Rigid pavement or Flexible Pavement !! which one is better?
The choice between flexible pavement and rigid pavement depends on the specific project requirements, environmental conditions, cost considerations, and intended use. Each type has its own advantages and disadvantages. Here's a detailed comparison to help determine which is better for different scenarios: Flexible Pavement Definition : Pavement made of bituminous materials (asphalt) that distribute loads over the subgrade through a layered system. Structure : Composed of layers (surface course, base course, sub-base course, and subgrade). Advantages : Cost-Effective (Short-Term) : Lower initial construction cost compared to rigid pavement. Easier Repairs : Damaged sections can be patched or resurfaced quickly and at a lower cost. Flexibility : Adapts to minor subgrade settlement without cracking. Short Construction Time : Faster to construct, which minimizes traffic disruptions. Recyclability : Asphalt can be reused, making it environmentally friendly. Disadvantages : Higher Main
