Geotextile Fabrics under an Asphalt Concrete Overlay to Retard Reflective211 Cracking. Experimental Features Project OR-91-03

摘要

In 1991, the City of Portland selected a section of East Burnside from 39th211u001eAvenue to 47th Avenue to grind-out and overlay asphalt concrete over an old 211u001ePortland cement concrete (PCC) pavement. Geotextiles were used to provide 211u001ereinforcement and retard reflective joint cracking. A test section on the 211u001eeastbound lanes of Burnside between 44th Avenue and 45 Avenue was placed in 211u001eSeptember 1991. The test section included four cracks, which were covered with 211u001eGlasgrid 8501 or Polyguard NW-75. A control section in the westbound lanes 211u001ebetween 44th and 45th Avenue was also constructed about the same time. The final 211u001einspection was completed in June 1998.
