THE PRECISION OF SELECTED AGGREGATE TEST METHODS

The interlaboratory correlation program pilot study is briefly discussed. Precision statements derived from the study are presented for the following test method: sieve analysis, percent crushed particles, L.A. rattler, sand equivalent, cleanness value, durability index, and R-value. Relative amounts of general error types such as between operator and between laboratory are given for each test method, and possible causes are discussed. Laboratory performance is shown through the use of scatter diagrams and ranking summaries. Recommendations for improving test precision are given.
