Soft formations underlying roadbed layed on marsh ground fill were treated by excavation and backfilled with quarry waste. Followed consolidation of the material, ballast was spread and tamped, and the track replaced. Another method utilized precast concrete slabs emplaced between a 12 in. blacket of quarry waste and the ballast. Additional details are given on the two methods as employed at specific sites, and include information on the typical "soft formation" conditions encountered and test procedures prior to rebuilding the roadbeds.
