HAL Substructure Investigation Using Rapid, Non-Destructive Techniques
As part of a program to determine the nature of track substructure problems and to recommend the best remedial action, the Association of American Railroads has developed an on-track vehicle which houses a rapid, non-destructive subgrade test apparatus known as a cone penetrometer. Although still...FAST Heavy Axle Load Program Safety Compendium
