standard value of compaction factor

Compaction of Soil – Process, Necessity and .AASHO developed a modified test to give a higher standard of compaction and is known as modified proctor test. The same is also known as heavy compaction test as per BIS. Standard Proctor Test (or Light Compaction Test): The apparatus consists of a cylindrical metal mould of internal diameter 100 mm, 127.3 mm height and 1000 c.c. volume. The rammer used for this test is 2.6 kg mass, 310 mm ...DENSITY STANDARDS FOR FIELD COMPACTION OF GRANULAR .NCHRP Project 4-8(2), "Density Standards for Field Compaction of Granular 'Bases and Subbases," was selected--from among 'these studies and work was started in April 1971 by Clemson University. The objective of this project was to evaluate current procedures and criteria for the setting of density standards to control compaction during construction of granular base and subbase courses, and to ...Compaction Factor Test - LinkedIn SlideShareCompaction Factor Test • It is more accurate than slump test for concrete mixes and value of compaction factor of 0.75 to 0.8 is suggested as per IS . • It is not suitable for concrete of very low workability of 0.7 or below. 6. Compaction Factor Appartus 7. Compaction Factor Test Procedure • The concrete sample is placed in the ...Exp 8 Compacting Factor - Civil Engineers PKThe value of compactness factor tells us that the workability of concrete is Low but the slump value tells us that the workability is Medium. This variation was due to the reason that when the first test was performed the then apparatus was not made wet which made the reading slightly more. The sensitivity of the compaction factor is reduced outside the normal range of workability and is ...

How To Calculate A Compaction Test Report

27.12.2014· This is a continuation of the previous article I posted How to do a compaction test or In-situ density test, about the calculation of the compaction test report. Here we are going to compute the bulk density of sand down to the degree of compaction of soil.. I would really want to pursue this article just to completely show the full process of getting the results of the test from taking the ...Compaction - University of the West of EnglandCompaction is a process that brings about an increase in soil density or unit weight, accompanied by a decrease in air volume.There is usually no change in water content.The degree of compaction is measured by dry unit weight and depends on the water content and compactive effort (weight of hammer, number of impacts, weight of roller, number of passes).How to Calculate the Soil Compaction Factor | .How to Calculate the Soil Compaction Factor By Jack Burton ...

Ans:- The precaution that has to be taken are:-(i) Accurate amount of water, cement and sand are to be taken to avoid collapsing of sample. (ii) Maintain the consistency throughout ...Proctor compaction test - WikipediaThe Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density. The test is named in honor of Ralph Roscoe Proctor, who in 1933 showed that the dry density of a soil for a given compactive effort depends on the amount of water the soil contains during soil ...How to Calculate the Soil Compaction Factor | .How to Calculate the Soil Compaction Factor By Jack Burton ...

Compaction Factor Test is designed in such a way that it can be used only in laboratory but in some cases, it can be used for field concrete tests. The compacting factor test has been developed at the Road Research Laboratory in United Kingdom.Concrete Slump and Compacting Factor Test .15.02.2016· The slump and compacting factor test values shown below are of concretes with 20mm or 40mm maximum size of aggregates. Degree of workability. Slump (mm) Compacting factor. Use for which concrete is suitable. Small apparatus. Large apparatus. Very low – 0.78. 0.80. Roads vibrated by power-operated machines. At the more workable end of this group, concrete may be compacted in .Factors affecting Soil Compaction | Water .Factors Affecting Soil Compaction. Following are the factors affecting Soil Compaction: Water content of the soil at the time of compaction. The amount of compactive energy used e.g. type of plant (weight, vibration, number of passes) Nature and the type of soil being compacted like sand or clay, grading, plasticity; Site conditions, e.g. weather, type of site, layer thickness; Effects of ...Fundamentals of Soil Compaction3.2 Factors affecting Compaction • Water content of the soil • The type of soil being compacted • The amount of compactive energy used 3.3 Laboratory Compaction tests There are several types of test which can be used to study the compactive properties of soils. Because of the importance of compaction in most earth works standard procedures have been developed. These generally involve ...Compaction - Pavement InteractiveA control strip is a short pavement section that is compacted to the desired value under close scrutiny then used as the compaction standard for a particular job. Pavement air voids are measured in the field by one of two principal methods: Cores (Figures 2 and 3). A small pavement core is extracted from the compacted HMA and sent to a laboratory to determine its density. Usually, core density ...ESTIMATING EARTHWORKSwell (%) = ( - 1) x 100 Load factor = Bank Volume = Loose volume x Load factor Shrinkage: A soil decreases in volume when it is compacted Shrinkage (%) = (1 - ) x 100 Shrinkage factor = 1 - Shrinkage Compacted volume = Bank volume x Shrinkage factor Approximate Material Characteristics Exact values will vary with grain size, moisture content, compaction, etc. Test to determine exact values ...
