SAMPLING METHODS IN SOCIAL RESEARCH Muzammil Haque Ph.D Scholar Visva Bharati, Santiniketan,West Bangal Sampling may be defined as the selection of some part of an aggregate or totality on the basis of which a judgement or inference about the aggregate or totality is made. In
METHODS OF SAMPLING Due to the various sampling loions and the availability of equipment, there are several methods of taking aggregate samples. Uniformity of obtaining the sample cannot be emphasized enough, since it eliminates one variable in test results. The technician must remember that safety comes first. PRODUCTION SAMPLING Bin Sample
SIEVE ANALYSIS AND FINENESS MODULUS Sampling Since the reason for sampling aggregates is to determine the gradation (particle size) of the aggregate, it is necessary that they be sampled correctly. The results of testing will re" ect the condition and characteristics of the aggregate
8.1 Road sampling is carried out after the aggregates have been placed and spread, but prior to watering, grading, or compaction. Either the random time method or the random quantity method may be used to select the portion of aggregate to be sampled. In the case of random time, the
A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.

SAMPLING AGGREGATE PRODUCTS FOP FOR AASHTO R 90 . Scope . This procedure covers sampling of coarse, fine, or a combination of coarse and fine Method C – Alternate Tube Method (Fine Aggregate) 1. Remove the outer layer that may have become segregated. 2. Using a sampling tube, obtain one increment of equal size from a minimum of five
Durability and Abrasion equipment measures the hardness, strength and durability properties of aggregates. Sulfate Soundness, Los Angeles Abrasion Machine and MicroDeval tests are some of the popular methods used to analyze properties such as resistance to wear, susceptibility to freezethaw damage and overall aggregate strength.
aggregate or a stockpile of combined coarse and ﬁne aggregate, design a sampling plan for the speciﬁc case under consideration. This approach will allow the sampling agency to use a sampling plan that will give a conﬁdence in results obtained therefrom that is agreed upon by all parties concerned to be acceptable for the particular
