| Description: | Technical Report Abstract: Conventional direct sampling methods of airport pavement evaluation interfere with aircraft operations; therefore, an evaluation procedure based on nondestructive vibratory testing was developed. The procedure considers the parameters of pavement thickness and strength, soil strength, landing gear characteristics, and load repetition through correlation of FAA direct sampling procedures with the nondestructive data form termed the dynamic stiffness modulus, which is calculated from a vibratory load-deflection graph. The results indicated the need for standardized vibratory testing equipment, and specifications for a suggested model were written. Evaluation procedures were developed for rigid and flexible pavements which consider the environmental factors of temperature and frost-thaw action, the importance of test locations and quantities, and stabilized layers. Appendix A presents results of two correlations: (A.) elastic deflection and pavement performance and (B.) dynamic E-modulus and CBR. Appendix B presents the nondestructive testing and performance results on U.S. Army Engineer Waterways Experiment Station test sections and the effects of bound pavement thickness on the nondestructive test results in an attempt to develop overlay design. Appendix C gives procurement specifications for recommended nondestructive test equipment. |
