New Asphalt Paving in Smithville
The 169 South Character Area and Employment Overlay District are adding hundreds of thousands of square feet of new commercial asphalt. We build each lot on Clay County-specific base designs that account for extreme shrink-swell subgrade.
- 8–12-inch compacted aggregate base over proof-rolled Clay County plastic clay subgrade
- Two-lift HMA installation — 2.5-inch binder course plus 1.5-inch surface course minimum
- Nuclear density testing to verify 95%+ compaction on every lift before paving
- Mix placement at 290–310°F with rolling completed before mat drops below 185°F
