TOWARD BETTER EVALUATION OF RAILROAD BALLAST AGGREGATE
The National Crushed Stone Association undertakes research aimed toward providing its producer members with authentic information on ways their products may be used to best advantage. One such investigation is attempting to develop simple laboratory methods of evaluating the quality of aggregate for use as railroad ballast. This current effort began in 1973, when Committee 1 of AREA sought information on the possible effect of changing the method of test for abrasion loss from ASTM Standard Method C 131 to Standard Method C535. Of the total of 34 samples included in this summary, 16 were tested in 1973 and 74, and the results reflect only the C 535 abrasion losses and some of the properties of the fines created. The complete program, including more extensive testing on 18 additional samples obtained in 1976 and 77 (all samples from sources known to have been supplying ballast to operating railroads) is described.
