  • What are the advantages and disadvantages of Pavements?

    » High repair costs (ii) Flexible pavements consist of a series of layers, with the highest quality materials at or near the surface The strength of a flexible pavement is a result of building up thick layers and thereby distributing the load over the sub grade; the surface material does not assume the structural strengths as with rigid.

  • Difference Between Flexible And Rigid Pavement

    Flexible pavement has very low modulus of elasticity (less strength) Modulus of elasticity of rigid pavement is very high, because of high strength concrete and more load bearing capacity of the pavement itself Than compared to flexible pavements In flexible pavements, underlying layers play very important role.
