Abstract: Thin asphalt concrete overlays are susceptible to reflective cracking, which is the migration of the cracks in an old pavement into and subsequently through its overlay. To find a remedy to this problem, the Texas Highway Dept. applied 330,000 yd² of Petromat non-woven polypropylene fabric in four test sections of I-20 near Pecos, Texas, covering nine miles of the four-lane highway. The article tells why and how the fabric was installed and what Texas expects to learn from the test.
