- 1. Permeable Pavement Blocks SustainablePavement System Name of Student: Santosh Yadav M.Tech – 3rd Semester Guide: Mr. Ashis Mehta
- 2. Introduction • Permeable pavementis a sustainable pavement solution. • Allows rainwater to pass through pavement layers. • Reduces surface runoff and water logging. • Improves groundwater recharge.
- 3. Need of PermeablePavement • Urban flooding and water logging issues. • Increased impervious surfaces in cities. • Environmental sustainability requirements. • IRC recommendations for modern pavements.
- 4. IRC Provisions • IRCsupports use of permeable pavements in low-volume roads. • Recommended for parking areas, footpaths and service roads. • Design based on traffic load and drainage capacity.
- 5. Typical Pavement Structure •Permeable concrete or paver blocks on top. • Bedding layer of coarse sand / grit. • Granular base layer for storage. • Filter layer / geotextile. • Prepared subgrade soil.
- 6. Permeable Pavement withKerb • Kerb stones provided for edge confinement. • Improves structural stability. • Suitable for roads and organized parking areas.
- 7. Permeable Pavement withoutKerb • Blocks interlocked without rigid edge. • Used in footpaths and low traffic areas. • Economical and easy to construct.
- 8. Drainage Mechanism • Rainwaterinfiltrates through joints. • Stored temporarily in granular base. • Excess water drained through subgrade or drain pipe. • Reduces load on stormwater drains.
- 9. Applications • Parking areas. •Footpaths and walkways. • Low volume roads. • Residential societies and campuses.
- 10. Advantages • Reduces waterlogging. • Environment friendly. • Improves groundwater recharge. • Easy maintenance and repair.

- 16. Permeable Pavement withSide Drainage Arrangement Permeable Paver Blocks Bedding Layer (Coarse Sand) Open Graded Aggregate Base Asphalt Graded Bed Prepared Subgrade Side Drain (Open Graded Aggregat e) Excess water diverted through side drainage
- 17. Design Considerations (IRCBased) • Traffic category: low to medium volume roads. • Permeability requirement based on rainfall intensity. • Structural capacity of base and subgrade. • Provision of side drainage for excess runoff.
- 18. Construction Methodology • Preparationand compaction of subgrade. • Laying of asphalt graded bed or granular layer. • Placement of open graded aggregate base. • Bedding layer and permeable paver block installation.
- 19. Maintenance Aspects • Regularcleaning of joints to avoid clogging. • Inspection of side drainage system. • Replacement of damaged paver blocks. • Periodic performance evaluation.
- 20. Conclusion • Permeable pavementis an effective sustainable solution. • Reduces water logging and urban flooding. • Improves groundwater recharge. • Highly suitable for Indian urban conditions as per IRC.
