Foltz, Randy B.; Truebe, Mark . 2004. Sediment Measurement from Multiple Aggregate Sources: Not All Aggregates Perform Identically. 0477 1308P. San Dimas, CA: U.S. Department of Agriculture, Forest Service, San Dimas Technology and Development Center. 3 p.

The Rocky Mountain Research Station and the Willamette National Forest performed a study to investigate the sediment production of several aggregates. Nine basalts, three quartzites, two welded tuffs, two alluvial, and one each of glacial outwash and limestone were tested. Each aggregate was used widely, had a maximum size of 25 mm, and was dense graded. Of the aggregates studied, 11 were good and 7 were of marginal (but still useable) quality, as originally identified by the design engineers.

Keywords: aggregates, multiple aggregate sources, sediment measurement
