Ninety per cent of paving failures are base failures. Sub-grade, sub-base material, depth for the loading, compaction in layers, and screeding the bedding layer to a consistent thickness.

The practical task and the checklist below are exactly what this lesson will teach. What is missing is the written explanation and the curated links, each one fetched and verified before it ships.
In the meantime the checklist is genuinely usable on its own. Take it outside.
Checklist
- Sub-grade excavated to design depth and compacted
- Correct sub-base material for the loading, laid in layers
- Each layer compacted with an appropriate compactor
- Bedding layer screeded to a consistent depth, not used to fix level errors
