Subcommittee D-4 on Road and Paving Materials and published by ASTM International. This book was released on 1994 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: A review of literature concerned with the nondestructive testing of flexible pavements, and two types of testing methods are presented in this report. The first method deals with the measurement of pavement response through the deflection of the pavement surface. Effect of the loading characteristics, pavement structure, and environment on measured deflections are discussed. Experience has shown that deflections of certain magnitudes are associated with failure. Bending strain has also been associated with failure through field measurements of radius of curvature of the deflection basin and through laboratory fatigue studies. The second method involves the application of a vibratory load to the pavement surface and determination of pavement response through deflection of the surface under a low-frequency vibration or by measurement of wave propagation at higher frequencies. The deflection of the pavement under the vibratory loading is used to determine dynamic stiffness, or type of spring constant, for the pavement structure. The wave velocity is used to arrive at a shear modulus and compression modulus of each pavement layer and the subgrade as well as thickness of each layer. Theoretical calculations involved and typical results are presented. Conclusions are made from findings in the literature, and recommendations are given for developing a method of nondestructive evaluation of flexible pavements. (Author).

Book excerpt: Non-destructive testing of pavement structures can be achieved by accurately measuring and interpreting deflection data. this paper describes a computer program designed for simple and fast processing of deflection data collected using a falling weight deflectometer (fwd). a set of diagnostic parameters are calculated: first, maximum horizontal strain in the asphalt concrete (ac) under the test load, directly via the corresponding maximum curvature; next, the elastic stiffness (or young's modulus) of the subgrade; and finally, the vertical stress, strain and deflection on top of the subgrade, by means of an improved method of equivalent layer thickness. the actual stresses, strains, and deflections at test conditions can be normalized for standard ac temperature and standard test load. diagnostic and design applications are discussed. comparisons are made with parallel elastic layer analysis computations. for the covering abstract of the conference see irrd 807201.
