Ministry of Transportation, Ontario Test Method LS-607, Rev. No. 27 Laboratory Testing Manual Date: 12 04 01 Page 1 of 8 METHOD OF TEST FOR DETERMINATION OF PERCENT CRUSHED PARTICLES IN PROCESSED COARSE AGGREGATE 1.
1. Calculate the percent of crushed particles in each respective test sample using the following formula: x 100 Test Sample Weight Weight of Crushed Particles Percent of Crushed Particles Table 2 is an example illustrating a typical calculation.
Crushed Particles) / (Test Sample Weight)] × 100 2. Calculate the percent of crushed particles in the whole or in the coarse portion of the as-received sample by the weighted average method as follows: Multiply the percent of each size fraction to be included in
1.1 This method covers the visual determination of the percent, by mass, of particles with two or more crushed faces and percent, by mass of uncrushed particles in a processed coarse aggregate. 1.2 The anticipated purpose of this test procedure is to assist in identifying those sources of
of Crushed Particles in Aggregate 1. Scope 1.1 This test method covers the determination by visual inspection of the percentage of crushed particles (by mass) that are present in a sample of aggregate. 1.2 The values stated in SI units are to be regarded as the
1. Calculate the percentage of crushed particles as follows: F Percent Crushed Particles (P) = ----- x 100 F + N Where: F = Weight of crushed particles with at least the specified number of fractured faces, in grams N = Weight of uncrushed F = 730
CRD-C171-94 Standard Test Method for Determining Percentage of Crushed Particles in Aggregate Date: 06-01-1995 This test method covers the determination by visual inspection of the percentage of crushed particles (by mass) that are present in a sample of 2
1/5/2003 A. Calculate the percentage of crushed particles for each separate fraction as follows: Percent Crushed Particles (CP) = C A (B/2) X 100 Where: A = Weight of crushed particles with at least the specified number of fractured faces, in grams.
Total Percent Crushed Particles = (% Crushed Particles 3/4 to 3/8 in. [19.0 9.5 mm]) x (% of 3/4 to 3/8 in. [19.0 9.5 mm] Material) + (% Crushed particles 3/8 in. No.4 [9.5 4.75 mm]) x (% of 3/8 in. No. 4 [9.5 4.75 mm] Material) Using the following
This method of test is for the determination of the percent of crushed particles in coarse aggregate. 2. Definitions and Standards 2.1. A fully fractured face is defined as an angular, rough or broken surface of an aggregate particle created by crushing, by other
