Quality Control & Testing
The asphalt batch plant is highly equipped to accurate produce quality asphalt mixes which meet various specifications, outlined by agencies, municipalities and governing bodies. Each mix quality is designed, produced and tested to meet these rigorous standards:
Marshall Stability Test: Measures strength and stability.
Superpave Performance Grading (PG): Evaluates binder performance under different temperatures.
Penetration & Softening Point Test: Determines consistency and temperature susceptibility.
Air Voids & Density Testing: Ensures compaction and longevity.
Moisture Susceptibility Test: Checks for stripping potential.
