Abstract:Last year, the City of Portland decided to place geotextile fabrics under asphalt concrete overlays for pavement reinforcement and crack retardation. The City expected the following benefits from using the fabrics: retardation of reflective cracks, reduction of water infiltration into underlying cracks, retardation of vegetation growth in cracks, improvement of pavement surface quality, and reduction of future pavement maintenance costs. City staff will evaluate the cost effectiveness of the geotextile fabrics for five years.
