Civil Engineering: Thickness of roadbase

Click For Summary
SUMMARY

The discussion focuses on determining the appropriate thickness of a roadbase, specifically using materials such as crushed concrete or crushed sandstone, to support a 7-tonne rig exerting a pressure of 350 kPa. Participants seek guidance on the calculation methods and material properties necessary for this engineering task. The conversation emphasizes the importance of understanding load distribution and material strength in civil engineering applications.

PREREQUISITES
  • Understanding of load-bearing calculations in civil engineering
  • Knowledge of material properties for crushed concrete and crushed sandstone
  • Familiarity with pressure units, specifically kilopascals (kPa)
  • Basic principles of roadbase design and construction
NEXT STEPS
  • Research methods for calculating roadbase thickness for load-bearing applications
  • Study the properties and performance characteristics of crushed concrete and crushed sandstone
  • Explore civil engineering design codes related to road construction
  • Learn about soil mechanics and its impact on roadbase stability
USEFUL FOR

Civil engineers, construction project managers, and students studying road design and materials engineering will benefit from this discussion.

Hi All,

I got this tute question that I need help with.

I need to determine the thickness of a roadbase (can be anything from crushed concrete or crushed sandstone) on top of sand to withhold a 7tonne rig (350kpa).

Any help would be most appreciated.

Thank you!
