1949 REPORT OF THE INVESTIGATION OF ROADBED STABILIZATION

The 1949 report of the investigation of roadbed stabilization is presented. Topics discussed include field studies and results of roadbed stabilization grouting, cost data, fill grouting and reports of the Illinois Central, Missouri-Kansas, Texas, Santa-Fe, Burlington, Great Northern and Northern Pacific Railroads. Conclusion reveals that the greater proportion of subgrade instability has been produced by surface water rather than underground flow. The correction of the instability depends on the diversion of this water before it reaches that portion of the subgrade where instability has developed. It is noted that grout promotes stability, and the degree to which grouting does put a roof over the subgrade appears to be a direct measure of the success of the stabilization. There is no evidence that grouting can prevent the development of these pockets. Other topics considered include tie and pole driving, piling, sand filled blast holes, and sand-filled spud holes. Relationships are studied between water content of material and its action under load. Tests reveal that loading apparatus is satisfactory and may operate with only minor maintenance.
