What is permeability in soil?
Think about how water moves through different soil types.
Why is high permeability desirable for pavement subgrade?
Consider the impact of water on pavement materials.
What is the main consequence of high pore pressure in low permeability soils?
What might happen when water builds up in dense soils?
True or False: High permeability soils are always preferred for pavement design.
Think about connectivity between drainage and pavement performance.
Analyze a scenario in which a highway built on clayey soil experiences severe cracking after repeated rainfalls. What solutions could you propose to alleviate the damage?
Consider the relationship between soil moisture and structural longevity.
Given two pavement designs—one using a high permeability base and the other using a low permeability base—detail the expected performance differences in terms of durability and maintenance.
Think about how water affects soil quality over time.
