HOW TO CHECK QUALITY OF SAND IN FIELD?

 · Field Test on Sand. Take a glass of water and add some quantity of sand in it. Then shake it vigorously and allow it to settle. If clay is present in sand, it will form a distinct layer at the top of sand. In order to detect presence of organic impurities in sand, add sand to the solution of sodium hydroxide or caustic soda and then stir it.

The AASHTO Classification System | Civil Engineering

The AASHTO system classifies soils into seven primary groups, named A-1 through A-7, based on their relative expected quality for road embankments, subgrades, subbases, and bases. Some of the groups are in turn divided into subgroups, such as A-1-a and A-1-b. Furthermore, a group index may be calculated to quantify a soil''s expected ...
