Abstract:

This Long-Term Pavement Program (LTPP) program protocol describes the laboratory preparation and testing procedures for the determination of the Resilient Modulus (M r) of unbound granular base and subbase materials and subgrade soils under specified conditions representing stress states beneath flexible and rigid pavements subjected to moving wheel loads. This protocol is based partially on the test standard American Association of State Highway and Transportation Officials (AASHTO) T292-91I, Resilient Modulus of Subgrade Soils and Untreated Base/Subbase Materials. The test shall be carried out in accordance with the following protocol procedure.
