Book Description
Approximately 10 to 11 million tons of aggregates are utilized in transportation infrastructure projects in Wisconsin annually. The quality of aggregates has a tremendous influence on the performance and durability of roadways and bridges. In this Phase II research study, detailed statistical analyses were performed on over 1,000 sets of historical aggregate test results and the experimental results from the Phase I study. Test results from other states were analyzed as well. Aggregate tests were performed on 12 known marginal or poor Wisconsin aggregates to specifically address test performance of such aggregates. Selected aggregates were scanned using X-ray computed tomography to assess the effects of freeze-thaw and sodium sulfate exposure on the internal void system. The results of multi-parameter logistic regression analyses show that the pass/fail outcomes of the Micro-Deval test can be predicted when LA abrasion, absorption, and sodium sulfate soundness test results are known. The unconfined freeze-thaw test outcomes cannot be predicted from results of other tests (not correlated). Therefore, the unconfined freeze-thaw test should be part of any test protocol as it measures an aggregate characteristic that cannot be obtained from other tests. The percentiles associated with any proposed acceptance threshold limits for various aggregate tests should be determined using the statistical data provided.

Book Description
The maintenance and upgrading of our built environment, including large sections of coastal defences, relies heavily on natural construction materials. The text aims to highlight a range of pressing research issues in natural construction materials of direct relevance to an industry facing growing pressures for environmental sustainability and standardization of product quality within Europe. Tests and specifications given in the forthcoming Eurostandards for aggregates and armourstones are considered and correlated with older more widely used tests, including those which could impact upon current road safety. This text should be useful to: aggregate and amourstone suppliers and users; civil and engineering geologists; quarry companies; and Local and County Authority engineers and coastal engineers.

Book Description
This is the first ever text-cum-reference book in India on “Bituminous Road Construction”. It includes references to the codes and specifications of the Indian Roads Congress and the Bureau of Indian Standards (BIS), besides the international standards such as ASTM and AASHTO. This book provides a thorough knowledge of bituminous road construction such as bitumen; aggregate; mix design; special mixes such as stone matrix asphalt and warm mix asphalt; structural design of flexible pavements; asphalt production and construction; distresses in asphalt pavements; maintenance and rehabilitation of asphalt pavements including recycling; and interesting investigations of premature failure of asphalt pavements across the world. It includes a large number of photographs for easy comprehension of the subject matter. This book has been designed to serve as a text for the undergraduate and postgraduate students of Civil Engineering for the courses on: Highway Materials including Testing Laboratory; Asphalt Mix Design; Highway Construction and Maintenance; Highway Pavement Failures; and Design of Flexible Pavements. Cutting-edge technology on bituminous road constructions, included in the book, helps M.Tech and Ph.D. students in conducting research in this field. Since over 95% of highways have bituminous surface, this book is also an ideal reference for thousands of practicing highway engineers who are engaged in the most ambitious highway construction programme ever in India. Highlights of the Second Edition: • Incorporates cutting-edge technology on the topics covered • Includes new sections on bitumen chemistry; durability of bitumen; Balanced Mix Design (BMD); asphalt mix characterization; perpetual pavements; QC/QA in India; and rehabilitation of distressed concrete pavements with bituminous overlays; and life cycle costs of bituminous versus concrete pavements. TARGET AUDIENCE • B.Tech Civil Engineering • M.Tech Highway Education • Practicing Highway Engineer

Book Description
This book is one out of 8 IAEG XII Congress volumes, and deals with the theme of urban geology. Along with a rapidly growing world population, the wave of urban growth continues, causing cities to swell and new metropolitan centers to emerge. These global trends also open new ventures for underground city development. Engineering geology plays a major role in facing the increasing issues of the urban environment, such as: finding aggregates for construction works; providing adequate water supply and waste management; solving building problems associated to geological and geomorphological conditions; evaluating host rock conditions for underground constructions; preventing or mitigating geological and seismic hazards. Furthermore, this book illustrates recent advancements in sustainable land use planning, which includes conservation, protection, reclamation and landscape impact of open pit mining and alternative power generation. The Engineering Geology for Society and Territory volumes of the IAEG XII Congress held in Torino from September 15-19, 2014, analyze the dynamic role of engineering geology in our changing world and build on the four main themes of the congress: environment, processes, issues and approaches. The congress topics and subject areas of the 8 IAEG XII Congress volumes are: 1. Climate Change and Engineering Geology 2. Landslide Processes River Basins 3. Reservoir Sedimentation and Water Resources 4. Marine and Coastal Processes Urban Geology 5. Sustainable Planning and Landscape Exploitation 6. Applied Geology for Major Engineering Projects 7. Education, Professional Ethics and Public Recognition of Engineering Geology 8. Preservation of Cultural Heritage
