| Abstract | The most common failure modes of concrete pavements are fatigue cracking occurred at concrete slab and/or erosion of materials in sub-layers. Both are related to excessive stresses and deflections on concrete pavement. This study aims to understand the effect of applying several parameters: different axle load configuration; concrete properties; subgrade properties; slab thickness; joint characteristics; shoulder construction; placing bounded HMA overlay on concrete pavement; and adding bounded and unbounded CTB foundation over subgrade, on the fatigue and erosion related distresses in concrete pavements.
The pavement response that may lead to increase both fatigue and erosion failure (the critical stresses and deflections) as the effect of applying each parameter is computed and investigated. KENSLAB, an elaborate finite element program is used to determine the concrete pavement responses: stresses and deflection under the defined parameters. Using this program, concrete pavement is analyzed by the plate theory.
The results obtained using this software is relatively close to known theoretical Westeergaard solutions. Several other findings related to pavement performance and behavior are made through this study. Multiple axles configuration is less damaging than single axle configuration in term of fatigue life. Increasing the thickness is very effective in reducing the edge stress. Using concrete with higher modulus of elasticity brings only small increase to the edge stress. Increasing the slab thickness is the most effective way to increase the fatigue life. Increasing subgrade modulus is more effective in reducing corner deflection than decreases edge stress. The availability of tied shoulder construction gives significant impact in both reducing edge stress and corner deflection. The debonding condition between layers has a significant effect on pavement responses. |
