Available in PDF, EPUB and Kindle. Book excerpt: The primary response model programmed in the VESY II-M pavement design and analysis structural subsystem provides for the solution of a three-layered viscoelastic pavement system only. This report modifies this primary response model by extending the solution for stresses, strains, and deflections, to an N-Layered viscoelastic system for any value of Poisson's ratio. An approximate probabilistic solution for the N-Layered viscoelastic system is also presented in closed form. A rut-depth prediction model which uses simplified laboratory characterization tests is developed. The resulting pavement design and analysis models are structured into a set of modular subsystems which provide for easy replacement and incorporation of improved components in any one of the subsystems. An initial concept to optimize the procedure for the design of flexible pavement systems is also presented.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is to develop and implement some numerical models to analyze pavement responses under vehicle loading. Firstly, to study the pavement delamination problem, the pavement structure is modeled as an elastic finite layer system subjected to vertical and horizontal loadings over circular areas. By using the finite layer method, the maximum interface shear stress are determined; the maximum interface shear stress can be used to compare with the interface shear strength obtained through simple shear testing to determine reasonable pavement design parameters to prevent delamination failure. Secondly, the responses of a linear viscoelastic pavement system, with asphalt concrete layer of viscoelastic properties, subjected to vertical circular loadings, are analyzed by finite element method using three algorithms: (i) direct time integration; (ii) Fourier transform; (iii) Laplace transform. The inverse Fast Fourier Transform algorithm and the numerical inversion of Laplace transform method of Honig and Hirdes are used. The numerical results of the quasi-static responses by the three algorithms are presented and compared with respect to their accuracy and computational efficiency. To use the viscoelastic model in the pavement analysis, the parameters of the generalized Maxwell model based on the frequency sweep test results are determined by using the software IRIS, which is then assigned as the property of the asphalt concrete layer in a typical pavement structure subjected to a standard dual tire axle loading. Results for the distributions of stress and strain at various times are presented. In the last part of the research, a preliminary study is presented for permanent deformation of asphalt concrete. A simplified one-dimensional elasto-visco-plastic model is implemented and used to analyze the visco-plastic deformation of a cylindrical asphalt concrete sample under one-dimensional loading.

This book was released on 2012-08-30 with total page 1340 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the recent past, new materials, laboratory and in-situ testing methods and construction techniques have been introduced. In addition, modern computational techniques such as the finite element method enable the utilization of sophisticated constitutive models for realistic model-based predictions of the response of pavements. The 7th RILEM International Conference on Cracking of Pavements provided an international forum for the exchange of ideas, information and knowledge amongst experts involved in computational analysis, material production, experimental characterization, design and construction of pavements. All submitted contributions were subjected to an exhaustive refereed peer review procedure by the Scientific Committee, the Editors and a large group of international experts in the topic. On the basis of their recommendations, 129 contributions which best suited the goals and the objectives of the Conference were chosen for presentation and inclusion in the Proceedings. The strong message that emanates from the accepted contributions is that, by accounting for the idiosyncrasies of the response of pavement engineering materials, modern sophisticated constitutive models in combination with new experimental material characterization and construction techniques provide a powerful arsenal for understanding and designing against the mechanisms and the processes causing cracking and pavement response deterioration. As such they enable the adoption of truly "mechanistic" design methodologies. The papers represent the following topics: Laboratory evaluation of asphalt concrete cracking potential; Pavement cracking detection; Field investigation of pavement cracking; Pavement cracking modeling response, crack analysis and damage prediction; Performance of concrete pavements and white toppings; Fatigue cracking and damage characterization of asphalt concrete; Evaluation of the effectiveness of asphalt concrete modification; Crack growth parameters and mechanisms; Evaluation, quantification and modeling of asphalt healing properties; Reinforcement and interlayer systems for crack mitigation; Thermal and low temperature cracking of pavements; and Cracking propensity of WMA and recycled asphalts.

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
