Proctor Compaction Test: A Basic Guide, When performing a field density test, the dry unit weight is compared to the maximum dry weight of the Proctor tests to calculate a percent of compaction When the required densities are hard to reach in the field, the moisture content should be compared to the optimum moisture content from the lab tests If field moistures differ more than 2% ,ASTM D1241, 11 This specification covers the quality and grading of the following materials for use in the construction of subbase, base, and surface courses: sand-clay mixtures; gravel; stone or slag screenings; sand; crusher-run coarse aggregate consisting of gravel, crushed stone, or slag combined with soil mortar; or any combination of these materials The requirements are intended to cover ,Field Density Test of Soil by Sand Replacement Method, The field density test of soil is conducted in the field to know whether the specified compaction is achieved or not Normally Sand Replacement Method is adopted for this purpose Sand Replacement Method is also known as Sand Cone Method The apparatus used in this field density test consists of a sand pouring cylinder, with pouring cone at its ,Soil Compaction Tests, One of the most common test to determine the field density of soil is the sand-cone method But it has a major limitation that this test is not suitable for saturated and soft soils The formula used are Volume of soil, ft 3 (m 3)=[weight of sand filling hole, lb (kg)] /[ Density of sand, lb/ft 3 (kg/m 3)]TEST METHOD FOR EARTHWORK COMPACTION ,, To evaluate the field density, it is must be compared to a control density The control density is expressed in terms of the dry density of the minus ¾ in (19 mm) portion of the material The method of determining the control density is described in Section 52 The field density, Line H, is in total wet density ,.
The frequency of Various tests, Sep 02, 2014· In the first stage of construction the first test shall be taken is the In-Situ Density test but I was a bit stock when the consultant asked about the frequency of compaction test of in-situ soil I made a research immediately just within the contract project documents: specification, drawing, bill of quantity but most often it is written on the specification, sometimes it is also written in ,Significance of "one, May 19, 2003· Sounds like the on-site soils are getting more compactive energy causing the field dry densities to be higher than the ASTM D 698 (Standard "Proctor") lab optimum dry density Or your material has changed Running single points in the field is done to check for changes in the materialIA DEPARTMENT OF TRANSPORTATION SOILS AND ,, Field Moisture and Density Testing with the Nuclear Gauge Break for Lunch : Chapter 6: , off-site sources (Borrow Excavation), crushed aggregate (Crusher Run, Dense Graded Aggregates for roadway base and subbase), or blended natural and crushed aggregates , several tests are run Each test gives information about the soil, and how it will ,Material Coverage & Conversion Chart, Crusher Fines 18 Compacted 15 Loose Infield Mix 175 Compacted 125 Loose Rip Rap 165 Class 6 Base 1 75 compacted Square feet to Cubic Yard conversion L x W = Sq Ft Inches deep ÷ 12 = Depth L x W x D ÷ 27 = CY Mulches and Bark One CY Covers 160 Sq Ft 2" Deepmawar khayalan: Method Statement, Dec 07, 2013· 656 Field Density Test (FDT) or CBR , 661 The crusher run road base to be placed on top of the sub base shall consisting of crushed aggregate laid in layers each of thickness not exceeding 200mm and to give the specified total compacted thickness and width, ,.
Soil Compaction Handbook, Proctor Test (ASTM D1557-91) The Proctor, or Modified Proctor Test, determines the maximum density of a soil needed for a specific job site The test first determines the maximum density achievable for the materials and uses this figure as a reference Secondly, it tests the effects of moisture on soil density The soil reference value is ,DENSITY STANDARDS FOR FIELD COMPACTION OF ,, the ASTM Method D 2049 (Relative Density), the Washington Spring-Loaded Vibratory Compactor Method, the Marshall Hammer Test, and the Gyratory Compactor Procedure The aggregates tested were a granite-gneiss, a crushed gravel, a dolomitic limestone, and a basalt A prototype field compaction 'testing program was conducted using the sameMethod of Statement, Dec 09, 2015· Step 3 Carry out joint inspection with Subcontractor on the sub-base level PREPARATION OF ROAD BASE Step 1 Lay crusher run on top of sub-base and compact by the roller The thickness for any layer is according to specification Step 2 Carry out field density test and CBR test on the road base as per specification if required 3NUCLEAR DENSITY TEST, EXECUTION OF TESTING IN FIELDSoil Testing Equipment, Soil Density Testing, Humboldt provides a complete line of soil testing products for field applications These items include nuclear gauges and the electrical density gauge for soil compaction Humboldt also provides plate load testers, shelby tubes, lightweight deflectometers and a large offering of penetrometers for all applications.
