Drained Shear Strength of Over-Consolidated Compacted Soil-Cement
(American Society of Civil Engineers, 2016)The use of cement as an additive to natural soil has been practiced for a long time in engineering projects. Chemical bonds generated as the result of cement hydration and pozzolanic reactions have been responsible for the ... -
Influence of the Alkali-Silica Reaction on the Mechanical Degradation of Concrete
(American Society of Civil Engineers, 2016)The alkali-silica reaction (ASR) is an important problem that has yet to be completely understood. Owing to the complexity of this phenomenon, a number of studies have been conducted to characterize its kinetics, its impact ... -
Characterization of Segregated Grout Promoting Corrosion of Posttensioning Tendons
(American Society of Civil Engineers, 2016)Segregation of grout applied for the protection of posttensioning steel may cause corrosion of steel wires, leading to serious hazards to the safety of posttensioned structures. Several cases of failure of external tendons ... -
Effects of Microbial Carbonate Precipitation on Transport Properties of Fiber Cement Composites
(American Society of Civil Engineers, 2016)Fibers have been used to improve the mechanical and physical properties of cement-based material since the late 1960s. The inclusion of high-dosage and high-aspect ratio microfibers, however, introduces new interfaces ... -
Experimental Investigation of Rest Time Effect on Permanent Deformation of Asphalt Concrete
(American Society of Civil Engineers, 2016)Asphalt concrete is a complex mixture, the behavior of which is dependent on its components while showing different nonlinear behaviors under various conditions. Application of rest time between compressive loading cycles ... -
Investigation of Aging in Hydrated Lime and Portland Cement Modified Asphalt Concrete at Multiple Length Scales
(American Society of Civil Engineers, 2016)The properties of asphalt concrete are the result of many interdependent physical and chemical mechanisms occurring across multiple length scales. Admixtures such as hydrated lime (HL) and portland cement (PC) are known ... -
Evaluation of Self-Healing Mechanisms in Concrete with Double-Walled Sodium Silicate Microcapsules
(American Society of Civil Engineers, 2015)The objective of this study is to evaluate a new generation of self-healing materials that hold promise for better durability and performance. The in situ polymerization method was used to develop double-walled microcapsules. ... -
Influence of the Freeze-Thaw Cycles on the Physical and Mechanical Properties of Granites
(American Society of Civil Engineers, 2016)Stone masonry buildings provide evidence of the cultural and historical values at the time. Therefore, it is important to preserve the stone of these buildings to harmful environment conditions like freeze-thaw and salt ... -
Influence of Cement on Rheology and Stability of Rosin Emulsified Anionic Bitumen Emulsion
(American Society of Civil Engineers, 2016)Ordinary portland cement (OPC) has been extensively used in cold recycling asphalt and cold-mix asphalt as an additive in order to improve the early age performances of these mixtures. The main purpose of its application ... -
Spent Coffee Grounds–Fly Ash Geopolymer Used as an Embankment Structural Fill Material
(American Society of Civil Engineers, 2016)The drinking of coffee forms a deep-rooted pastime in many communities worldwide. However, the culture of coffee drinking generates vast quantities of organic waste that ends up in landfills. Current research trends are ... -
Performance Evaluation of Hot Mix Asphalt Containing Recycled Asphalt Shingles in Washington State
(American Society of Civil Engineers, 2016)Due to the increasing cost of asphalt binder and also due to environmental considerations, recycled asphalt shingles (RAS) are now allowed to be added into hot mix asphalt (HMA). RAS have been incorporated into HMA with ... -
Influence of Anisotropy on Pavement Responses Using Adaptive Sparse Polynomial Chaos Expansion
(American Society of Civil Engineers, 2016)Modeling the spatial variability that exists in pavement systems can be conveniently represented by means of random fields; in this study, a probabilistic analysis that considers the spatial variability, including the ... -
Extension of Modified Havriliak-Negami Model to Characterize Linear Viscoelastic Properties of Asphalt Binders
(American Society of Civil Engineers, 2016)Accurate characterization of mechanical properties of asphalt binders plays an important role in the evaluation and selection of binders, and in the design and analysis of mixtures. In this study the modified Havriliak-Negami ... -
Evaluation of the Low-Cycle Fatigue Life in Seven Steel Bar Types
