This book was released on 2015-12-11 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors' database.

Available in PDF, EPUB and Kindle. Book excerpt: An exhaustive review of data on compaction equipment and compaction operations that were available in 1960 are presented. A brief review of the early history of soil compaction and some of the fundamentals of soil mechanics that are applicable to compaction processes are mentioned. Also included are tabulated data on the state highway department specifications for governing compaction requirements and compaction equipment. The most significant aspect is the extensive amount of available data on full- scale field compaction that has been summarized. These data include results from full-scale field tests using 3-wheel power rollers, sheepsfoot-type rollers, pneumatic-tired rollers, vibratory compaction and tamping compactors. For each type of compacting equipment, various factors such as effects on number of passes, effect of weight of roller, depth of compaction, density produced, etc. have been presented. In most cases comparisons between various types of equipment are presented.

Available in PDF, EPUB and Kindle. Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Report 676: Intelligent Soil Compaction Systems explores intelligent compaction, a new method of achieving and documenting compaction requirements. Intelligent compaction uses continuous compaction-roller vibration monitoring to assess mechanistic soil properties, continuous modification/adaptation of roller vibration amplitude and frequency to ensure optimum compaction, and full-time monitoring by an integrated global positioning system to provide a complete GPS-based record of the compacted area--

Book excerpt: This report describes a study of intelligent compaction (IC) technologies, within the context of actual construction projects, for its potential as a component of INDOT's QC/QA for soils. The output from an IC-equipped roller compaction equipment is a real-time area mapping of the compacted lift stiffness as captured by the IC measure. Data was collected to evaluate the correlation between each of two IC measures-compaction meter value (CMV) and machine drive power (MDP)-and in situ embankment quality test measures, the chief in situ test being the dynamic cone penetrometer (DCP) test which INDOT uses for soil embankment acceptance testing. Researchers sought to understand how well the IC measures might assess embankment quality as currently evaluated by the in situ measures. Window-averaged IC measures were compared with the in situ DCP test points. For CMV, a variable correlation was found between the average CMV and DCP values from 74 in situ locations. Also, a limited head-to-head comparison of CMV and MDP with the in situ measures provided some indication that MDP should be studied further. Lessons were learned regarding the elimination of bias in future correlation studies, critical provisions to facilitate best data quality, and important aspects of data management. IC technology holds promise for monitoring the consistency of the soil compaction effort and flagging weak areas in real time during compaction operations. However, further insight is needed regarding the correlation of the DCP measure with both types of IC measures for various soil characterizations and field moisture conditions.

Book excerpt: This paper shows that a semilog plot of optimum dry density versus compaction effort in energy per unit volume gives essentially a straightline relationship. The slope of this line varies with the plasticity and other related properties, the slope becoming steeper as the plasticity increases and the soil becomes more difficult to compact. It is proposed that laboratory compaction tests, conducted at three compaction efforts and plotted as described, be used as a basis for a classification scheme. It is suggested that such data be used for guidance in establishing compaction requirements for different soils and for predetermining the amount of compaction effort necessary to achieve a desired field density.

Available in PDF, EPUB and Kindle. Book excerpt: This book is not, in any case, in total defiance of the Wise Old Man's admonition, for it is not an entirely new book. Rather, it is an outgrowth of a previous treatise, written a decade ago, entitled "Soil and Water: Physical Principles and Processes." Though that book was well enough received at the time, the passage of the years has inevitably made it necessary to either revise and update the same book, or to supplant it with a fresh approach in the form of a new book which might incorporate still-pertient aspects of its predecessor without necessarily being limited to the older book's format or point of view.

Download or read book The Effects of Different Types of Soil on Compaction Curve written by Noor Aishah Jaafar and published by . This book was released on 2007 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils is an important element that must be considered before develop any construction. The good condition of soils is the most important aspect to make sure the structure or building that constructed did not faced any consequences in future. The compaction test must be carried out to increase the strength of the soils. However, there are some factors that might influence the compaction test result. The factors are moisture content, soil type and compaction effort. The objective of this study is to determine the effects of different types of soil on compaction curve. In addition, the range of Optimum moisture content (OMC) and Maximum dry density (MDD) value can also determined. The data collected are from various places and were chosen randomly. The soils are collected from Raub, Bentong, Temerloh, Maran, Universiti Malaysia Pahang and Gambang. From the laboratory test analysis, the value of Liquid limit (LL), Plastic limit (PL) and Plasticity index (PI) were obtained. In addition, the soils were classified by percent of gravel, sand, silt and clay according Unified Soil Classification System (USCS). The study shows that the compaction curves were produced when the value of dry density and moisture content are plotted. The compaction curve can also be divided into four basic types. There are Type A, Type B, Type C and Type D. The different types of compaction curve show the range of OMC and MDD value. The range values of OMC (%) for type A is 9.5% to 16%, type B is 12.5% to 18%, type C is 4% to 21% and type D is 19%. While the value ofMDD (kN/m3) for type A is 16.5 kN/m3 to 18.6 kN/m3, type B 15.8 kN/m3 to 18.3 kN/m3, type C 14.2 kN/m3 to 16.3 kN/m3 and type D 15.6 kN/m3. As a conclusion, the study also proved that, different types of soils produced different type of compaction curve shape where the range of optimum moisture content (OMC) and maximum dry density (MDD) value can also determined. -Author.
