Download or read book A Study of Effective Soil Compaction Control of Granular Soils written by Vincent P. Drnevich and published by Purdue University Press. This book was released on 2007-05-01 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although it is known that impact compaction tests are not appropriate for granular soils, these tests continue to be widely used. Excessive settlements frequently occur in granular soils where specified field compaction is based on Standard Proctor (ASTM D 698; AASHTO T 99) maximum dry unit weights. A laboratory test program evaluated alternative test methods for granular soil compaction control and showed that a Vibrating Hammer method (similar to British Standard BS 1377:1975, Test 14) has great promise for laboratory compaction of these soils.

Book excerpt: Objectives of this field study were to investigate means of compacting soils at near-zero water content. Two 125-ft-long test sections were constructed, each consisting of five test items 25 ft long with a 5-ft-deep test bed. In each test section, the first item consisted of 1.5 ft of crushed limestone (GW) over 3.5 ft of bomb-crater debris. The remaining four items consisted of 5 ft of silty clay (ML0, river sand (CL-ML), gravelly sand (SP), and sand tailings (SP), respectively. One test section was compacted with a single drum self-propelled vibratory roller and the other with a towed four-sided impact single drum sel-propelled vibratory roller and the other with a towed four-sided impact roller. Test results were not fully conclusive because of the difficulty in drying soils with fines, rotational slippage of the impact roller during testing, and precompaction of the soils in the vibratory roller test section during construction. However, it could be concluded that (a) compaction at low water content was feasible primarily with soils with few fines, (b) significant difficulty would be experienced in field-drying soils with high fines content, (c) both compactors generally gave acceptable results, but the rate of compaction of the impact roller was much higher than that of the vibratory roller, and (d) test results warranted further investigation of compaction with the impact roller.

Download or read book Factors that Influence Field Compaction of Soils written by Alfred Walton Johnson and published by . This book was released on 1960 with total page 232 pages. 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.

Download or read book Compaction Comparison Testing Using a Modified Impact Soil Tester and Nuclear Density Gauge written by RA. Erchul and published by . This book was released on 1999 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this paper is to compare test results of a modified Impact Soil Tester (IST) on compacted soil with data obtained from the same soil using a nuclear density gauge at the U.S. Army Corp of Engineer's Buena Vista Flood Wall project in Buena Vista, Virginia. The tests were run during construction of the earth flood wall during the summer of 1996. This comparison testing demonstrated the credibility of the procedure developed for the IST as a compaction testing device. The comparison data was obtained on a variety of soils ranging from silty sands to clays. The Flood Wall comparison compaction data for 90% Standard Proctor shows that the results of the IST as modified are consistent with the nuclear density gauge 89 percent of the time for all types of soil tested. However, if the soils are more cohesive then the results are consistent with the nuclear density gauge 97 percent of the time. In addition these comparison tests are in general agreement with comparison compaction testing using the same testing techniques and methods on compacted backfill in utility trenches conducted earlier for the Public Works Department, Chesterfield County, Virginia.
Download or read book Geotechnics of Roads Fundamentals written by Bernardo Caicedo and published by CRC Press. This book was released on 2018-11-12 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: At first glance, roads seem like the simplest possible geotechnical structures. However, analysis of these structures runs up against complexities related to the intense stresses experienced by road surfaces, their intense interaction with climate, and the complicated behavior of the materials used in road construction. Modern mechanistic approaches to road design provide the tools capable of developing new technical solutions. However, use of these approaches requires deep understanding of the behavior of constituent materials and their interaction with water and heat which has recently been acquired thanks to advances in geotechnical engineering. The author comprehensively describes and explains these advances and their use in road engineering in the two-volume set Geotechnics of Roads, compiling information that had hitherto only been available in numerous research papers. Geotechnics of Roads: Fundamentals presents stresses and strains in road structures, water and heat migration within and between layers of road materials, and the effects of water on the strength and stiffness of those materials. It includes a deep analysis of soil compaction, one of the most important issues in road construction. Compaction accounts for only a small proportion of a construction budget but its effects on the long-term performance of a road are decisive. In addition, the book describes methodologies for nondestructive road evaluation including analysis of continuous compaction control, a powerful technique for real-time quality control of road structures. This unique book will be of value to civil, structural and geotechnical engineers worldwide.
