• Abstract:
  This report covers an experimental feature where a geotextile fabric was used in an attempt to retard reflective cracking over severe thermal cracks. the application evaluated here is different from previous geotextile use in Oregon. It is the first time that narrow strips of fabric have been used instead of continuous full-width fabrics. The cracks were covered with 24-inch wide strips of nonwoven geotextile fabric and the noverlaid with 2-1/4 inches of dense graded polymer modified asphalt concrete. ; One year after the overlay was constructed, many of the cracks have reflected through. There is no apparent difference in performance between the test section where geotextiles were placed and the control section where the cracks were left untreated.
