Available in PDF, EPUB and Kindle. Book excerpt: "FEDFAA, Finite Element Design-Federal Aviation Administration, is a computer program for both airport rigid and flexible pavement thickness design. NIKE3D (a general-purpose, three-dimensional finite element method (3D-FEM) computer program) is the selected engine for critical stress calculation for airport rigid pavement design. The calculated edge stresses are used in the FEDFAA failure model to determine the slab thickness. Since FEDFAA is a tool for thickness design rather than for analysis, certain program modifications and selection of available elements in NIKE3D have been made during FEDFAA development; it includes (1) selection of the nonconforming eight-node solid element to model all layers of the pavement except the subgrade, (2) introduction of the infinite element to model the infinitely deep subgrade, (3) mesh densities in vertical and horizontal directions, and (4) slab size and width of subbase extension have been determined to fit the needs of the design. A procedure has also been developed to calculate the critical stress of the pavement from the stresses calculated by NIKE3D at the element Gaussian points. Finally, the modified 3D finite element-based program was evaluated by using three criteria: (1) the model must be theoretically correct; (2) the final stress calculation engine with modifications and simplifications provides critical stress close enough to the precise one; and (3) it should be able to complete this computation under aircraft load within a few minutes. This report provides detailed descriptions for model selections, program modifications, and numerical evaluations. The report concludes that the final tool satisfies all three criteria; therefore, it is a reliable and applicable tool for airport rigid pavement design."--P. [ii].

Available in PDF, EPUB and Kindle. Book excerpt: "A comparative analysis of the results of different design methods is a powerful tool for evaluating and developing new pavement design procedures. A sensitivity, or comparative, analysis was employed during the development of Federal Aviation Administration (FAA) Advisory Circular (AC) 150.5320-16 and its computer program LEDFAA. The FAA is currently developing a new Portland cement concrete design procedure based on the three-dimensional finite element method (FEDFAA) and has modified the original subgrade vertical strain-based failure criteria used for flexible pavement design. This report includes a comparison and evaluation of both new construction and overlay designs over a broad range of input conditions."--P. [ii].

Download or read book Concrete Pavement Design Construction and Performance written by Norbert Delatte and published by CRC Press. This book was released on 2018-10-08 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing the interactions between the different design and construction variables and techniques this book illustrates best practices for constructing economical, long life concrete pavements. The book proceeds in much the same way as a pavement construction project. First, different alternatives for concrete pavement solutions are outlined. The desired performance and behaviour parameters are identified. Next, appropriate materials are outlined and the most suitable concrete proportions determined. The design can be completed, and then the necessary construction steps for translating the design into a durable facility are carried out. Although the focus reflects highways as the most common application, special features of airport, industrial, and light duty pavements are also addressed. Use is made of modeling and performance tools such as HIPERPAV and LTPP to illustrate behavior and performance, along with some case studies. As concrete pavements are more complex than they seem, and the costs of mistakes or of over-design can be high, this is a valuable book for engineers in both the public and private sectors.
