Dynamic deflection modulus: Application conditions see Section 6; Para. 5
on soil formation: 1. Value for coarse-grained soils
2. Value for mixed and fine-grained soils
3)
This thickness assumes a hydraulically-bonded based course underneath the solid track of at least 30 cm
thickness
4)
Also coarse-grained soils GW, GI, SW and SI; see Module 836.0503, Section 3
5)
If the route is being overhauled for high-speed transport, new construction criteria apply
