Available in PDF, EPUB and Kindle. Book excerpt: The existing FAA overlay design procedures and their history of development are first briefly presented in the report. This is followed by a detailed summary of consultant's reports, which include the identification of deficiencies in the existing procedures with suggested improvements. Immediate improvements to several items in the existing procedures are presented for use as new paragraphs and modification of existing paragraphs in the FAA Advisory Circular. Items to be addressed in a Phase II continuation study are presented. (Author).

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.

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].
