All substances other than shell and all material passing the 75 micrometer sieve shall be considered foreign matter.ĭetermining the Quantity of Clam Shell in Clam and Reef Shell MixturesĮffective, this procedure is no longer applicable.Īmount of Material Finer than No. This method is designed to determine the percent by weight of foreign matter in clam shell, reef shell, and mixtures of clam and reef shell. This is to minimize the variations between the larger field sample and sample size needed for testing.ĭetermining the Amount of Foreign Matter in Clam Shell, Reef Shell, and Mixtures of Clam and Reef ShellĮffective, this procedure is no longer applicable. This procedure is intended for reducing of the gross sample to laboratory size using a mechanical splitting device.

CALCULATIONĦ.2 Calculate the density of the concrete using the following equation: These cores or pieces shall be of one layer of the PCC pavement and shall be free from observable cracks, fissures or shattered edges. TEST SPECIMENSĤ.1 The specimens shall be PCC cores or portions thereof.
The thickness of the test specimen can be equal to or less than the layer thickness.ġ.1 This test method covers the determinations of specific gravity, density, percent absorption and percent voids in PCC core specimens or portions thereof. Test Specimen: That part of the layer which is used for the specified test.The layer thickness can be equal to or less than the core thickness or length. The material within a particular layer is assumed to be homogeneous. Layer: That part of the pavement produced with similar material and placed with similar equipment and techniques.A core can consist of, or include, one, two or more different layers. Core: An intact cylindrical specimen of the pavement material that is removed from the pavement by drilling at the designated location.The following definitions will be used throughout this protocol: The test shall be performed on PCC cores or portions of PCC cores extracted from test sections included in the LTPP experiments. In all other sections, the standard (ASTM C642-97) shall be followed as written. Sections of the referenced standard which have been modified are included below. The test shall be conducted in accordance with ASTM C642-97 as modified herein. This protocol covers the determination of the specific gravity, density, percent absorption and percent voids in PCC.
