Abstract:

This report is concerned with the design of concrete overlays of old concrete pavements with some remaining fatigue life considering three criteria: (1) wheel load stresses; (2) volume change stresses; (3) interface bond stresses. The finite element method is used for the wheel load stresses and accounts for a more precise modeling of continuously reinforced concrete pavements, jointed reinforced concrete pavements, and jointed concrete pavements with various loading configurations: at edge, at joint, and at cracks. A computer program is presented which performs the required structural analysis using ANSI standard Fortran 77 language and is fully compatible with CDC 170/75 and IBM 3081 hardware's. The structural design has been verified and calibrated using field data from a recently completed thin-bonded concrete overlay (TBCO) experimental project on South IH-610 in Houston. Final design and construction recommendations are made based on this, and previous studies. The design method developed in this study should assist the Texas State Department of Highways and Public Transportation.
