REPORT ON OPEN HEARTH SLAG FOR RAILROAD BALLAST
The test results on the open hearth slag as included in this report are for a sample furnished by the U.S. Steel Corporation from Lorain, Ohio. Although these results indicate that this material should prove satisfactory from the conductivity standpoint, it must be noted that this will not necessarily apply to open hearth slag material from other sources. We are of the opinion that open hearth slag can be processed to produce acceptable ballast material. However, control of the processing, particularly for the elimination of particles high in metallic content, is very important. In addition to the above tests a field inspection was made on a railroad in Michigan whose main line track is ballasted for a distance of approximately 90 miles with an open hearth slag ballast. The track has been in service with this ballast for a period of about five years without any difficulty being encountered with the signal system. The ballast is performing well in service having apparently resisted breakdown due to weathering and abrasion. Inspections of this nature are planned on other railroads using open hearth slag ballast with samples being taken for laboratory tests.
