Book Description
The objectives of this research are to establish a resilient modulus test results database and to develop correlations for estimating the resilient modulus of Wisconsin fine-grained soils from basic soil properties. A laboratory testing program was conducted on representative Wisconsin fine-grained soils to evaluate their physical and compaction properties. The resilient modulus of the investigated soils was determined from the repeated load triaxial (RLT) test following the AASHTO T307 procedure. The laboratory testing program produced a high-quality and consistent test results database.

Book Description
This report describes a study jointly conducted by the University of Wyoming and the Wyoming Department of Transportation to examine the factors influencing the determination of a subgrade resilient modulus value. The objectives of this study were to first, investigate the importance of several fundamental soil properties in determining a design subgrade resilient modulus value; and second, to define the actual relationship between back calculated and laboratory based resilient modulus values for typical cohesive subgrade soils in Wyoming. This study consisted of selecting nine test sites with cohesive subgrade soils in the state of Wyoming, conducting laboratory testing on subgrade cores obtained in 1992 and 1993, determining several fundamental soil properties on these cores, and using deflection data from these nine sites to determine resilient modulus values from three back calculation programs. The data analysis resulted in several important conclusions about factors that influence the selection of a design subgrade resilient modulus value.

Book Description
The objective of this project was to determine the resilient moduli for common Missouri subgrade soils and typical unbound granular base materials in accordance with the AASHTO T 307 test method. The results allow Missouri Department of Transportation pavement engineers to calibrate software included with the National Cooperative Highway Research Program Project 1-37A Mechanistic-Empirical Pavement Design Guide according to Missouri's conditions and materials. The test results included resilient moduli data from 27 common subgrade soils out of the 99 Missouri soil associations and from five unbound granular base materials. The subgrade soils, selected and provided by MoDOT, were tested at their optimum water content (as determined from AASHTO T 99 testing (AASHTO, 2001)) and at an elevated water content. The five unbound granular base materials, again selected and provided by MoDOT and representing a typical range in geologic source, were tested at two different gradations (typical as-delivered percent minus #200 sieve size and at an elevated amount of fines). All testing included three replications for all materials. Data are provided in the form of tables and graphs. As a part of the granular base material resilient moduli (Mr) specimen preparation deliberation, MDD and OMC were determined for each of the 10 material/gradation combinations. The Mr testing program results indicate that both the material source and fines content are highly significant in the level of attained resilient modulus. In regard to material source, the range between the highest and lowest Mr values was more than two-fold. Also, two of the five aggregate sources suffered a 15 to 20% loss in Mr with the addition of five percent fines.
