This book was released on 2010 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The standard Proctor test has been widely used and accepted for characterizing soil compatibility for field compaction control. This paper presents a time- and cost-effective method to predict standard Proctor compaction characteristics of non-gravel and gravelly soils using a proposed small apparatus. This small apparatus is similar to the standard Proctor apparatus and easily introduced into soil mechanics laboratory. A comparison of the compaction characteristics of non-gravel soils measured from the proposed small apparatus and from the standard Proctor apparatus shows that this small apparatus can be used as an alternative to the standard Proctor apparatus and regarded as a practical tool for non-gravel soils. For gravelly soils, gravel content mainly controls compaction energy transmitted to the fine fraction and hence its compaction characteristics. A relationship between the generalized optimum water content of the fine fraction in the gravelly soil and the gravel content is established. This relationship leads to an effective method of predicting standard Proctor compaction characteristics of gravelly soils compacted in standard molds using compaction results from the proposed small apparatus. Comparisons between the predicted and the measured compaction characteristics are in very good agreement.

Available in PDF, EPUB and Kindle. Book excerpt: Compaction characteristics were made of soils containing gravel in amounts varying from 0 to 50 percent by weight of the total material. The purpose was to obtain data for studying the compaction characteristics of gravelly soils. Three methods are given for calculating the density of the fine fraction in a gravelly soil. A method for controlling the compaction of gravelly soils is suggested. This method involves the use of a correction factor. (Author).
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.

Available in PDF, EPUB and Kindle. Book excerpt: As part of ES 521-A, 'Effect of Maximum Particle Size, Triaxial Compression and Compaction Tests, ' compaction tests were performed on a gravelly material with cohesive binder to determine the effect of large-size particles on maximum dry density and optimum water content and to obtain data for use in preparing the triaxial specimens. The effect of mold diameter and the effect of scalping both with and without replacement for oversize material were also investigated.

Download or read book Effect of Rock Content on Compaction Characteristics of Clayey Gravel written by Bernard B. Gordon and published by . This book was released on 1965 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper contains results of compaction studies which have been conducted by the California Department of Water Resources on the very rocky soil selected for the impervious core of the Oroville Dam in California. The material studied was a clayey sand to clayey gravel containing a percentage of plus No. 4 U. S. Standard sieve size varying up to 65 per cent by dry weight of total sample. Considerable attention was paid to effect on compaction characteristics of varying maximum particle size, mold diameter, and hammer size and weight. Comparisons were made between the moisture-density relationship as determined by test and as computed using a theoretical rock correction factor. Families of curves were developed which showed the influence of moisture content of the minus No. 4 fraction on total sample dry density. The test results support findings by others that total sample maximum densities deviate from theoretically computed values based on the soil fraction at relatively low rock contents. For tests on the minus 1 1⁄2-in. fraction, however, a very small correction factor is needed. The plasticity of the soil fraction is shown to have a noticeable effect on the total sample maximum density.
