This book was released on 1975 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 from 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.

Available in PDF, EPUB and Kindle. Book excerpt: Despite the growing popularity of the crack and seat technique, little guidance is available for use in evaluating and designing overlays for cracked and seated airfield pavements. Towards solving this problem, a case study was undertaken to compare in-situ characteristics and overlay requirements of three different pavement sections at Suffolk Municipal Airport, Virginia. Nondestructive testing was used to determine the in-situ pavement properties and visual surveys were conducted to assess the condition rating of the pavements. The results of the NDT testing program were used to predict and compare the PCC layer moduli and to design AC overlays. The results of the study indicate that: (1) while the use of the crack and seat technique appears to be effective, reflective cracking is not eliminated: (2) the strength of the PCC layer is significantly reduced after cracking and seating and hence, thicker AC overlays are required and (3) a greater degree of cracking before placing the overlay would have been helpful. The uses of a modified FAA flexible pavement procedure for the design of AC overlays is recommended as an interim procedure. NDT testing as a construction quality control device during breaking of the PCC is also recommended.

This book was released on 2017 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of pavement responses is important for better understanding of pavement performance and accurate estimation of pavement service life. This dissertation aims to study flexible pavement responses using forward and inverse analysis. The first objective is development of axisymmetric finite element (FE) models that can simulate FWD loading on the pavement system. After that, the backcalculation of pavement layer moduli from FWD testing was studied by means of soft computing techniques such as Artificial Neural Networks (ANNs) and Genetic Algorithms (GA). The axisymmetric FE models were used to generate a synthetic database. The ANN-GA backcalculating program is developed to assess existing pavement condition after the training and verification using the synthetic database. The second objective of this dissertation is to investigate airfield flexible pavement responses under aircraft loading in consideration of the realistic aircraft tire-pavement interaction. An advanced three-dimensional (3-D) finite element (FE) model was developed to simulate heavy aircraft loading with high tire pressure. The aircraft loading was simulated as moving wheels having non-uniform contact stress distributions. Different tire rolling conditions caused by aircraft ground maneuvering were simulated, including free rolling, full-braking, and turning. The multi-wheel aircraft loading was modeled in two-wheel, four-wheel and six-wheel assembly. The analysis concludes that FWD deflections were affected by dynamic analysis, temperature gradient, bedrock depth, asphalt layer delamination, viscoelasticity, and unbound material nonlinearity. After validated with the field measurements in the long-term pavement performance program (LTPP) database, the developed ANN-GA program can be used to obtain damaged dynamic moduli of asphalt concrete and evaluate in-situ pavement conditions from structural point of view, which facilitates pavement overlay design procedure using Mechanistic-Empirical Pavement Design Guideline (MEPDG). The investigation on airfield flexible pavement emphasized the importance of considering non-uniform tire contact stresses and temperature profiles in airfield pavement analysis. For the aircraft ground maneuvering, aircraft braking or turning significantly increases shear failure potential in asphalt layer. The analysis of stress states would facilitate evaluation of the shear failure potential at airfield asphalt pavements. Finally, the investigation on multi-wheel aircraft loading indicates that the six-wheel gear configuration would cause more fatigue cracking and near-surface cracking potential than dual-wheel and four-wheel gears.
