... for stabilizing the railway where this crosses Newham Bog between Morpeth and Berwick. This novel approach, using geotextiles and plastics, enabled the line speed over the peat bog to be raised from 125 km/h (80 mph) to 160 km/h (l00 mph) cost-effectively, to the satisfaction of the client, InterCity. © Thomas...

...T. S. Ingold, BSc, MSc, PhD, DIC, MConsE, FICE, FASCE, FIHT, FGS, MSocIS Geotextiles are credited with the ability to filter, drain, separate and reinforce soil. These functions can be performed in isolation or in concert depending upon the requirements of the designer. A case history is presented...

...P. J. Whyley, BSc, CGeol, MICE, FGS In any branch of engineering, consideration of construction methods is an essential part of the design process. This is particularly true for designs which incorporate geotextiles. There are many factors influencing fabric survivability including construction...

...P. R. Rankilor, BSc, MSc, FICE, FTI, FIGeol, FIMM, FGS The largest use of geotextiles in civil engineering, in terms of the total area of material used, is for separation. Yet it is one of the most difficult of geotextile functions to define and describe. This set of technical notes was prepared...

...N. W. M. John, BSc, PhD, MICE, FGS, MIHT The purpose of a geotextile separator beneath a granular sub-baisse to prevent the road aggregate and the underlying subgrade soil from intermixing. In the absence of a geotextile, contamination of the sub-base aggregate by soft subgrade soil could reduce...
