An overview of existing PM system capabilities showed that there was a need to integrate all of the data collected at CLK and many other airports such that all of the data was used to forecast performance and rehabilitation needs.
Most PM systems rely on single data input and tend to have storage capability for addition data.
If PCI is used, structural modeling is typically not available.

The use of roughness and friction data in the decision process is almost unheard of in most airport PM systems. Dynatest had for some 20 years been modeling road and highway pavement performance using deflection analysis, roughness, friction and distress data.

This high-end PM system is installed in many countries around the world including Denmark, Sweden, England, South Africa, Brazil and the United States.

In 1997 the addition of PERS® (Performance and Economic Rating System) (2) allowed for the affect of historical performance to enhance and refine the pavement modeling process.

Given the huge investment of authorities make in airport pavement, it seemed logical to apply the mechanistic principles used so successfully in the highway and road environment to the airport environment.
