CONTRACTOR SAVES TIME AND MONEY WITH PLASTIC FABRIC ON RAIL RELOCATION JOB

Construction of a temporary track to carry the West Shore route over New York State Route 15 while a full grade separation is constructed has involved the use of plastic support and filter fabric in place of granular materials on the subgrade. The 6500-ft detour is on the same alignment as the old railroad drainage ditch. On the 3-ft graded sub-base layer, a 25-ft wide covering consisting of two rolls of the fabric with a 3-ft overlap has been installed. The plastic filter acts as a support membrane to improve the bearing capability of the soil underneath, preventing the mixing of the aggregate and subsoil while promoting drainage of both. The plastic is topped with a 12-in. layer of ballast to which a further 8-in. layer is added after the track is laid.
