AASHTO stands for American Association of State Highway and Transportation Officials. Today in this post I am going to share with you AASHTO Soil Classification Excel Spread sheet in .xlsx format. Developed in 1992 a comprehensive soil classification system that ...

If the concentration of harmful salts in the root zone of a plant increases to such an extent that plant growth is effected, this situation is called Salinity. Salinity is the measure of all the salts dissolved in water. Salinity ...

You might have been to a beach or near a river bank, have you ever noticed the cohesion-less sands there? I am currently working in a project which is in a mountain range with river crossing through and is actually ...

You might have heard a lot in geotechnical engineering lectures about Atterberg limits but today I have brought to you a very unique and useful importation about Atterberg Limits which you might not even know.  Albert Mauritz Atterberg was a ...

When the soil is added with water enough to make it paste like material it is termed as plastic state; in this state the soil can be molded into any shape without breaking and thus called plastic. If more water ...

Have you ever visited a beach? Played with sand castles? If yes than you are lucky enough to physically use one of a very vital and important characteristic of soil which is termed as plasticity. Soil when added or applied ...

The ingredients of soil cement, as already mentioned in our earlier post about soil cement, are cement, soil and water. Each ingredients must have some suitable properties other wise alternatives can be used in order to avoid any problem in ...

Soil mechanics and foundation engineering (geotechnical engineering) is a fast developing discipline of civil engineering. Considerable work has been done in the field in the last 6 decades. A student finds it difficult to have access to the latest literature ...

Soil mechanics originated several decades ago under the pressure of necessity. As the practical problems involving soils broadened in scope, the inadequacy of the scientific tools available for coping with them became increasingly apparent. Efforts to remedy the situation started ...

The Structural loads are supported on soil through foundations. These loads produce stresses and resulting strains or deformations in the soil below the foundation. The deformation in the vertical direction is usually termed as settlement, which occurs due to the ...
