Abstract:

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 of 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. Results, based solely on these test pavements, indicate that geotextiles are not consistently cost-effective methods to address reflective cracking. However, limited evidence indicates geotextiles reduces "pumping" after cracking does occur.
