| 摘要： | 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 final inspection was completed in June 1998. |
