advantages and disadvantages of flexible pavement
What are the failures of flexible pavement?
Flexible pavement failure:
Sub-grade failure: Failure of flexible pavement is caused by the localized settlement of any one layer of pavement. Shear failure: Alligator cracking or map cracking: Reflection cracking:What are the advantages of flexible and rigid pavement?
Flexible pavements are easily, quickly constructed and repaired but rigid pavements distresses and may be harder/more expensive to repair.
Generally (but not always) rigid pavements are considered more expensive to construct.Why is flexible pavement important?
Flexible pavement is applied in extremely thick layers, which gives it the ability to withstand heavy and more frequent traffic flows, which makes it the ideal choice for major roadways and highways.
Since regular maintenance is required for this type of pavement, repair work is fairly easy.12 fév. 2019there are three basic problems of flexible pavement design: (1), sufficient thickness of base and surface must be placed over the subgrade to prevent failure within the sub- grade; (2) the shearing strengths of the layers of flexible pavement close to the loaded area, i.e., of the base course and bituminous surface,
