Cracked slab analysis for paved concrete track sensitivity to formation stiffness (IM-PACT-043)

Internal Memorandum IMPACT 37 discussed the affects of varying the elastic parameters of the cracked slab model described in Internal Memorandum IMPACT 28. The rail vertical EI, rail pad stiffness and slab vertical EI are normally predictable and vary little, if at all, at any particular installation. The big unknown...
