PaveSpec 3.0 Software....
Paving the Way to Better Roads

Abstract
Through the use of PaveSpec 3.0, State and local highway/ transportation agencies can develop performance-related specifications (PRS) and predict the performance of a constructed pavement. In addition, PaveSpec 3.0 can be used as a technology transfer tool to enable both contractors and highway agencies to get a better understanding of what it takes to construct highway performance pavements. Some of PaveSpec 3.0's specific capabilities include:

• Simulation of pavement in terms of (1) transverse cracking, (2) transverse joint faulting, (3) transverse joint spalling, and (4) pavement smoothness over time.

• Application of a user-defined maintenance and rehabilitation plan to compute life-cycle costs.

• Development of pay factors charts for the following acceptance quality characteristics: (1) strength, (2) thickness, (3) air content, (4) smoothness, and (5) consolidation around dowels. 

• Computation of contractor pay factors from actual construction test results for the above five acceptance quality characteristics.

• Assistance in executing sensitivity analyses on a given developed PRS.
