This book was released on 1978 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Road test sections of membrane-enveloped silt and clay soils overlain with asphalt cement concrete were subjected to repetitive dynamic plate-bearing loadings to determine their strength variations during freeze-thaw cycles. The recoverable surface deformations in the load deflection bowl were continuously measured during the loading cycles and analyzed using the Chevron layered elastic computer program to obtain the in situ resilient deformation modulus of the various section layers at different stages of the freeze-thaw cycles. The resilient stiffness of the pavement system (the total load per unit of resilient load plate deflection) was also calculated for the various freeze-thaw conditions. The modulus values of the asphalt cement concrete varied inversely with its temperature by an order of magnetide (90,000 psi to 1,300,000 psi). The resilient stiffness of the pavement system varied in the same manner by nearly a factor of eight (228.4 kips/in. to 1740.2 kips/in.). Despite the wide strength variations of the sections during freeze-thaw cycles, membrane-enveloped fine-grained soils can be utilized instead of granular materials as base and subbase layers in flexible pavements in cold regions where moisture migration is a major concern. Moisture migration did not occur at saturation levels up to 75%; thus there was no strength loss during thawing. (Author).

Download or read book Ground Freezing written by Hans L. Jessberger and published by Elsevier. This book was released on 2012-12-02 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developments in Geotechnical Engineering Volume 26: Ground Freezing presents the proceedings of the First International Symposium on Ground Freezing, held in Bochum, Germany on March 8-10, 1978. It summarizes progress in the application of the ground freezing technique in geotechnical engineering, with a focus on engineering with frozen soils and related frost research problems. It includes papers that discuss phase transformation of water, thermodynamics, heat and mass transfer, and mathematical models. The laboratory and theoretical studies of thermophysical and mechanical properties are discussed as well. Organized into 43 chapters, this volume begins with an overview of the freezing and thawing of soils, earth, and rock, and the engineering applications of the favorable properties of frozen ground. It then discusses the mechanical properties of artificially frozen soil for construction purposes, the principles of mechanical and thermal behavior of frozen soil, and the design and calculation of frozen soil-structures. Furthermore, it explains the calculation and dimensioning of refrigeration plants and monitoring of frost penetration. The methods and instrumentation for determining the locations of boundaries of frozen soils and the factors affecting the formation of soil cryogenic textures upon artificial active and passive soil freezing are described. The book also details the influence of salts in the pore water in freezing soils and explains how clay microstructure affects the amount of unfrozen water. In addition, it presents the physicomechanical and thermomechanical properties of frozen coarse-grained soil with sandy clay aggregate. This book will be a valuable source of information for scientists and engineers.
