Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: Resilient modulus test is the recommended test to characterize subgrade soil for pavement design in 1993 AASHTO pavement design guide as well as new proposed Mechanistic-Empirical Pavement Design Guide (MEPDG). This test requires significant resources including high level of technical capability to conduct. For smaller projects where costly and complex resilient modulus testing is not justified, correlation with other simpler tests could be used. Virginia Department of Transportation uses a simple correlation with California Bearing Ratio (CBR) to estimate resilient modulus for their current AASHTO design. As the correlation with CBR was found to be poor; a simpler unconfined compression test is explored for a better estimation of resilient modulus of fine grained soils. A model is proposed to estimate the resilient modulus of fine grained soil from the results of unconfined compression test.
