Download or read book Feasability of Using a Gyratory Compactor to Determine Compaction Characteristics of Soil written by Michael John Browne and published by . This book was released on 2006 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gyratory compaction results, expressed in terms of dry unit weight and optimum moisture content, were compared to traditional laboratory compaction methods (Proctor and relative density tests). These results indicated that each soil type (A-1-a, A- 3, A-4, and A-7-6) was sensitive to one or more of the gyratory compaction variables. When compacted with moisture soil dry unit weights obtained from gyratory compaction surpassed the dry unit weights of traditional compaction methods for the majority of soils tested; therefore, gyratory compaction was considered a feasible and effective method of laboratory soil compaction. A-4 was the only soil whose dry density did not surpass some of traditional compaction tests. Continued research is needed to develop a standardized protocol for gyratory compaction of soils as well as gain a more thorough understanding of free-draining soil. Future studies may also gain a better understanding of gyratory compaction by comparing dry unit weights, pressures, or energies of gyratory compaction to field compaction instead of existing laboratory compaction techniques.

Book excerpt: Tests were performed to determine the effect of three gyratory compactor variables (angle of gyration, vertical pressure, and number of revolutions) on the compaction characteristics of lean clay. The lean clay was also compacted by the impact compaction method for comparison with the gyratory compaction results. These data are to be used for an analysis exploring the use of the gyratory compactor in the design of pavement structures for present and future traffic.

This book was released on 2019-11-26 with total page 3006 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first Pan-American Conference on Soil Mechanics and Geotechnical Engineering (PCSMGE) was held in Mexico in 1959. Every 4 years since then, PCSMGE has brought together the geotechnical engineering community from all over the world to discuss the problems, solutions and future challenges facing this engineering sector. Sixty years after the first conference, the 2019 edition returns to Mexico. This book, Geotechnical Engineering in the XXI Century: Lessons learned and future challenges, presents the proceedings of the XVI Pan-American Conference on Soil Mechanics and Geotechnical Engineering (XVI PCSMGE), held in Cancun, Mexico, from 17 – 20 November 2019. Of the 393 full papers submitted, 335 were accepted for publication after peer review. They are included here organized into 19 technical sessions, and cover a wide range of themes related to geotechnical engineering in the 21st century. Topics covered include: laboratory and in-situ testing; analytical and physical modeling in geotechnics; numerical modeling in geotechnics; unsaturated soils; soft soils; foundations and retaining structures; excavations and tunnels; offshore geotechnics; transportation in geotechnics; natural hazards; embankments and tailings dams; soils dynamics and earthquake engineering; ground improvement; sustainability and geo-environment; preservation of historic sites; forensics engineering; rock mechanics; education; and energy geotechnics. Providing a state-of-the-art overview of research into innovative and challenging applications in the field, the book will be of interest to all those working in soil mechanics and geotechnical engineering. In this proceedings, 58% of the contributions are in English, and 42% of the contributions are in Spanish or Portuguese.

Download or read book Static Method to Determine Compaction Characteristics of Fine Grained Soils written by B. Sharma and published by . This book was released on 2016 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engineering projects such as roads, earthen dams, embankments, and trench backfills require soil compacted at higher dry unit weight. In a majority of geotechnical projects, compaction of soils is involved with increasing strength and decreasing compressibility and permeability. The Proctor compaction test forms one of the most popular and important tests in geotechnical engineering practice. The moisture content-dry unit weight relationship of the soil obtained from the standard Proctor test forms the basis for specification and field compaction control. Standard Proctor test, also known as the dynamic compaction test requires considerable time and effort and has few imperfections. This study examined the possibility of determining the equivalent static pressure to the standard Proctor test to obtain the optimum moisture content, OMC, and maximum dry unit weight, of fine-grained soils. For this, a static compaction pressure test was devised in the Proctor mold itself to statically compact the soil at different water contents. The equivalent static pressure so determined will simplify the compaction procedure and will also result in considerable saving of time, money, and effort, especially so when dealing with highway and earth embankment projects.
