Pavement Evaluation and Overlay Design Using Vibratory Nondestructive Testing and Layered Elastic Theory. Volume II. Validation of Procedure
Author: Richard A. Weiss

Languages : en
Pages : 57
Book Description
A method of pavement evaluation and overlay design based on vibratory nondestructive testing and layered elastic theory was developed in Volume I of this report. Volume II validates this method by comparing it with the conventional methods of evaluation and overlay design for rigid and flexible pavements. Three airport sites were used for the validation. Results of the validation showed good agreement between allowable loads determined from the NDT-elastic theory method and the conventional standard method. However, there was poor agreement between overlay thickness requirements determined from the two methods. (Author).

Pavement Evaluation and Overlay Design Using Vibratory Nondestructive Testing and Layered Elastic Theory. Volume I. Development of Procedure

Pages : 176
Book Description
A procedure is developed for determining the allowable load-carrying capacities and the required overlay thicknesses of airport pavements. A layered elastic theory approach is used with vibratory nondestructive tests supplying the dynamic responses of pavements. For a given pavement, a computer program SUBE is used to determine the value of the subgrade Young's modulus from the measured dynamic responses, and a computer program PAVEVAL, which is based on the layered elastic theory, is used to calculate the allowable load-carrying capacity and the required overlay thickness. Limiting subgrade strains and horizontal stresses in pavement layers are used as criteria for determining load-carrying capacities and overlay thickness requirements. Single- and multiple-wheel loadings are considered. Volume II of this report presents a validation of these procedures for three airport sites. (Author).

Category : Fatigue
Languages : en
Pages : 528
Book Description
The proceedings of June 1993 international symposium held in Atlanta, Georgia, called specifically to develop and standardized evaluation procedures for non-destructive methods of testing pavements. The 29 papers discuss analytical models and techniques, measurement and calculation techniques in the field and laboratory, problems and errors associated with backcalculation methods and design parameters, and testing for other pavement uses. Also includes a history of the quest for a standard and the status of that effort. Reproduced from typescripts. Annotation copyright by Book News, Inc., Portland, OR

A Mechanistic Method for Evaluation of Layer Moduli and Overlay Design

ISBN:
Category : Deflection basin
Languages : en
Pages : 13
Book Description
Nondestructive testing (NDT) has long been used to evaluate flexible pavement structures. The increasing popularity of nondestructive pavement evaluation methods, based on interpretation of surface deflection, has promoted the development of several types of NDT devices. One such device is the falling weight deflectometer (FWD), which is used for the purpose of pavement evaluation in North Carolina. This paper presents a methodology for the testing, evaluation, and determination of overlay thickness required for a given pavement section and subgrade condition. 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 the VESYS structural subsystem as an integral approach complementary to each other.
