• Abstract:
  This report covers the Fiscal Year 2002 project conducted at the Accelerated Testing Laboratory at Kansas ; State University. The project was selected and funded by the Midwest Accelerated Testing Pooled Fund Program , ; which includes Iowa, Kansas, Missouri and Nebraska. ; The objective of this research was to determine the effectiveness of the use of foamed asphalt stabilized ; Recycled Asphalt Pavement from full-depth reclamation (FAS-FDR) as base material for flexible pavements. The ; experiment, conducted at the Accelerated Testing Laboratory (ATL) of Kansas State University, consisted of ; constructing four pavements, one with a nine inch conventional Kansas AB-3 granular base and three with six, nine ; and 12 inches of FAS-FDR, and subjecting them to full-scale accelerated pavement test. All four pavements sections ; were loaded with 500,000 ATL load repetitions, at room temperature and under moderate moisture levels in the ; subgrade soil. The measured stresses and strains as well as the permanent deformation (rutting) observed on the ; pavement sections indicated that FAS-FDR can be successfully used as a base material. The measured rut depths and ; compressive vertical stresses at the top of the subgrade suggest that one inch of FAS-FDR base shows performance ; equivalent to that of one-inch conventional Kansas AB-3 granular base. The effective structural number computed ; from the FWD deflection tests on the as-constructed pavements showed that average structural layer coefficient for the ; FAS-FDR base material is 0.18.
