IRC recommends 8-10 passes of vibro roller for full compaction.

• IRC (Indian Road Congress) recommends 8-10 passes of vibro roller for full compaction.

• The number of passes may vary depending on factors such as soil type, moisture content, and thickness of the layer.

• In some cases, additional passes may be required to achieve the desired level of compaction.

• It is important to conduct regular tests to ensure that the desired level of compaction has been achieved.

• Proper compaction ...read more

The quantity of soil in embankment or subgrade can be determined using the method of average end area.

• The method of average end area involves taking cross-sectional measurements at regular intervals along the embankment or subgrade.

• The cross-sectional measurements are used to calculate the area of each section.

• The average area is then multiplied by the length of the embankment or subgrade to determine the volume of soil.

• The formula for calculating the volume is: Volume = Aver...read more

The standard MDD (Maximum Dry Density) of subgrade soil varies depending on the specific project requirements and soil characteristics.

• The standard MDD of subgrade soil is determined through laboratory tests.

• It is influenced by factors such as soil type, compaction method, moisture content, and compaction effort.

• Different soil types have different standard MDD values.

• For example, the standard MDD of a sandy soil may be different from that of a clayey soil.

• The standard MDD is ...read more

The test to determine FDD of soil is called the Falling Head Permeability Test.

• Falling Head Permeability Test is used to determine the coefficient of permeability of soil.

• It involves measuring the time taken for water to flow through a soil sample under a constant head.

• The test is conducted using a permeameter, which consists of a cylindrical tube with a soil sample and a falling head of water.

• The coefficient of permeability is calculated using Darcy's Law.

• The test is useful ...read more
