Available in PDF, EPUB and Kindle. Book excerpt: The Dynamic Cone Penetrometer (DCP) is a device that is used for the estimation of in situ compaction quality of constructed subgrades and embankments. It is a relatively inexpensive, light-weight and easy to use device that measures the dynamic penetration resistance of the compacted soil, from which an estimate of soil strength and stiffness characteristics can be made. Owing to its ease of use, many DOTs in the U.S. have employed the DCP in their compaction quality control procedures, and over the past few decades, extensive research has been carried out on the development of correlations between the results of the DCP test and the results of strength and stiffness tests performed on compacted soils (e.g., California bearing ratio, and resilient modulus)The objectives of this research are to refine DCP-based quality assurance and quality control correlations for compaction quality control developed by previous research studies carried out at Purdue for the Indiana Department of Transportation, especially focusing on (1) grouping of the soils based on their mechanical response to the DCP loading, and (2) limiting the in situ moisture range of the soils used for development of correlations within -2% of the optimum moisture content of the tested soil. The factors outlined above are studied, and in particular, soil grouping is examined critically. The AASHTO ('A-based') classification employed previously for classification of soils is replaced with a new classification criteria specifically developed for the DCP test. Soils are grouped into one of the two categories of coarse-grained or fine-grained soils on the basis of the size of the dominant particle in the soil. The criteria developed for the classification of soil into one of these two categories is based on index properties of the soil, such as the standard Proctor maximum dry density, optimum moisture content, plasticity index (PI) and fines content.
Download or read book Field Book For Quality Control In Earthwork Operations written by Alberto Munguia Mireles and published by iUniverse. This book was released on 2014-08-30 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: The material used for subgrade or embankment construction are variable in color, texture and density-moisture relationship. To adequately control the compaction and field densities of these materials is necessary to know what to expect of the material being use. This field book provides you with some information that will serve this purpose. Soil testing is a quantitative method of quality control for the compacted fill material, and the actual number and types made will depend on the requirements specified by the Designer. The Texas Department of Transportation established those requirements on a document called Schedule for Testing and Sampling. Soil testing should always be specified, conducted and the results closely monitored by the designer, inspector and contractor This field book is used precisely, to collect information on site to fully understand the nature of the material that is being use on the project and to demonstrate that the compacted fill is meeting with soil's properties, densities-moisture relationship and number of testing required. Closely monitoring the information collected on this field book will give the user valuable information that will allow him to properly manipulate the material being processed This field book is a training tool that aggregates civil engineering and construction knowledge that is considered fundamental during the execution of the earthwork

Download or read book Construction Inspection Handbook written by James J. O'Brien and published by Springer. This book was released on 1989 with total page 794 pages. Available in PDF, EPUB and Kindle. Book excerpt: In addition to quality control (QC), this book introduces the concept of quality assurance (QA). Quality assurance has a number of definitions, but in general is the combination of the quality assurance plan with procedures through which the quality control inspector can inspect in the field. The book is arranged in categories so that is can be used in handbook fashion; each section stands independent of the others. The arrangement of the major portion of the book is organized in the same format as we usually find in building construction specification, the Construction Specifications Institute (CSI) format.

Available in PDF, EPUB and Kindle. Book excerpt: Gain a stronger foundation with optimal ground improvement Before you break ground on a new structure, you need to analyze the structure of the ground. Expert analysis and optimization of the geo-materials on your site can mean the difference between a lasting structure and a school in a sinkhole. Sometimes problematic geology is expected because of the location, but other times it's only unearthed once construction has begun. You need to be able to quickly adapt your project plan to include an improvement to unfavorable ground before the project can safely continue. Principles and Practice of Ground Improvement is the only comprehensive, up-to-date compendium of solutions to this critical aspect of civil engineering. Dr. Jie Han, registered Professional Engineer and preeminent voice in geotechnical engineering, is the ultimate guide to the methods and best practices of ground improvement. Han walks you through various ground improvement solutions and provides theoretical and practical advice for determining which technique fits each situation. Follow examples to find solutions to complex problems Complete homework problems to tackle issues that present themselves in the field Study design procedures for each technique to simplify field implementation Brush up on modern ground improvement technologies to keep abreast of all available options Principles and Practice of Ground Improvement can be used as a textbook, and includes Powerpoint slides for instructors. It's also a handy field reference for contractors and installers who actually implement plans. There are many ground improvement solutions out there, but there is no single right answer to every situation. Principles and Practice of Ground Improvement will give you the information you need to analyze the problem, then design and implement the best possible solution.
