Jun 29, 2018· Core Cutter Method of Field Density test is conducted in the field to know whether the specified compaction is achieved or not.. In certain cases, it is necessary to determine the density of soil either as it exists naturally in the ground or as it may be compacted in the fill.. In the former case, this density of soil in place may be used to estimate the comparative strength of the soil.

Chapter 6 Standard Test Procedures Determination of In-situ Density MAY 2001 Page 6.10 6.3 Core Cutter Method 6.3.1 Introduction. This method is only used on fine-grained cohesive soils which do not contain stones. It is, therefore, very useful for control of earths and subgrade materials but is not suitable for coarse grained pavement

Mar 31, 2009· 3) Form embankment with suitable cross Field Density Test shall be done fall to avoid water ponding. While if the using Sand Replacement Method (in surface is too dry, provide water tanker accordance with BS1377: Part 2) or to control the moisture.
Authorities. The Drive Tube Method and Nuclear Method are the most time efficient tests and are widely used by several testing agencies. Once the field compaction is determined, a plot of the field moisture density compaction test is then compared to the proctor compaction curve. Using the following formula the Relative compaction can be
Apr 02, 2014· Aim To determine the field density of soil at a given location by sand replacement method Reference IS-2720-Part-28-Determination of dry density of soils in place, by the sand replacement method Apparatus Sand pouring cylinder Calibrating can Metal tray with a central hole Dry sand (passing through 600 micron sieve) Balance Moisture content bins Glass plate
The dry density test is done using one of three methods: sand replacement, core cutter, or water displacement. Of these, the sand replacement and core cutter methods are the more widely used. Atterberg Limits Test. This test is done on the fine-grained soil to measure its critical water content.
This test is done to determine the in-situ dry density of soil by sand replacement method as per IS: 2720 (Part XXVIII) 1974. The apparatus needed is A sample proforma for the record of the test results is given below. More Entries : Determine The In-Situ Dry Density Of Soil By Core Cutter Method;
Jun 22, 2015· field density test and a field moisture content test on the lift. The results of these field tests are compared to the target values (see Chapter 5) to determine if the con has met specifications for density and moisture material to be tested, there are different testing methods that can be used to obtain the data. One method is used
taking cores from the roadway to determine density, and to determine the locations for securing core samples for testing. The mixtures and core samples obtained from this procedure will be used for acceptance or rejection in accordance with applicable specifications. All sampling shall be Global Positioning System (GPS) located and noted.
2 Test No.: Tests for a project shall be numbered as required by MURK. 3 Station of Test: The location of the test should be determined accurately. 4 Offset: The location of the test should be determined accurately. 5 Location: The required percent of maximum density
