Available in PDF, EPUB and Kindle. Book excerpt: At present, there is no direct solution that provides the pavement in-situ layer moduli from deflection measurements. Current methods evaluate the pavement layer moduli from deflection measurements using either empirical approaches or layered elastic computer programs with iterative solutions. In this study mechanistically based typical curves are developed to evaluate the moduli of the pavement layers: surface, base, subbase, and subgrade from surface deflection measurements. The curves are developed using the Chevron N-layer computer program with a large number of typical combinations of layer thicknesses and material moduli. The load is assumed to be uniformly applied on a single circular plate with a 304.8-mm (12-in.) diameter, a typical condition of the falling weight deflectometer and the road rater with a single circular plate. Twenty-four sets of curves are developed representing a wide range of layer thicknesses and deflection basin shapes. Therefore, if the layer thicknesses are known and the surface deflection measurements are determined, the four moduli of the pavement layers can be evaluated. The developed curves are simple to use without the need for previous empirical relationships or computer analysis. The curves developed here are based on static analysis.
Book Synopsis Measuring in Situ Mechanical Properties of Pavement Subgrade Soils by : David E. Newcomb
Download or read book Measuring in Situ Mechanical Properties of Pavement Subgrade Soils written by David E. Newcomb and published by Transportation Research Board. This book was released on 1999 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis report will be of interest to pavement and geotechnical design and research engineers, geologists and engineering geologists, and related laboratory personnel. It describes the current practice for measuring in situ mechanical properties of pavement subgrade soils. The tests conducted to measure the mechanical properties of soil strength and stiffness are the primary topics, and these are discussed in the context of design procedures, factors affecting mechanical properties, and the variability of measurements. Information for the synthesis was collected by surveying U.S., Canadian, and selected European transportation agencies and by conducting a literature search. This TRB report provides information on existing and emerging technologies for static and dynamic, and destructive and nondestructive testing for measuring in situ mechanical properties of pavement subgrade soils. Correlations between in situ and laboratory tests are presented. The effects of existing layers on the measurement of subgrade properties, and soil spatial and seasonal variability are discussed. Most importantly, the use of soil properties in pavement design and evaluation are explained. New applications or improvements to existing test methods to support the use of mechanistic/stochastic-based pavement design procedures are also explained.

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.

Download or read book Pavement Deflection Evaluations written by R. Clark Graves and published by . This book was released on 1992 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study a procedure has been developed to evaluate the structural condition of pavements using Road Rater deflection measurements. These procedures compare actual field deflections with deflections calculated by the Chevron N-Layer linear elastic computer program. The results obtained from these procedures are the layer moduli of the pavement materials. Procedures have been developed for asphaltic concrete pavements and composite pavements, including broken and non-broken concrete layers. This report also contains a comparison of structural overlay determined using the results of the new procedure, with overlays calculated using results from the 2-3 Projected procedure currently used by the Pavement Management branch of the Kentucky Transportation Cabinet. A users manual from the computer programs developed during this study is included in the appendix of the report.
