Download or read book Selection of Flexible Pavement Backcalculation Software for the Minnesota Road Research Project written by David A. Van Deusen and published by . This book was released on 1996 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of an evaluation process of several different flexible pavement backcalculation programs. The objective of this study was to compare the performance of the candidate programs in terms of useability and accuracy of backcalculation results. This was accomplished by evaluating the selected programs using both field and simulated data. The results of the analysis were used as the basis for selecting a program for routine analysis of Mn/ROAD pavement deflection data. In situ pavement strains were measured during falling-weight deflectometer tests. The measured strains were then compared to backcalculated strain values from each program. In addition to the field tests, a series of hypothetical pavement structures with a range of prescribed layer thicknesses and moduli were analyzed to obtain surface deflection data. These surface deflections were then used as input for each program involved in the study. The output from each program was compared to the expected values.

Available in PDF, EPUB and Kindle. Book excerpt: The civil engineering sector accounts for a significant percentage of global material and energy consumption and is a major contributor of waste material. The ability to recycle and reuse concrete and demolition waste is critical to reducing environmental impacts in meeting national, regional and global environmental targets. Handbook of recycled concrete and demolition waste summarises key recent research in achieving these goals.Part one considers techniques for managing construction and demolition waste, including waste management plans, ways of estimating levels of waste, the types and optimal location of waste recycling plants and the economics of managing construction and demolition waste. Part two reviews key steps in handling construction and demolition waste. It begins with a comparison between conventional demolition and construction techniques before going on to discuss the preparation, refinement and quality control of concrete aggregates produced from waste. It concludes by assessing the mechanical properties, strength and durability of concrete made using recycled aggregates. Part three includes examples of the use of recycled aggregates in applications such as roads, pavements, high-performance concrete and alkali-activated or geopolymer cements. Finally, the book discusses environmental and safety issues such as the removal of gypsum, asbestos and alkali-silica reaction (ASR) concrete, as well as life-cycle analysis of concrete with recycled aggregates.Handbook of recycled concrete and demolition waste is a standard reference for all those involved in the civil engineering sector, as well as academic researchers in the field. - Summarises key recent research in recycling and reusing concrete and demolition waste to reduce environmental impacts and meet national, regional and global environmental targets - Considers techniques for managing construction and demolition waste, including waste management plans, ways of estimating levels of waste, the types and optimal location of waste recycling plants - Reviews key steps in handling construction and demolition waste
