SUBGRADE RESILIENT MODULUS FOR IDAHO PAVEMENTS. FINAL REPORT

This report documents a method for estimating seasonal values of resilient moduli of subgrade soils and proposed for use with the 1986 AASHTO flexible pavement design guide. The method consists of applying a series of adjustment coefficients to a "reference resilient modulus", defined as the most probable resilient modulus measured on a soil compacted to 100% of the AASHTO T-99 maximum dry weight at optimum water content with a bulk stress of 10 psi. Reference resilient moduli are provided from a literature review for twelve soil classes as a function of grain sizes and soil plasticity.
