• Abstract:
  This document presents findings from a three-year, full-scale, field research project ; aimed at determining the benefits of using geosynthetic reinforcements to improve the ; performance of flexible pavements constructed over poor subgrade soils. The test site, known as ; the Marked Tree site, is an 850-ft (258-m) long segment of low-volume frontage road along ; Highway 63 in the town of Marked Tree, Arkansas. The site, constructed in 2005, consists of ; seventeen 50-ft (15.2-m) long flexible pavement test sections with various types of geosynthetic ; reinforcements (woven and nonwoven geotextiles, and geogrids), which were all positioned at ; the base-subgrade interface, and two different nominal base course thicknesses 6-in (15.2-cm) ; and 10-in (25.4-cm). One section in each nominal base course sector was left unreinforced to ; allow for monitoring of the relative performance between reinforced and unreinforced sections of ; like basal thicknesses.
