This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les chaussées à revêtement souple en béton bitumineux sont largement utilisées dans la construction routière. La conception de ces chaussées doit prendre en compte le comportement des matériaux utilisés, le chargement du trafic et les conditions climatiques.Dans les zones soumises au phénomène de gel, il est primordial de prendre en compte ce phénomène dans la conception des chaussées, leur maintenance et réhabilitation. En effet, ce phénomène peut causer de graves dommages aux chaussées, qui apparaissaient sous forme de fissures ou de déformations excessives. Le présent travail a pour but d'étudier le comportement des chaussées en béton bitumineux sous l'effet couplé du gel et du trafic :Le premier chapitre comporte une synthèse bibliographique des travaux réalisés sur le phénomène du gel-dégel dans les chaussées.Le second chapitre est consacré à la modélisation numérique du phénomène du gel dans les sols traités comme un milieu poreux tri-phasique. Il présente la formulation mathématique de ce problème couplé et sa résolution numérique à l'aide d'une modélisation par différences finies.Le dernier chapitre présente une analyse par éléments finis de la réponse mécanique d'une chaussée au phénomène du gel et du chargement du trafic. L'analyse est menée à l'aide d'une approche simplifiée qui comprend deux étapes: 1) elle consiste à résoudre le problème du gel à l'aide d'une modélisation par différences finies. 2) elle consiste dans la résolution, à l'aide de la méthode des éléments finis, d'un problème mécanique en prenant en compte les chargements d'origine mécanique et le champ de température déterminé d'après l'approche présentée dans le second chapitre.
Book Synopsis Adhesion between polymers and concrete / Adhésion entre polymères et béton by : H. R. Sasse
Download or read book Adhesion between polymers and concrete / Adhésion entre polymères et béton written by H. R. Sasse and published by Springer. This book was released on 2013-11-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Book Synopsis Guidelines for Conducting and Calibrating Road Roughness Measurements by : Michael W. Sayers
Download or read book Guidelines for Conducting and Calibrating Road Roughness Measurements written by Michael W. Sayers and published by . This book was released on 1986 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Road roughness is gaining increasing importance as an indicator of road condition, both in terms of pavement performance, and as a major determinant of road user costs. This paper defines roughness measurement systems hierachically into four groups, ranging from profilometric methods (2 groups), through response type road roughness measuring systems (RTRRMS's), and, subjective evaluation. The International Roughness Index (IRI) is defined, and the programs for it's calculation are provided. The IRI is based on simulation of the roughness response of a car travelling at 80 km/h. The report explains how all roughness measurements can be related to this scale, also when travelling at lower speeds than 80 km/h. The IRI emerges as a scale that can be used both for calibration and for comparative purposes.

Book excerpt: Laboratory and Field Testing is the second volume of the five-volume set Rock Mechanics and Engineering and contains nineteen chapters from key experts in the following fields: - Triaxial or True-triaxial Tests under Condition of Loading and Unloading; - Joint Tests; - Dynamic and Creep Tests; - Physical Modeling Tests; - Field Testing and URLs. The five-volume set “Comprehensive Rock Engineering”, which was published in 1993, has had an important influence on the development of rock mechanics and rock engineering. Significant and extensive advances and achievements in these fields over the last 20 years now justify the publishing of a comparable, new compilation. Rock Mechanics and Engineering represents a highly prestigious, multi-volume work edited by Professor Xia-Ting Feng, with the editorial advice of Professor John A. Hudson. This new compilation offers an extremely wideranging and comprehensive overview of the state-of-the-art in rock mechanics and rock engineering and is composed of peer-reviewed, dedicated contributions by all the key experts worldwide. Key features of this set are that it provides a systematic, global summary of new developments in rock mechanics and rock engineering practices as well as looking ahead to future developments in the fields. Contributors are worldrenowned experts in the fields of rock mechanics and rock engineering, though younger, talented researchers have also been included. The individual volumes cover an extremely wide array of topics grouped under five overarching themes: Principles (Vol. 1), Laboratory and Field Testing (Vol. 2), Analysis, Modelling and Design (Vol. 3), Excavation, Support and Monitoring (Vol. 4) and Surface and Underground Projects (Vol. 5). This multi-volume work sets a new standard for rock mechanics and engineering compendia and will be the go-to resource for all engineering professionals and academics involved in rock mechanics and engineering for years to come.

Book Synopsis Sheep and Goats in Developing Countries by : Winrock International Livestock Research and Training Center
Download or read book Sheep and Goats in Developing Countries written by Winrock International Livestock Research and Training Center and published by . This book was released on 1983 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study are to assess the role of small ruminants (sheep and goats) in the food production systems of developing countries, examine their advantages and disadvantages, analyze the constraints limiting their further contribution to the welfare of small farm/low income rural producers, prescribe measures for overcoming these constraints, and make recommendations related to potential donor involvement in support of the development of sheep and goat production. Small ruminants are viewed as an integral, but not dominant component of complex agricultural systems. Particular emphasis is placed on sheep and goats in mixed herds grazing dry rangelands and in small mixed farm systems in medium to high rainfall areas. An analysis of major constraints -- ecological, biological, policy, and socio-economic -- leads to recommendations on the need for a balanced production system approach for research, training and development programs, and for a combination of support activities such as herd health programs, and formulation of favorable credit, marketing and pricing policies for small ruminants and their products.

Book Synopsis The African Trypanosomiases by : C. W. Lee
Download or read book The African Trypanosomiases written by C. W. Lee and published by World Bank Publications. This book was released on 1983 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tsetse-transmitted trypanosomiases are diseases of man and his domestic livestock that have contributed to the prevalence of poverty, malnutrition, and disease in much of tropical Africa. Although the human disease has caused considerable suffering and death, it is the disease of domestic livestock which has, in economic terms, had the most profound effects as a major factor restricting rural African development, particularly by limiting food supply and land use. After a general discussion of the disease and its effects, this report describes the problems and techniques of controlling tsetse-transmitted trypanosomiases in the context of rural development in Africa. It also attempts to show that techniques to achieve an effective degree of trypanosomaiasis control, at least in some ecological conditions, already exist and that there is now an urgent need to put them into practice in conjunction with practical land use programmes.
