New Asphalt Paving in Orrick
New commercial lots on Orrick's loess-over-clay subgrade require engineered base lifts and moisture management before the first ton of HMA is placed. We build surfaces rated for agricultural staging loads.
- 8–12-inch compacted aggregate base over geotextile fabric on saturated Ray County soils
- 3-inch binder lift using PG 64-22 HMA placed at 290–310°F for heavy-load performance
- 1.5-inch SMA surface course for combine and semi point-load resistance
- Nuclear density testing at 95%+ compaction on every lift before paving proceeds
