Book excerpt: The report contains data on laboratory and field compaction of cohesionless soils obtained from a survey of Corps of Engineers division laboratories, and results of different types of laboratory compaction tests performed in the U.S. Army Engineer Waterways Experiment Station (WES) laboratory on three cohesionless materials. The tests at WES were conducted to study various laboratory compaction test methods used for cohesionless materials. The three materials tested were a poorly graded sand (SP), a well- graded sand (SW), and a sandy gravel (GW). Impact, Providence vibrated density, vibratory table, and gyratory compaction test methods were used. Replicate tests were conducted on each soil to determine the variations in maximum dry density resulting from different test methods. Different technicians conducted the replicate tests in order that the variations in test results due to different techniques could be determined. Selected tests were also conducted on dry and wet specimens to determine the effect of water content on resulting densities. Gyratory tests were conducted using different angles of gyration and different vertical pressures to determine the effects of these variables.

This book was released on 1976 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several physical methods are described for the practical measurement and rating of angularity (shape) of cohesionless soil particles. Angularity is determined by utilizing the fundamental property of a sphere: a sphere has the smallest contact surface area of any shape for a given volume. Therefore, any other shape will exhibit a greater contact surface area and consequently will have a greater frictional resistance which is a function of its degree of angularity. The effects of angularity on the physical behavior (e.g. strength) of cohesionless soils was investigated at various relative compaction densities. For this purpose a combined compaction and direct shear test device constructed from a modified standard Proctor compaction mold was devised. The samples used to determine the effect of particle shape on the physical behavior of cohesionless materials were produced in the lab from pure quartz. This was done in order to avoid the problem of variations due to mineral composition and grain size distributions. It was hoped that this would insure a greater uniformity of test results. In addition, the shear test results derived from lab-produced quartz samples were compared to those of natural field samples in order to determine whether the behavior observed during lab tests was representative of natural field soils. These experiments demonstrated that the strength of a cohesionless material increases with degree of angularity and relative density to an optimum point. Surpassing the optimum value implies substantial particle crushing which reduces the particle interlocking effect and can result in a reduction of soil strength. Crushing is greatest when cohesionless particles are poorly graded, highly angular, and large in size. Generally, the degree of particle crushing influences strength, and particle shape determines the degree of crushing. Shape (angularity), therefore, significantly controls the overall strength of a cohesionless soil.

Available in PDF, EPUB and Kindle. Book excerpt: Control of compaction of cohesionless granular soils is frequently confounded by the lack of adequate test methods. These materials do not compact satisfactorily in the standard moisture-density test, ASTM Method D 698. Thus, methods of soil-compaction control based upon the standard density test, which are appropriate for cohesive-type soils, have been found to be unworkable with many cohesionless soils.

This book was released on 2014-08-29 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by an author with more than 25 years of field and academic experience, Soil Improvement and Ground Modification Methods explains ground improvement technologies for converting marginal soil into soil that will support all types of structures. Soil improvement is the alteration of any property of a soil to improve its engineering performance. Some sort of soil improvement must happen on every construction site. This combined with rapid urbanization and the industrial growth presents a huge dilemma to providing a solid structure at a competitive price. The perfect guide for new or practicing engineers, this reference covers projects involving soil stabilization and soil admixtures, including utilization of industrial waste and by-products, commercially available soil admixtures, conventional soil improvement techniques, and state-of-the-art testing methods. Conventional soil improvement techniques and state-of-the-art testing methods Methods for mitigating or removing the risk of liquefaction in the event of major vibrations Structural elements for stabilization of new or existing construction industrial waste/by-products, commercially available soil Innovative techniques for drainage, filtration, dewatering, stabilization of waste, and contaminant control and removal
