Abstract

Subgrade restraint design is the use of a geosynthetic placed at the subgrade/subbase or subgrade/base interface to increase the bearing capacity or the support of construction equipment over a weak or soft subgrade. The conventional design criteria of unpaved roads require providing adequate base course or aggregate cover material to prevent bearing capacity type failure. Geogrids and high-strength woven geotextiles can increase bearing capacity of a pavement structure, increasing the bearing capacity of subgrade soils can reduce required base course or treatment thickness. Several design methodologies exists for the use of geosynthetics in subgrade restraint for pavement construction. This paper evaluates currently available design approaches and design tools including related proprietary software. Comparative analysis results for different design approaches are also presented in this paper.
