LTPP Protocol P46: Resilient Modulus of Unbound Granular Base/Subbase Materials and Subgrade Soils |
Primary Topic: Materials-Unbound and Soils
Description: This LTPP program protocol describes the laboratory preparation and testing procedures for the determination of the Resilient Modulus (Mr) 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 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.
