Tips for Better Compaction
Each soil type has unique characteristics, from absorbency to compaction difficulty. The moisture content in the soil also must be considered before starting to do compaction work. There is a happy medium in terms of soil moisture—too much moisture weakens stability, but too little moisture will result in poor compaction.

Subbase materials preferably might consist of naturally occurring, coarse-grained soils or blended and processed soils. When possible, avoid using materials which have more than 15 percent fines. Lift thickness is dependent on the type of material, the compaction equipment used, and the method of construction.
Types of Soil Tests For Road Construction | PDF | Soil
Compaction test – Proctor test. This soil compaction test also called as Proctor test is used for the determination of the mass of. dry soil per cubic metre when the soil is compacted over a range of moisture contents, giving. the maximum dry density at optimum moisture content. Thus this test provides the compaction.

Types of Soil – Sand, Silt, Clay & Loam
A loam is a soil that has 30% clay, 50% sand, and 20% silt. This soil is dry, has a dark appearance, and crumbled when touched. Nutrient supply to the roots is enhanced by the airspaces that separate the particles. In comparison to sandy soils, loam soils often have higher levels of nutrients, moisture, and humus.
The Nitty-Gritty of Soils in Roadway Design
What is dirt made of? Snakes and snails and puppy dog's tails? Well, hopefully not, at least in road construction, because all of that stuff is organic material. While organic matter may be mixed in with soil, particularly in fine-grained soils, it is generally undesirable in any part of a roadway structure. Highly organic …
Soil Stabilization Methods
Soil stabilization is a method of improving soil properties by adding and mixing other materials to it. Soil stabilization is a method of enhancing the shear strength parameters of soil and thus increasing the bearing capacity of the soil. It is generally required when the soil under the foundation for construction is not suitable to carry the structural load.
