To evaluate the strength of the aggregate in order to give a clear overview about the tested material.
YGP stands for Yancey, Geer, and Price and is one of the methods used to determine the abrasion index of a material. It is a test that measures the abrasiveness and wear resistance of a material by subjecting it to wear and measuring the resulting abrasion index.
The three forms of abrasion are mechanical abrasion, chemical abrasion, and physical abrasion. Mechanical abrasion involves the physical wearing away of a material by friction or impact. Chemical abrasion occurs when a material is worn down through chemical reactions, such as oxidation. Physical abrasion is the erosion of a material due to external forces like wind or water.
Abrasion is often likened to a sandpaper effect acting on the rock in question. Abrasion occurs when an agent of erosion carries sediment and the sediment collides with a rock face, breaking both up.
Any form of abrasion is a physical process.
The process of weathering caused by solid particles hitting or rubbing against rocks is called abrasion. This physical process can gradually wear down the surface of rocks over time, leading to erosion and a change in their appearance.

Abrasion resistance is typically measured using standardized tests such as the Taber Abrasion Test or the Martindale Abrasion Test. These tests involve subjecting the material to repeated rubbing or abrasion under controlled conditions to simulate wear and tear. The resistance of the material to abrasion is then quantified by measuring the loss in weight or thickness of the material after a specified number of abrasion cycles.

proper test planning
abrasion resistance is the resistance in abrasion
ASTM D 123 describes as followsAbrasion, n---the wearing away of any part of a material by rubbing against another surface.ASTM also has prescribed several methods to quantify abrasion resistance of textile materials these tests areASTM D 4966 -- 98 Standard Test Method for Abrasion Resistance of Textile Fabrics (Martindale Abrasion Tester Method)ASTM D 3884 Test Method for Abrasion Resistance of Textile Fabrics (Rotary Platform, Double-Head Method)3ASTM D 3885 Test Method for Abrasion Resistance of Textile Fabrics (Flexing and Abrasion Method)3ASTM D 3886 Test Method for Abrasion Resistance of Textile Fabrics (Inflated Diaphragm Method)3ASTM D 4157 Test Method for Abrasion Resistance of Textile Fabrics (Oscillatory Cylinder Method)3ASTM D 4158 Test Method for Abrasion Resistance of Textile Fabrics (Uniform Abrasion Method)3AATCC Test Method 93 Abrasion Resistance of Fabrics: Accelerator Method4In All of the above materials the tested specimen is rubbed is a particular manner against an abradent which may be a fabric, or a emery sheet or like for either a certain amount of time for for a certain number of strokes or cycles.At the end of the testing period , any change that may occur to the tested specimen normally 3 types of changes are looked for1. Mass Loss2. Color Change3. Hole formation or yarn breakageThe Earlier these changes occur the poorer the resistance to abrasion.Factors loke thickness of fabric, piles, any pretreatment to reduce or increace surface friction , etc all have a profound effect on the Abrasion resistance.In real life, trousers in case of apparel and Upholstery are subject to more abrasion than fabrics used in any other domestic use. In case of fabrics used for industrial application like belts etc are required to have very high abrasion resistance.ReferencesASTM International Book of Standards Volume 7.01 and 7.02AATCC Technical Manual - 2009
The importance of slump test in concrete work is to ensure consistency in the concrete. The test measures the workability of the concrete.

The unit of abrasion resistance is typically measured in terms of cycles, such as the number of cycles until the material shows signs of wear or damage. Another common unit is the Martindale test, which measures abrasion resistance in terms of the number of rubs before wear is visible.
