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 predictors of performance. In theory, if all variables influencing the performance of a pavement structure could be correctly evaluated in all possible combinations of their magnitude, duration, and probability of occurrence, it would be possible to predict their effects upon the pavement and thus produce an ideal design. Methods previously used for the design and analysis of rigid pavements originated from concepts which were severely limited by the broad assumptions on which they were based. The CTR staff had previously derived underlying principles concerning the mechanistic behavior of composite materials. This report describes how these principles were used in the development of improved concrete pavement and overlay design procedures. 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. (FHWA)
