Origin of soils, formation of soils, clay mineralogy and soil structure, basic terminology and their relations, index properties of soils.
With the growing tendency to utilize marginal soils, there arises the need to understand the fundamental behavior of the materials in order to make suitable amendments in design parameters, especially in the subgrade construction of pavements.
The K factor is affected by many different soil properties and therefore quantifying the natural susceptibility of soils is difficult.

But in many cases available soils near construction sites are found to be weak in strength and of high compressibility, after routine compaction.
While the intensiﬁcation of agriculture between 1956 and 2007 has resulted in a general decrease of SOC stocks in Andalusia, soils like Arenosols have been largely affected by these transformations, in particular with changes from arable land to permanent crops.
D S V Prasad Abstract—Soils pose problems to civil engineers in general and to geotechnical engineers in particular.
2) Vibro-compaction Cohesionless Densification by vibration and a) Vibrofloat soils with less compaction of backfill material of b) Vibro-Composer than 20% fines.
Properties of vermicompost, farmyard manure and the soils of two locations Table 2b presents the physico-chemical characteristics of VC, FYM, and the soil.
2454-9290, Volume-3, Issue-5, May 2017 Characteristics of Clayey Soil Mixing With Randomly Distribute Plastic Waste Bags Arindam Saha, Joyanta Maity, Bikash Chandra Chattopadhyay Abstract— Due to large-scale constructional activities of roads in India, requirement of fill material is enormous and available soils near construction sites may be weak in strength and of high compressibility, even after proper compaction.
Requirement of fill material for large-scale constructional activities of roads, is enormous and available soils near construction sites are weak in strength and of high compressibility.

Nowadays, the best soils already have structures over them, but people still need to expand, which is why we have no choice but to build over soils even if they are not stable enough.
The global manufactured soils market growth is foreseen to be impeded by the low usage of manufactured soils due to lack of knowledge about the product.
