... low in field stabilization. This paper presents a study of two different Norwegian molding techniques, including different optimizations to reduce the amount of entrapped air. The specimens are tested for density and strength, and it is shown that the strength increases with increasing density...

... unsaturated soil types, namely Firouzkouh Clay and Sand-Kaolin mixture, each with two different initial densities. During tests, the lateral soil pressure and corresponding lateral strains have been continuously recorded from the at-rest to the active state of the soil. Accordingly, the coefficients...

...Carlos Lam The density of slurries is an important quality-control parameter for many types of geotechnical works, such as slurry trenching, grouting, and bored piling. Although the working range of this parameter has been refined over the years in many standard specifications, surprisingly almost...

...K. Meshram; H. M. Rangwala; P. Sanvaliya; H. S. Goliya One of the key parameters for the performance of a pavement is uniformity of its sub-grade. In situ assessment for the uniformity of the sub-grade is commonly carried out by measuring the density of soil mass. Measurement of the density is done...

... on different densities of EPS geofoam with and without confining pressures. The results showed confining pressures can significantly affect the creep responses of EPS geofoam. Effects of confining pressures on creep deformations were more pronounced at lower densities. 11 01 2014 06 08 2014 19...

Steenhuis The high-energy, highly collimated X-ray beam at the Cornell High Energy Synchrotron Source (CHESS) was used to provide rapid and high-resolution temporal and spatial density distributions in a consolidating saturated clay specimen. Porewater...

...Christopher L. Meehan; Faraz S. Tehrani; Farshid Vahedifard This paper presents and compares the results from a series of in situ density-based and modulus-based compaction control tests that were conducted during construction of a coarse-grained soil embankment. To simulate current construction...

...Jack W. Rolston; Poul V. Lade A compaction control procedure for rockfill is proposed on the basis of a method devised for determination of the maximum density of a mixture of soil, gravel, cobbles, and boulders. The procedure is straightforward and involves compaction of rocks (gravel, cobbles...

...RP Chapuis; M Mbonimpa; M Aubertin; A-M Dagenais The results of compaction tests are usually presented as dry density versus molding water content. In the corresponding graph, the curves of levels of saturation appear as hyperbolas. A new graphical presentation is proposed where the inverse...

... stiffness of sand with different fabrics, densities, and specimen sizes is presented herein. Two types of test containers were utilized and the results indicate that the SSG stiffness obtained from both containers show a similar trend but are offset by a constant value, which might be due to the effect...

...PH Morris; DJ Williams The application of nuclear moisture/density depth gauges to soil deposits has generally relied on calibration by direct correlation with measured values of moisture content and density. In very soft variable deposits such as coal tailings, direct calibration is not possible...
