In 1991, the City of Portland selected a section of East Burnside from 39th Avenue to 47th Avenue to grind-out and overlay asphalt concrete over an old Portland cement concrete (PCC) pavement. Geotextiles were used to provide reinforcement and retard reflective joint cracking. A test section on the eastbound lanes of Burnside between 44th Avenue and 45 Avenue was placed in September 1991. The test section included four cracks, which were covered with Glasgrid 8501 or Polyguard NW-75. A control section in the westbound lanes between 44th and 45th Avenue was also constructed about the same time.

The primary purpose of this project is to determine whether any of various treatments, using geotechnical fabrics and fibers, will significantly retard reflective crack formation in an asphaltic concrete overlay. Four paving fabrics, one asphalt/fiber membrane and one fiber-reinforced asphalt concrete, are the treatment alternatives being evaluated. All treatment to determine relative performance, considering cost, ease of placement or adaptability to normal overlay practice, and ability to resist reflective cracking. Field monitoring is being maintained for three years to determine overall and relative performance of each treatment.

Geotextiles (engineering fabrics) were installed at four locations in Texas to evaluate their potential as cost-effective measures to reduce or delay reflection cracking in asphalt concrete overlays. The overlaid pavements included asphalt concrete, continuously reinforced portland cement concrete, and a freshly cold-milled asphalt concrete. Test pavements were approximately 0.25 mile in length with the fabric installed edge to edge. Nine different types of commercially available geotextiles comprised of nonwoven polypropylene or polyester were tested. One woven experimental product composed of polypropylene and polyester was also tested. Resistance to reflective cracking has been evaluated for up to 10 years.

This investigation was conducted in an effort to examine the effectiveness of geotextile fabrics used in conjunction with hot mix asphalt overlays over existing hot mix asphalt pavement sections in the jurisdiction of the Engineering Department in Washoe County, Nevada. The analysis was focused on the effects of the fabric placement on cracking visible at the surface of the new overlay sections, most notable reflective cracking transferred from the existing pavement prior to the overlay. Only the surface of the pavements were explored using the visual condition survey methods utilized by the Micro PAVER software and pavement management system on multiple overlay projects constructed from 1983-2003. The distress measurements of the analysis sections were conducted prior to the overlay placement and approximately one, three, and five years, following the overlay application. The overlay thicknesses varied from 1.5-2.5 inches with and without fabric placements.--Adapted from abstract.
