Paving Interlayers are engineered geotextile fabrics placed between layers of asphalt concrete (AC). Since 1965, the Paving Interlayers have had an outstanding record of improving pavement performance while reducing maintenance and roadway life-cycle costs. Paving fabric systems are currently being used at a rate of over 15,000 equivalent lane miles per year in North America alone. Paving Interlayer Systems extend the life of new AC pavements and AC overlays. When placed between layers of AC pavement, these systems becomes an integral part of the roadway section, forming a barrier to water infiltration and absorbing stresses to reduce reflective and fatigue cracking of the new asphalt surface layer. Benefits As much as 100 million square yards of Interlayer Paving Systems are successfully being installed every year in the United States. These interlayer systems are being used for two primary reasons: They provide a Moisture Barrier to stop surface water from entering the road base. FHWA studies show that one-third to one-half of all precipitation falling on a road surface can infiltrate through the pavement to the base and sub grade. Pavement base materials that are saturated just 10% of the time can reduce the pavements life by 50%. They form a Stress Absorbing Membrane to increase pavement fatigue life and to retard reflective cracking. Laboratory tests indicate a 100 – 300% increase in fatigue life of a pavement when used with a Fabric Interlayer. Field performance indicates a 50 – 100% delay in reflective cracking occurs with a Fabric Interlayer. Fabric Interlayers are shown to be equivalent to placing an additional 0.1 to 0.15 feet (three to four centimeters) of ACC overlay in terms of retarding crack reflection. The installation of a Fabric Interlayer System is much less expensive than placing additional asphalt or increasing roadway maintenance. Use of paving fabrics generally yields a savings in pavement rehabilitation system costs of more than $7000 per lane mile.
