 Pavement Design

 Considerations
  • Expansive Soil
  • Flexible Pavement System w/Base Reinf.
Pavement Design
  • HMA Concrete Type B (6’’ Comp. Depth)
  • Flexible Base Course (6’’ Compacted Depth)
  • Subbase Course (10’’ Compc. Depth)
  • Concrete Surface Finish (Striping, Marks, Paving)
AASHTO Design Method
  • Design Reliability = 95%
  • Estimated Number of ESALs over a 25-year maximum performance
