Key points
- Increasing asphalt isolating layer thickness increases concrete slab stress and deflection.
- Improved bonding between asphalt and concrete layers reduces stress and deflection.
- Asphalt isolating layer modulus has a minor impact on concrete slab stress and deflection.
- Asphalt isolating layers are suggested for concrete pavement design.

Abstract
A three-dimensional finite element model (3D FEM) is built using ABAQUS to analyze the dynamic response of a concrete pavement structure with an asphalt isolating layer under moving loads. The 3D model is prepared and validated in the state of no asphalt isolating layer. Stress and deflection at the critical load position are calculated by changing thickness, modulus of isolating layer and the combination between the isolating layer and concrete slab. Analysis result shows that the stress and deflection of the concrete slab increase with the increase of thickness. The stress and deflection of the concrete slab decrease with the increase of combination between the isolating layer and concrete slab. The influence of changing the isolating layer modulus to the stress and deflection of the concrete slab is not significant. From the results, asphalt isolating layer design is suggested in concrete pavement.
