Table 6 Flexural and tensile stiffness and failure load of the composite structure formed by different thicknesses of double-layer pavement under the action of a negative bending moment.
Pavement thickness | 70 mm | 70 mm + 10 mm | 70 mm + 20 mm |
|---|---|---|---|
Flexural and tensile stiffness of the composite structure, in KN/mm) | 18.000 | 20.769 | 24.167 |
Failure load, in KN | 13.5 | 13.5 | 14.5 |
