Book excerpt: This report documents the research performed on evaluation of pavement deflection equipment under Contract DTFH61-85-C-00115 for the Federal Highway Administration. The following devices were included in side-by-side field tests conducted in the Austin, Texas area during the week of August 11, 1986: the Benkelman Beam, C.E.B.T.P. Curviameter, Dynaflect, Dynatest Falling Weight Deflectometer (FWD), Kuab FWD, Phonix FWD, and the Road Rater. The report includes descriptions and comparisons of the devices through information obtained from a literature search, field tests and user survey conducted for this study. The side-by-side test program was performed over a broad range of pavement structures, including thick and thin flexible and rigid pavements, and composite pavements. The measured deflections were compared statistically. Mechanistic interpretations of the measured deflection basins were made and compared.

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.

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.
