Explanation:
The group index method of design of flexible pavement is an empirical method based on physical properties of sub-grade soil.
Heading: Empirical method
- The group index method is an empirical method that uses data from physical tests on the sub-grade soil to determine the pavement design.
- Empirical methods are based on observation rather than theory or scientific principles.
Heading: Physical properties of sub-grade soil
- The group index method uses physical properties of the sub-grade soil, such as density, plasticity, and gradation, to determine the design of the pavement.
- These properties are measured using laboratory tests and field observations.
Heading: Group index
- The group index is a numerical value that represents the combined effect of the physical properties of the sub-grade soil on the pavement design.
- The group index is calculated by assigning points to each property based on its significance and summing the points to determine the overall value.
Heading: Flexible pavement design
- The group index method is used to design flexible pavements, which are designed to accommodate a wide range of traffic loads and environmental conditions.
- The design includes the thickness of each layer of the pavement, including the sub-grade, base, and surface layers.
Conclusion:
In conclusion, the group index method of design of flexible pavement is an empirical method that uses physical properties of the sub-grade soil, such as density, plasticity, and gradation, to determine the pavement design. The method is used to design flexible pavements that can accommodate a wide range of traffic loads and environmental conditions.
