Resilient Modulus Testing for Pavement Components

Nineteen peer-reviewed papers address the latest issues affecting the resilient modulus test and use of the test results. Resilient modulus indicates the stiffness of a soil under controlled confinement conditions and repeated loading. The test is intended to simulate the stress conditions that occur in the base and subgrade of a pavement system.

Papers cover:

• Repeatability of the test by testing replicated test specimens under 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 the resilient modulus of unsaturated and saturated cohesive soils

• Importance of the value of resilient modulus on required pavement thickness

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