摘要

Nine instrumented flexible pavement test sections were constructed in a rural secondary road in southwest Virginia. The 15.25 m long test sections were built to examine the effects of geogrid and geotextile stabilization. Three test sections were constructed using a geogrid, three with a geotextile, and three were non-stabilized. The test section base course thicknesses ranged from 10.2 cm to 20.3 cm and the hot-mix asphalt (HMA) thickness averaged 8.9 cm. Geosynthetic stabilization was placed on top of the subgrade layer. An extensive instrumentation infrastructure was constructed to place all instrumentation, cabling, and data acquisition facilities underground.
