Samenvatting
The new Mechanistic Empirical Pavement Design Guide (MEPDG) and other existing pavement design guides use resilient modulus (MR) as the primary input parameter when characterizing stiffness of subsoils and unbound bases. Resilient modulus of soils is typically determined either by using laboratory tests or field tests. This report was prepared to describe the significance of the resilient modulus property, various methods of determining this property of subsoils and unbound bases, and the application of this parameter in the mechanistic empirical pavement design guide. The report will be of interest to design, geotechnical and materials engineers and technicians. (Author/publisher)
