CBR test is a laboratory test used to determine the strength of a soil sample.

• CBR stands for California Bearing Ratio.

• It is a penetration test that measures the load-bearing capacity of a soil sample.

• The test involves compacting the soil sample in a mold and subjecting it to a standard load.

• The ratio of the required force to penetrate the soil to the force required for a standard material is calculated.

• CBR values range...read more

GSB layer is a granular sub-base layer used in road construction to provide stability and support.

• GSB layer stands for Granular Sub-Base layer.

• It is typically made up of compacted aggregates like crushed stone or gravel.

• The purpose of the GSB layer is to provide a stable and solid foundation for the road pavement.

• It helps in distributing the load from the pavement to the underlying soil.

• The GSB layer also helps in prev...read more

Chemical test in steel is a process of analyzing the composition of steel to determine its chemical properties.

• Chemical tests are used to determine the amount of carbon, sulfur, phosphorus, and other elements in steel.

• These tests are important for ensuring that the steel meets the required specifications for its intended use.

• One common chemical test is the spectrometric analysis, which uses a spectrometer to measure th...read more

Superelevation is the banking of a road or railway track on a curve to counteract the centrifugal force.

• Superelevation is also known as banking or cant.

• It is used to increase the speed of vehicles on curves without causing discomfort to passengers.

• The amount of superelevation required depends on the design speed and radius of the curve.

• Superelevation is achieved by raising the outer edge of the curve and lowering the i...read more
