Nonwoven paving fabrics have been used in asphalt overlays for more than three decades. Even though these nonwoven fabrics have been widely and successfully used in a variety of design and construction situations, there is no synthesis of their performance. In addition, current pavement structural-design methods do not provide a rational basis for considering the benefits of including paving fabrics in a pavement structural-section design. These two factors—limited performance data and lack of a design approach—have restricted the consideration and application of paving fabrics. These same limitations also have resulted in a lack of consistent consideration of the paving-fabric option in pavement management systems. The available literature on the uses and effectiveness of paving fabrics is synthesized. The information is based on a literature survey of more than 200 references conducted during the last 2 years to establish the benefits of using paving fabrics in pavement overlays as well as to acknowledge the results and findings of past successes and failures. After the literature review, a telephone survey of experienced users was conducted to determine the basic performance of nonwoven fabrics in asphalt-concrete-overlay performance. A synthesis of current practices and results is presented.
