CBR test is a laboratory test to determine the strength of subgrade soil for highway construction.

• CBR stands for California Bearing Ratio.

• It measures the strength of subgrade soil by comparing the pressure required to penetrate the soil with a standard material.

• CBR values help in designing the thickness of pavement layers for highways.

• Higher CBR values indicate better soil strength and require less pavement thickness.

Embankment is the raised structure built with earth or other materials, while subgrade is the natural ground level beneath the pavement.

• Embankment is man-made, built with materials like soil, rock, or concrete to raise the road level above the surrounding terrain.

• Subgrade is the natural ground level beneath the pavement, prepared to support the road structure.

• Embankment provides stability and support to the road, while...read more

Misdesign of bituminous mix can lead to premature pavement distress and reduced pavement life.

• Improper selection of aggregate gradation

• Incorrect binder content

• Inadequate compaction during construction

• Poor quality control measures

• Lack of proper drainage design

• Failure to consider traffic volume and loadings
