable fabric interlayer system that is fully recyclable and adds long-term life-cycle and cost benefits to your pavement.
