Summary and recommendations for the implementation of rigid pavement design, construction and rehabilitation techniques

In order to explain observations of significantly different performances for many of the rigid pavements in Texas, a quantitative evaluation was required to relate distress mechanisms to distress manifestation and to develop better predictions of performance. The CTR staff had previously derived underlying principles concerning the mechanistic behavior of composite materials. Maintenance and rehabilitation studies were performed concurrently using information collected from condition survey and surface profile measurements. This information was analyzed in depth in the development of distress prediction models and suitable criteria for use in rehabilitation decision making. The implementation of several innovative rehabilitation techniques is also described.
