Filter by Keyword20 report(s) found with soils in the keywords field In certain regions of the world, designing deep foundations to withstand seismic loading is a reality. Seismic loading of structures and foundations reaches a critical state as a laterally applied force. The response of soils and foundations to repetitive lateral forces is highly complex, relegating... This report is part of an ongoing investigation on the response of individual piles and pile groups to various types of lateral loadings. This research has been undertaken on behalf of the Utah Department of Transportation (UDOT) and the Mountain-Plains Consortium (MPC).
Phase 1 of the study, involved... Soils are an important component of any transportation structure. To improve the engineering properties of these soils, compaction requirements are included in virtually all transportation construction specifications. Field observations indicate however, that soils at near-freezing temperatures may require... This project has investigated the performance of the admixtures during and after leaching has occurred. This report presents information in two main areas of investigation. The first is a soil column study to determine downward, one-dimensional solute transport properties and trends of the admixtures... The results of an erosion control testing study are presented in this report. The purpose of the study was to compare the performance of selected erosion control products under simulated rainfall and sunlight conditions in terms of soil loss reduction and vegetation growth. A total of 19 materials--11... This paper presents results of laboratory tests conducted to determine the effects of additives on the stabilization of unpaved road surfaces. Laboratory tests can be an efficient means of determining which additive will best stabilize a given unpaved road surface, but correlation between laboratory... This report describes a study jointly conducted by the University of Wyoming and the Wyoming Department of Transportation to better understand how selecting an Mr value influences the thickness of an asphalt overlay pavement. The objectives of this study were to: 1) investigate the importance of several... This report describes a study jointly conducted by the University of Wyoming and the Wyoming Department of Transportation to examine the factors influencing the determination of a subgrade resilient modulus value. The objectives of this study were to first, investigate the importance of several fundamental... The primary objective of this study was to investigate the effects of freeze-thaw conditioning and overloading on the resilient modulus (Mr) of subgrade soils susceptible to frost penetration. The Mr values of conditioned samples were compared to unconditioned samples. All Mr values were determined in... This report describes a study to evaluate the use of subgrade resilient modulus for the design of flexible pavements. The objectives of this initial study were to: a) investigate the relationship between resilient modulus and R-value, and b) develop a predictive equation for resilient modulus based on... |
