This synthesis will be of interest to pavement designers, maintenance engineers, and others interested in methods and procedures for reducing reflection cracking of asphalt overlays. Information is provided on the use of paving fabrics and membranes in pavement rehabilitation. Reflection cracking of pavement overlays results in decreased pavement performance with respect to ride quality, structural support, skid resistance, and safety. The use of fabrics is one of the alternatives that are available to reduce or delay reflection cracking. This report of the Transportation Research Board describes the experiences of agencies in the use of fabrics and membranes for reduction of reflection cracking.

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.

Iowa's first field application of synthetic engineering fabrics was on research project HR-158, "Prevention of Reflective Cracking in Asphalt Overlays". This research placed in September 1971 used three different engineering fabrics. A final report concluding generally favorable performance was distributed in May 1977. There have been a number of Iowa engineering fabric installations since that initial project

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 report documents the installation of three commercially available paving fabrics for the reduction of reflective cracking in asphalt overlays. The fabrics installed were Paveprep, Glassgrid, and Tapecoat. The test section is in Willcox, Arizona, on State Route 186. The Willcox rehabilitation project, RS-274-(8)P, involved milling and replacing 2 in. of asphalt concrete, and placing pavement reinforcing fabric. A total of 600 linear feet of each product was placed over transverse cracks, and an additional 100 to 300 ft of each product were placed over random cracks. Markers were placed on the curbs to help monitor the performance of the fabrics during the next 3 years. Problems which occurred during installation of the fabrics are described.
