• Abstract:
  The Midwest States Accelerated Pavement Testing Pooled-Fund Program, financed by the highway ; departments of Kansas, Iowa, Missouri, and New York, has supported an accelerated pavement testing (APT) project ; to study the rehabilitation of low-volume paved roads with geocells and different infill materials under real-world ; traffic on a marginal subgrade, and to simulate this type of rehabilitation numerically so that a design method can be ; developed. To achieve this study objective, four pavement test sections were constructed at the Civil Infrastructure ; System Laboratory of Kansas State University. Three out of these four lanes had geocell-reinforced bases with three ; different infill materials: crushed limestone, quarry by-products, and Recycled Asphalt Pavement. The fourth test lane ; was the control section consisting of crushed stone base. All sections were heavily instrumented. Repeated loads (80- ; kN single axle) were applied using an accelerated pavement testing machine. The sections with 50-mm hot-mix asphalt ; (HMA) layer reached the failure criteria of 12.5-mm rut depth after 10,000 passes due to excessive stress in the ; subgrade. The redesigned sections with 100-mm HMA layer carried 1.2 million passes without reaching 12.5-mm ; failure rut depth. The geocells with marginal materials as infills appear to be viable in low-volume paved road ; applications.
