What Is Uniformly Graded Soil?
Uniformly Graded. When All the Particles Present in the Soil Sample Are Around the Same Size and Shape, the Granular Soil Is Known as Uniformly Graded Soil. It...

Keeping this in consideration, what is uniformly graded aggregate?
Uniformly Graded - Also known as narrow gradation, a uniform gradation is a sample that has aggregate of approximately the same size. The curve on the gradation graph is very steep, and occupies a small range of the aggregate. It refers to a gradation that contains most of the particles in a very narrow size range.
Similarly, what is the definition of well graded uniformly graded and gap graded of soil? Well Graded soil has particles of wide range of sizes and are distributed in well manner over the soil gradation curve whereas, uniformly graded soil has uniform size of particles throughout. Uniformly graded and gap graded soils are classified as poorly graded soils.
Moreover, what is well graded soil?
A well graded soil is a soil that contains particles of a wide range of sizes and has a good representation of all sizes from the No. 4 to No. 200 sieves. A well graded gravel is classified as GW while a well graded sand is classified as SW.
How do I know if my soil is well graded?
The uniformity coefficient Cu is defined as the ratio of D60 by D10. So when Cu is greater than 4 to 6, it is understood as a well graded soil and when the Cu is less than 4, they are considered to be poorly graded or uniformly graded. Uniformly graded in the sense, the soils have got identical size of the particles.
What are the grades of aggregate?
| IS Sieve Designation | Percentage Passing | |
|---|---|---|
| 10 mm | 100 | 100 |
| 4.75 mm | 90 – 100 | 90 – 100 |
| 2.36 mm | 60 – 95 | 85 – 100 |
| 1.18 mm | 30 – 70 | 75 – 100 |
