ABSTRACT:
A method for restructuring a railway roadbed by injecting therein an amount of structural slurry effective to form a substantially continuous structured layer which provides increased load carrying capacity to said roadbed, which substantially blocks the intrusion of water into the subgrade soil through the ballast section of said roadbed, and which limits the upward intrusion of subgrade soil into the ballast section.
