Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research was to develop an overlay design method/procedure that is used for a structural overlay thickness design of flexible pavement in Louisiana based upon (1) in-situ pavement conditions and (2) non destructive test (NDT) methods, specifically the falling weight deflectometer (FWD) and/or Dynaflect. Fifteen overlay rehabilitation projects were selected for this study. These projects were strategically located throughout Louisiana with different traffic levels. At each selected project, NDT deflection tests including the falling weight deflectometer (FWD) and Dynaflect were performed at a 0.1-mile interval. For some of the selected projects, detailed condition survey data including cracking, rut depth, International Roughness Index (IRI), mid-depth temperature, and pavement thickness was also collected. Six NDT-based overlay design methods were selected and used in the overlay thickness design analysis.

This book was released on 1988 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, a rational overlay design method for flexible pavements in Arizona has been developed which includes roughness, fatigue and plastic deformation models. The method is incorporated in a microcomputer program which is also capable of analyzing the economics of other rehabilitation alternatives. During the development of the method, twenty in-service pavement sites were selected from Arizona highways covering various geographical and environmental regions, soil types, pavement conditions and traffic volumes. nondestructive tests (NDT) were performed on these sites using the Falling Weight Deflectometer at three stress levels as well as the Dynaflect. The pavement layers and subgrade moduli were backcalculated from NDT data using both static and dynamic analyses. The moduli of asphaltic layers were further adjusted for temperature. Statistical analysis was performed and the stress sensitivity was found to be small. Cone Penetration tests were further performed to verify the subgrade moduli. Asphalt concrete cores, base and subbase samples and undisturbed subgrade materials. In addition, base and subbase gradation as well as soil classification and Atterberg limits were obtained. The study expanded the data base for material properties in Arizona. This volume is the first in a three volume set. Volume II provides field testing procedure and workstation development and Volume III is a computer user guide.

Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a methodology for testing, evaluation and determination of overlay thickness required for a given pavement section. The overlay design procedure presented makes use of some of the recent developments for analysis and design of asphaltic concrete overlays. The evaluation of in-service pavements includes the use of the deflection parameters developed by testing of the existing pavements with known geometry for determining the moduli of various pavement layers and the required overlay thickness. The method utilizes empirical values and VESYS structural subsystem as an integral approach complementary to each other. Six pavement sections across the State of North Carolina were selected for deflection testing. Deflection parameters were developed to characterize the deflection data from these pavement sections. In addition, VESYS structural system was used to develop nomographs for the interpretation of the measured deflection basin parameters. These nomographs were used to backcalculate the layer moduli form deflection parameters and known layer thicknesses using iterative solutions. The backcalculated layer moduli from these nomographs correspond to the climate conditions that happen to exist during the time of testing and must therefore be adjusted to other climatic conditions. A procedure for such an adjustment is also included in the design procedure. Many different methods have been developed for determining an overlay thickness. These methods can be categorized in three groups : component analysis, deflection based, and analytically based. A mechanistic procedure is described in this paper. This procedure is based on the data and findings of a previous research and has been used to evaluate in-service pavements in North Carolina using Falling Weight Deflectometer (FWD) deflection parameters. The procedure includes four major parts : (a) FWD deflection parameters and data collection, (b) back-calculation of layer moduli, (c) adjustment of layer moduli and (d) prediction of overlay thickness.

Available in PDF, EPUB and Kindle. Book excerpt: This report reviews and evaluates nondestructive testing equipment currently available and used for the dynamic evaluation of pavements and the design of flexible pavement overlays. The equipment described includes Dynaflect and Road Rater steady-state deflection devices and Dynatest and Phoenix falling weight deflectometers. Information presented includes basic equipment descriptions, operational characteristics, and current prices quoted by the manufacturer or distributor. The overall goal of the study described in this report was to provide a rational means by which a specific piece of equipment could be selected for use in the development of an overlay design method in South Carolina.
