This book was released on 1987 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research undertaken consisted of the study of three topics affecting the performance of asphalt concrete mixtures, that is, mixing moisture, oxidative aging and higher tire pressures and axle loads. This thesis presents the findings of the research comprising these three topics. In the first study, the effects of mixing moisture (0,1,3%) and additives (lime, Pavebond Special) on performance of asphalt mixtures were evaluated using repeated load diametral testing of laboratory samples in terms of resilient modulus, fatigue life, and permanent deformation. To evaluate the long-term durability of mixes, the modified Lottman conditioning procedure was used. Test results show that inferior performance occurred for mixes with 3% moisture and the addition of lime resulted in distinct improvement of performance for moist mixtures. In the second study, the effects of oxidative aging on asphalt mixtures used in the construction of three projects in Oregon were evaluated. The repeated load diametral test for mixtures and Fraass test for asphalt cements were used. A modified Pressure Oxidation Bomb (POB) laboratory accelerated aging method with pure oxygen was adopted. As evaluation parameters, the modulus ratio and Fraass breaking temperature are good indicators of the aging rate of mixtures and asphalt cements, respectively. The third study, the effect of increased axle loads and tire pressures of trucks on the performance of asphalt concrete pavements, included a survey of existing truck operating characteristics in Oregon and an investigation of the current mix design criteria. In particular, stability of asphalt mixtures was evaluated. Six different aggregate gradations including the Fuller maximum density gradation using aggregate from four different sources were used. The correlation analyses between creep behavior and mix design criteria of asphalt mixtures were made. The results of the survey showed that 87% of the tires were of radial construction, and the average measured tire pressures of radial and bias are 102 and 82 psi, respectively. Theoretical equivalency factors taking into account the effect of tire pressures were developed. A 25% increase in tire pressure could result in a 40 to 60% increase in equivalency for a dual tired single axle of 18 kips and a tandem axle of 34 kips.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Materials and Pavement Performance Prediction contains the papers presented at the International Conference on Advances in Materials and Pavement Performance Prediction (AM3P, Doha, Qatar, 16- 18 April 2018). There has been an increasing emphasis internationally in the design and construction of sustainable pavement systems. Advances in Materials and Pavement Prediction reflects this development highlighting various approaches to predict pavement performance. The contributions discuss links and interactions between material characterization methods, empirical predictions, mechanistic modeling, and statistically-sound calibration and validation methods. There is also emphasis on comparisons between modeling results and observed performance. The topics of the book include (but are not limited to): • Experimental laboratory material characterization • Field measurements and in situ material characterization • Constitutive modeling and simulation • Innovative pavement materials and interface systems • Non-destructive measurement techniques • Surface characterization, tire-surface interaction, pavement noise • Pavement rehabilitation • Case studies Advances in Materials and Pavement Performance Prediction will be of interest to academics and engineers involved in pavement engineering.

This book was released on 2004-06-02 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book forms the Proceedings of an International RILEM Symposium, the fourth in the series, on Testing of Bituminous Mixes in Budapest, Hungary, October 1990. The aim of the Symposium is to promote tests for the characterization, design and quality control of bituminous mixes which combine the best features of traditional and modern approaches. Among the topics covered are specimen preparation, tests with unique loading (Marshall test, uniaxial tension and creep tests etc), which are used for mix design or control of mechanical properties, and tests with repeated loading, which give information on fatigue, permanent deformation and moduli, especially for mix design.

Available in PDF, EPUB and Kindle. Book excerpt: Structural Behavior of Asphalt Pavements provides engineers and researchers with a detailed guide to the structural behavioral dynamics of asphalt pavement including: pavement temperature distribution, mechanistic response of pavement structure under the application of heavy vehicles, distress mechanism of pavement, and pavement deterioration performance and dynamic equations. An authoritative guide for understanding the key mechanisms for creating longer lasting pavements, Structural Behavior of Asphalt Pavements describes the intrinsic consistency between macroscopic performance and microscopic response, structure and material, as well as global and local performances, and demonstrates the process of pavement analyses and designs, approaching science from empirical analyses. Analyzes the external and internal factors influencing pavement temperature field, and provide a review of existing pavement temperature prediction models Introduces a “Bridge Principle through which pavement performance and fatigue properties are consolidated Defines the intrinsic consistency between macroscopic performance and microscopic response, structure and material, as well as global and local performance Summaries the mechanistic response of pavement structure under the application of heavy vehicle, distress mechanism of pavement, pavement deterioration performance and dynamic equations, and life cycle analysis of pavement

Available in PDF, EPUB and Kindle. Book excerpt: This report contains 27 papers that serve as a testament to the state-of-the-art of civil engineering at the outset of the 21st century, as well as to commemorate the ASCE's Sesquicentennial. Written by the leading practitioners, educators, and researchers of civil engineering, each of these peer-reviewed papers explores a particular aspect of civil engineering knowledge and practice. Each paper explores the development of a particular civil engineering specialty, including milestones and future barriers, constraints, and opportunities. The papers celebrate the history, heritage, and accomplishments of the profession in all facets of practice, including construction facilities, special structures, engineering mechanics, surveying and mapping, irrigation and water quality, forensics, computing, materials, geotechnical engineering, hydraulic engineering, and transportation engineering. While each paper is unique, collectively they provide a snapshot of the profession while offering thoughtful predictions of likely developments in the years to come. Together the papers illuminate the mounting complexity facing civil engineering stemming from rapid growth in scientific knowledge, technological development, and human populations, especially in the last 50 years. An overarching theme is the need for systems-level approaches and consideration from undergraduate education through advanced engineering materials, processes, technologies, and design methods and tools. These papers speak to the need for civil engineers of all specialties to recognize and embrace the growing interconnectedness of the global infrastructure, economy, society, and the need to work for more sustainable, life-cycle-oriented solutions. While embracing the past and the present, the papers collected here clearly have an eye on the future needs of ASCE and the civil engineering profession.
