QUESTION: 1

### Soil classification based on the particle size distribution is_____________

Solution:

Soil classification of composite soils exclusively based on the particle size distribution is known as textural classification.

QUESTION: 2

### The best known classification system in textural classification is__________

Solution:

Triangular classification of U.S. public road administration is a commonly used system for textural classification.

QUESTION: 3

### Textural classification is most suitable for____________

Solution:

Since the textural classification is based on the percentages of sand, silt, and clay size making up the soil .such a classification is more suitable for describing coarse-grained soil.

QUESTION: 4

To use textural classification chart,___________lines must be drawn.

Solution:

to use the textural classification chart, for a given percentages of three constituents forming a soil, lines are drawn parallel to three sides of the equilateral triangle.

QUESTION: 5

The type of triangle, used in textural classification of soil is_____________

Solution:

A triangle, having equal length of sides (i.e. Equilateral triangle) is used in textural classification chart.

QUESTION: 6

Solution:

HRB classification system, also known as public road administration (PRA) is based on both the particle-size composition and plasticity characteristics.

QUESTION: 7

Solution:

Highway research board classification system is also known as public road administration (PRA) system.

QUESTION: 8

Based on HRB classification system, the soil are divided in to___________

Solution:

Based on HRB system, the soil is divided into 7 primary groups, designated as A-1, A-2…A-7.

QUESTION: 9
