This study examines consolidation of road services by local governments, and explores the optimal mix of roads for rural counties. A methodology for measuring economies in the provision of local road services is presented. This methodology is unique in two ways; 1) it better accounts for relevant variables...

The primary objective of this study was to investigate the effects of freeze-thaw conditioning and overloading on the resilient modulus (Mr) of subgrade soils susceptible to frost penetration. The Mr values of conditioned samples were compared to unconditioned samples. All Mr values were determined in...

This report describes a study to evaluate the use of subgrade resilient modulus for the design of flexible pavements. The objectives of this initial study were to: a) investigate the relationship between resilient modulus and R-value, and b) develop a predictive equation for resilient modulus based on...
