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.
