Nineteen peer-reviewed papers address the latest issuesaffecting the resilient modulus test and use of the test results.Resilient modulus indicates the stiffness of a soil undercontrolled confinement conditions and repeated loading. The test isintended to simulate the stress conditions that occur in the baseand subgrade of a pavement system.

Papers cover:

• Repeatability of the test by testing replicated test specimensunder the same conditions.

• Background of test startup and QC procedures

• Review of the LTPP test program

• Effect of water content and pore water pressure buildup on theresilient modulus of unsaturated and saturated cohesive soils

• Importance of the value of resilient modulus on requiredpavement thickness

This book is a valuable resource for highway engineers,geotechnical engineers, laboratory personnel who conduct pavementtests, pavement designers, and foundation engineers.
