- The pitfalls of cheap paving: thin asphalt overlays on poorly compacted gravel sub-bases crack within two seasons.
- The proper protocol: excavate soft spots, apply dense-graded aggregate base, compact thoroughly, lay a minimum 2-inch asphalt wearing course, then seal-coat biennially.
- Speed control: asphalt speed bumps preserve road longevity by controlling vehicle speeds and reducing braking friction.
Key Takeaway
Proper road sub-base compaction and regular seal-coating protect the community's primary physical asset from premature failure.
