Standard Test Method for Density of Soil and Rock in Place by the Water Replacement Method in a Test Pit
SIGNIFICANCE AND USE
This test method is used to determine the in-place unit weight of compacted materials in construction of earth embankments, road fills, and structure backfill. For construction control, it can be used as the basis for acceptance of material compacted to a specified unit weight or to a percentage of a maximum unit weight determined by a standard laboratory test method such as determined from Test Methods D 698 or D 1557, subject to the limitations discussed in 1.4.
This test method can be used to determine in-place unit weight of natural soil deposits, aggregates, soil mixtures, or other similar material.
SCOPE
1.1 This test method covers the determination of the in-place density and unit weight of soil and rock using water to fill a lined test pit to determine the volume of the test pit. The use of the word "rock" in this test method is used to imply that the material being tested will typically contain particles larger than 3 in. (75 mm).
1.2 This test method is best suited for test pits with a volume between approximately 3 and 100 ft3 (0.08 and 2.83 m 3). In general, the materials tested would have maximum particle sizes over 5 in. (125 mm). This test method may be used for larger sized excavations if desirable.
1.2.1 This procedure is usually performed using circular metal templates with inside diameters of 3 ft (0.9 m) or more. Other shapes or materials may be used providing they meet the requirements of this test method and the guidelines given in for the minimum volume of the test pit.
1.2.2 Test Method D 4914 may be used as an alternative method. Its use, however, is usually only practical for volume determination of test pits between approximately 1 and 6 ft 3 (0.03 and 0.17 m3).
1.2.3 Test Method D 1556 or Test Method D 2167 is usually used to determine the volume of test holes smaller than 1 ft3 (0.03 m3).
1.3 The two procedures are described as follows:
1.3.1 Procedure AIn-Place Density and Unit Weight of Total Material (Section ).
1.3.2 Procedure BIn-Place Density and Unit Weight of Control Fraction (Section 10).
1.4 Selection of Procedure
1.4.1 Procedure A is used when the in-place unit weight of total material is to be determined. Procedure A can also be used to determine percent compaction or percent relative density when the maximum particle size present in the in-place material being tested does not exceed the maximum particle size allowed in the laboratory compaction test (Test Methods D 698, D 1557, D 4253, D 4254, D 4564). For Test Methods D 698 and D 1557 only, the unit weight determined in the laboratory compaction test may be corrected for larger particle sizes in accordance with, and subject to the limitations of, Practice D 4718.
1.4.2 Procedure B is used when percent compaction or percent relative density is to be determined and the in-place material contains particles larger than the maximum particle size allowed in the laboratory compaction test or when Practice D 4718 is not applicable for the laboratory compaction test. Then the material is considered to consist of two fractions, or portions. The material from the in-place unit weight test is physically divided into a control fraction and an oversize fraction based on a designated sieve size. The unit weight of the control fraction is calculated and compared with the unit weight(s) established by the laboratory compaction test(s).
Because of possible lower densities created when there is particle interference (see Practice D 4718), the percent compaction of the control fraction should not be assumed to represent the percent compaction of the total material in the field.
1.4.3 Normally, the control fraction is the minus No. 4 sieve size material for cohesive or nonfree-draining materials and the minus 3-in. sieve size material for cohesionless, free-draining materials. While other sizes are used for the control fraction (3/ 8, 3/4-in.), this test method has been prepared using only the No. 4 and...
