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.

Book excerpt: The Dynaflect and the Falling Weight Deflectometer are commonly used for nondestructive testing of pavements. Although in both cases a dynamic load is imparted, the determination of the mechanical properties of the pavement is normally performed by using static analyses. In this study, the displacements obtained from dynamic analyses are compared to those provided by conventional static programs when the subbase is a homogeneous soil stratum of finite depth, resting on a much stiffer rock-like material and when the soil properties increase smoothly with depth, as is often the case.

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.
