2. Plate loading method. Similar to the plate load test described in Sec. 7.3.2, the rock could be
subjected to a plate loading test in order to determine the load-deformation behavior of the rock. For
further details, see ASTM D 4394-98 (2004), “Standard Test Method for Determining the In Situ
Modulus of Deformation of Rock Mass Using the Rigid Plate Loading Method” and ASTM D 4395-98 (2004), “Standard Test Method for Determining the In Situ Modulus of Deformation of Rock
Mass Using the Flexible Plate Loading Method.”
