Nondestructive Evaluation of Airport Pavements. Volume I. Program References
The concept of nondestructive evaluation and functional pavement design has been integrated in a computer program which is operational at Transportation Computer center in Washington, D.C. (TCC). The program logic and operational procedures are outlined in this report. The NONDESTRUCTIVE TEST can be used as a substitute for the plate load test without interference to airport operation. All test data are processed and compiled in a NDT inventory file. The strength of existing pavements is evaluated in terms of anticipated functional life as governed by cumulative stress damage and progressive surface deformation. The final program output is the cost information for ten design alternatives of equal functional performance. Correlations have been made between the NDT data and subgrade geology, regional climate, airport operation, existing pavements and response of airport bridges. The current version of FAA standards is open to divergent interpretations and it does not indicate the cost effectiveness of a pavement program. A universal testing procedure has been introduced to evaluate the dynamic response of pavement materials. The program is written in a high level language FORTRAN IV and involves extensive use of data storage and filing techniques.
