Abstract

To solve the problems of grid preventing crack, which is used as interlayer between old cement concrete pavement and asphalt overlay, the authors carried through finite element calculations, theoretical analyses, and laboratory tests simulating the field situations. Mechanical analysis proved that grid can obviously reduce the maximum principal stress, equivalent stress, and maximum shear stress at the bottom points of the asphalt overlay. Direct shear layer tests found that the damages occur on the surface of old cement concrete near to grid, the greater the loading rate the easier is it to destroy, and it will obtain best anti-cracking results after roughed treatments. The results showed that glass fiber grid can prevent the reflection cracks from the old cement and asphalt overlay, and can improve the interlayer work, and the roughed treatment on old cement road surface is an important guarantee to achieve this objective.
