Available in PDF, EPUB and Kindle. Book excerpt: In clod regions, frost action can significantly impact roadway performance due to frost heave and thaw settlement of the subgrade soils. The severity of the damage depends on the soil properties, temperature, freeze-thaw cycles, and water availability. While nominal expansion occurs with the phase change from pore water to ice, heaving is derived primarily from a continuous water flow from the vadose zone to growing ice lenses. The temperature gradient within the soil influences water migration towards the freezing front during winter, where ice nucleates, coalesces into lenses, and grows. When the temperature increases during the spring season, the ice melts, inducing thaw settlement and causing a reduction in soil strength. This study investigated the effect of soil properties, including the gradation and soil thermal properties (thermal conductivity, specific heat, thermal diffusivity), on the frost susceptibility of soils from Iowa and North Carolina through the laboratory frost heave and thaw settlement test. Total heave, heave rate, temperature profile, frost penetration depth, and frost penetration rate were measured as a function of time. The results showed that soils that had higher silt content had higher heaving. Maximum frost penetration rate was observed for soils with higher thermal diffusivity. Moreover, the impact of climatic conditions on frost heave was assessed by conducting tests under varying conditions of water availability (open vs. closed system), multiple freeze-thaw cycles, and temperature gradients. It was observed that the presence of an external water source significantly increased the magnitude of heave, resulting in a seven times higher total heave compared to those soils in a closed system. The soil specimens experienced a continuous increase in heave until the sixth freeze-thaw cycle, after which it stabilized. The freezing process caused the soil specimens to exhibit a high rate of water intake, which decreased during thawing. Under extended freezing periods, both soils showed the maximum total heave when subjected to a lower temperature gradient. The silty sand/silty clay soil experienced more significant frost heave and water intake volume compared to low plasticity clay, owing to its high hydraulic conductivity.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Prepared by the Frozen Ground Committee and the Transportation and Infrastructure Committee of the Cold Regions Engineering Division of ASCEFrost Action in Soils: Fundamentals and Mitigation in a Changing Climate presents the challenges of cold regions engineering in a changing climate, as well as the current practices and state-of-the-art tools for addressing them. Climate change poses questions regarding associated effects on freeze-thaw action and the potential impacts on pavements and other structures in cold regions. In the last 35 years, significant technological advancements addressing frost action in soils have occurred; and tools for instrumentation, measurement, and computer analysis have improved considerably. Thebook explores frost action in soils from different perspectives, as presented in three parts. The first section presents the fundamentals of frost heave and thaw weakening, the impacts on roads and other structures, and the projected effects of climate change on frost action. The second section presents mitigation of frost heave and thaw weakening within pavement structures. The third section highlights three case studies dealing with frost action and mitigation for buildings, roadways, and airfields. This book is a valuable resource for engineers, scientists, and government agencies involved in cold regions engineering and the mitigation of frost action on pavements and other structures

Download or read book Applications of Soil Physics written by Daniel Hillel and published by Elsevier. This book was released on 2012-12-02 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications of Soil Physics deals with the applications of soil physics and covers topics ranging from infiltration and surface runoff to groundwater drainage, evaporation from bare-surface soils, and uptake of soil moisture by plants. Water balance and energy balance in the field are also discussed, along with tillage and soil structure management. The development and extension of Penman's evaporation formula is also described. This book is comprised of 14 chapters and begins with a systematic description of the field-water cycle and its management, with emphasis on infiltration and runoff; redistribution and drainage; evaporation and transpiration; and irrigation and tillage. Subsequent chapters focus on transpiration from plant canopies; freezing phenomena in soils; scaling and similitude of soil-water phenomena; spatial variability of soil physical properties; and movement of solutes during infiltration into homogeneous soil. Concepts of soil-water availability to plants are considered, together with principles of irrigation management and the advantages and limitations of drip irrigation. This monograph is intended for upper-level undergraduate and graduate students of the environmental, engineering, and agronomic sciences.

This book was released on 2012-07-30 with total page 946 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definitive guide to unsaturated soil— from the world's experts on the subject This book builds upon and substantially updates Fredlund and Rahardjo's publication, Soil Mechanics for Unsaturated Soils, the current standard in the field of unsaturated soils. It provides readers with more thorough coverage of the state of the art of unsaturated soil behavior and better reflects the manner in which practical unsaturated soil engineering problems are solved. Retaining the fundamental physics of unsaturated soil behavior presented in the earlier book, this new publication places greater emphasis on the importance of the "soil-water characteristic curve" in solving practical engineering problems, as well as the quantification of thermal and moisture boundary conditions based on the use of weather data. Topics covered include: Theory to Practice of Unsaturated Soil Mechanics Nature and Phase Properties of Unsaturated Soil State Variables for Unsaturated Soils Measurement and Estimation of State Variables Soil-Water Characteristic Curves for Unsaturated Soils Ground Surface Moisture Flux Boundary Conditions Theory of Water Flow through Unsaturated Soils Solving Saturated/Unsaturated Water Flow Problems Air Flow through Unsaturated Soils Heat Flow Analysis for Unsaturated Soils Shear Strength of Unsaturated Soils Shear Strength Applications in Plastic and Limit Equilibrium Stress-Deformation Analysis for Unsaturated Soils Solving Stress-Deformation Problems with Unsaturated Soils Compressibility and Pore Pressure Parameters Consolidation and Swelling Processes in Unsaturated Soils Unsaturated Soil Mechanics in Engineering Practice is essential reading for geotechnical engineers, civil engineers, and undergraduate- and graduate-level civil engineering students with a focus on soil mechanics.

Available in PDF, EPUB and Kindle. Book excerpt: The present paper is one of four prepared for presentation at the January 1959 Annual Meeting of the Highway Research Board and intended to bring out, in the original papers and through prepared discussions, the present and latest basic knowledge concerning frost heave and frost action in soils in relation to pavements. The basic papers cover the factors of (1) water availability, (2) penetration of freezing temperatures, (3) freezing mechanism of soil-water systems, and (4) soil and material types. The present paper covers the last-named of these factors. It reviews the elements which are significant in annual freeze and thaw action in soils and pavement supporting materials. In general, it does not attempt to cover special physical factors encountered only under permafrost conditions. However, the principles brought out herein are, in general, basically applicable not only to frost action which occurs in areas of purely seasonal freezing, but also to that which occurs in the zone of annual freeze and thaw in permafrost regions.
