Key Insights

• 💦 Longitudinal side drains are essential for draining water from embankments and road cuttings.
• 🫥 Catch basins are used in urban areas to collect and redirect water to the sewer line.
• 💦 Shoulder drainage requires proper slope and camber to effectively drain water from the road surface.
• ❓ Median drainage considerations depend on the width and surface materials of the median.

Questions & Answers

Q: What is the purpose of a longitudinal side drain?

A longitudinal side drain is used to drain off excess water from embankments and road cuttings, preventing water from seeping into the embankment and causing damage.

Q: How do catch basins work?

Catch basins collect water from the pavement surface and direct it to the sewer line, helping to prevent water accumulation and potential flooding on the road.

Q: Why is proper slope and camber important for shoulder drainage?

Proper slope and camber ensure that water effectively drains off the shoulder of the road, preventing water accumulation and potential damage to the pavement surface.

Q: What is subsurface drainage?

Subsurface drainage refers to the removal or diversion of excess soil water from the subgrade, which helps maintain a stable moisture level and prevents moisture-related issues in the road.

Summary & Key Takeaways

• Longitudinal side drains are necessary for draining excess water from embankments and road cuttings.

• Catch basins collect water from the pavement surface and direct it to the sewer line.

• Proper slope and camber are important for effective shoulder drainage.
