Abstract: Due to the frequent use of the standard penetration test, efforts have been made to standardize the test using energy measurements with electronic calibrators. These calibrators integrate the force-time waveform over the ...

Abstract: Recently soil arching theory has been extended to the study of forces and stresses exerted by a yielding soil mass against discrete piles embedded in a slope and extending into a firm, non‐yielding base. Many uses of ...

Abstract: Jointing can have significant effects on the permeability, shear strength, compressibility, and slope stability of fine‐grained soils. Field measurement of jointing characteristics is an important step in the development ...

Abstract: The purpose of this research was to determine the frictional characteristics of various bedrocks and construction materials against sand under cyclic loading. Laboratory testing was conducted using a direct shear device ...

Abstract: Extensive jointing is a fabric feature that is common to many finegrained soils with high clay content. Both naturally occurring and recompacted soil deposits have been known to exhibit extensively jointed fabrics. Jointing ...

Abstract: This paper describes research undertaken to develop design procedures for using shredded scrap tires as a lightweight fill material in highway construction. The benefits of using scrap tires are particularly enhanced if ...

Abstract: Hydrologic data measured from two earthen final cover test sections constructed on actual landfill final covers are presented with predictions made using two water balance models (HELP and UNSAT-H). Both test sections were ...

Abstract: Water balance data are presented from a capillary barrier test section located on the final cover of a municipal solid waste landfill in a semiarid region (E. Wenatchee, Washington, U.S.). Water balance and meteorological ...

Abstract: Water balance simulations were conducted with the unsaturated flow model UNSAT-H to assess how layer thicknesses, unsaturated hydraulic properties, and climate affect the performance of capillary barriers. Simulations were ...

Abstract: The Federal Highway Administration (FHwA) method and frost-tube measurements are used in Wisconsin to determine the timing and duration of spring load restrictions. In both methods, depth of freeze or thaw is used to ...
