This book was released on 2002 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to develop a mechanistic-empirical method for assessing pavement layer conditions and estimating the remaining life of flexible pavements using multi-load level Falling Weight Deflectometer (FWD) deflections. A dynamic finite element program, incorporating a stress-dependent soil model, was developed to generate the synthetic deflection database. Based on this synthetic database, the relationships between surface deflections and critical pavement responses, such as stresses and strains in each individual layer, have been established. A condition assessment procedure for asphalt pavements that uses multi-load level FWD deflections has been developed using these relationships. The verification study was conducted using field data.

This book was released on 1986 with total page 82 pages. Available in PDF, EPUB and Kindle. 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 1989 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pavement performance studies are being conducted in the states of Nevada and Washington for the purpose of developing mechanistically based pavement design procedures for highways. A critical element of each of these studies is the statewide characterization of the pavement materials. The materials characterization process has included laboratory and field testing for 16 sites in Washington and 27 sites in Nevada.

Download or read book Comparison of the Falling Weight Deflectometer and the Dynaflect for Pavement Evaluation written by Bary Eagleson and published by . This book was released on 1982 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: A literature search was made for the purpose of comparing deflection measuring devices. The Dynaflect, Road Rater, and Falling Weight Deflectometer (FWD) ranked highest when compared, using the criteria of cost, operational characteristics, and suitability. Field testing proved the Dynaflect and FWD were nearly equal in overall ability except in operational speed. Here the Dynaflect was superior primarily due to the automated sensor placement. The correlation coefficients obtained showed good agreement between the deflections measured by the two devices on all pavements tested except overlaid CRCP. This study indicates that there may be pavements and conditions for which the Dynaflect does not provide useful information or where present methods of data interpretation do not appear to be adequate.

Download or read book Use of Falling Weight Deflectometer Data for Assessing Pavement Structural Evaluation Values written by Tanveer Chowdhury and published by . This book was released on 1999 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structural evaluation can be very useful at the network level for project prioritization purposes. In the project priority ranking procedure of the Kansas Department of Transportation (KDOT), a pavement rating attribute, Pavement Structural Evaluation (PSE), is used. These ratings are subjective. his study outlines an approach based on the classical multiple regression analysis resulting in a better estimation of the PSE values using the results from the Falling Weight Deflectometer (FWD) tests and network-level distress survey. The regression models proposed in this study predict the decrease in PSE values by taking into account the FWD data, age, thickness, and distress levels of pavements, and very closely approximate the current PSE ratings obtained at the district level.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The need to accurately characterize the structural condition of existing pavements has increased with the recent development, release, and ongoing implementation of the Mechanistic-Empirical Pavement Design Guide (MEPDG). A number of different material inputs are required in the procedure, and it is important to adequately characterize and define them. The analysis of deflection data collected by the falling weight deflectometer (FWD) provides a quick and reliable way to characterize the properties of the paving layers, as well as to assess the load-carrying capacity of existing pavement structures. With the release of the new MEPDG, there is a pressing need to identify and evaluate the way that FWD testing is integrated into the new design procedure. Moreover, as highway agencies continue to implement the MEPDG, they need best practices guidance on how to effectively test existing pavement structures and interpret the results as part of a mechanistic-empirical pavement evaluation and rehabilitation process.
