(2) Dynamic deflection modulus: For conditions of use see article 6; paragraph 5 for subgrade:
1. Value for coarse-grained soil
2. Value for mixed and fine-grained soil
(3) This thickness assumes a hydraulically bound base course of at least 30 cm under the solid track.
(4) as well as coarse-grained soils, gravels and sands with wide or intermittent grain size distribution; see modulus 836.0503, article 3
