Reducing Lab Sample, Riffle Box, Quartering, Crusher Plant Sample to Lab Sample

This video is for the preparation of test portion/ sample from lab sample. For all testing in the lab, the lab sample quantity is more and we have to reduce the sample to the required size. Please watch the related presentation and sampling in the field videos in the following links

The following methods are used for test sample preparation
1. Sample Splitting Method
2. Quartering for Coarse aggregate
3. Quartering for fine aggregate
4. Miniature Stockpile Method for damp fine aggregate
