N2 - Geosynthetics have been widely used as construction materials for soil reinforcement since 1970s. In the past, most of the research on subgrade improvement and base reinforcement has been focused on planar geosynthtics, such as geogrid and woven geotextile. However, limited research has been done on three-dimensional geocell reinforcement of base courses. A series of static and cyclic plate loading tests, full-scale moving wheel tests, and numerical modeling were conducted by the research team at the University of Kansas on geocell-reinforced base courses with different infill materials (Kansas River sand, quarry waste, well-graded aggregate, and recycled asphalt pavement). This paper summarizes the main research findings from these studies addressing permanent, elastic, and creep deformations, stiffness, bearing capacity, and stress distribution, development of design methods for geocell-reinforced bases. These studies showed that geocell-reinforced base courses reduced the vertical stresses at the interface between subgrade and base course, reduced permanent and creep deformations, increased elastic deformation, stiffness, and bearing capacity of base courses.
