Optimum Rib Design in TMT Rebars to Enhance Fatigue Life While Retaining Bond Strength
(American Society of Civil Engineers, 2018)This paper investigates high-cycle fatigue (HCF) failure in thermomechanically treated (TMT) rebars using fractographic analysis. Most fatigue failures are found to initiate at the root of the transverse ribs, irrespective ... -
Magnetized Water Effect on Compressive Strength and Dosage of Superplasticizers and Water in Self-Compacting Concrete
(American Society of Civil Engineers, 2018)The use of self-compacting concrete (SCC) has been established; however, novel methods for optimizing and providing suitable workability are still developing. The effect of magnetized water on SCC, by keeping the dosage ... -
Evaluating an Eco-Olivine Nanosilica as an Alternative Silica Source in Alkali-Activated Composites
(American Society of Civil Engineers, 2018)In this study, an eco-olivine nanosilica is produced from natural olivine, and then used as an alternative silicate source in synthesizing the silicate-based alkali activator. The effects of silicate origin and dosage on ... -
Failure Behaviors of Oriented Strand Board Material under Quasi-Static and Dynamic Loads
(American Society of Civil Engineers, 2018)Oriented strand board (OSB) is an engineering material used in the building industry. In lieu of its cost-effectiveness and sustainability, OSB has been used widely as the skin layer of structural insulated panel (SIP), ... -
Short- and Longer-Term Effects of Short-Term Aging on Asphalt Mixture Properties
(American Society of Civil Engineers, 2018)This paper uses information collected from a full-scale untrafficked test section originally constructed for an emergency paving demonstration to determine the short- and longer-term effects of short-term aging on mixture ... -
Compaction and Strength Behavior of Tire Crumbles–Fly Ash Mixed with Clay
(American Society of Civil Engineers, 2018)Use of admixtures to improve the engineering behavior of soil is a popular ground improvement technique. Fly ash and tire crumbles are industrial wastes that can be used for the improvement of the engineering behavior of ... -
Durability Performance of Precast Fly Ash–Based Geopolymer Concrete under Atmospheric Exposure Conditions
(American Society of Civil Engineers, 2018)This study investigates the durability of precast fly ash–based geopolymer concrete (GPC) exposed to an outdoor atmospheric environment for 8 years. Core specimens from GPC culverts are tested to determine the effect ... -
Untitled
(American Society of Civil Engineers, 2018)Technologies developed over the last two decades have introduced the use of glass fiber reinforced polymer (GFRP) composite bars as reinforcement in concrete structures when corrosion of the steel reinforcement is likely ... -
Effect of Steam Aging on Performance-Related Properties of Hot Asphalt Mixture
(American Society of Civil Engineers, 2018)This study presents a new laboratory technique for binder aging by using a steam cooker. This new technique is used to study the effect of steam and heat on asphalt during storage and asphalt pavement during its service ... -
Effect of Tension Strain Level on Reinforcement Corrosion
(American Society of Civil Engineers, 2018)Reinforcement corrosion is a general problem about the reliability and durability of concrete structures. A lot of research about the issue of reinforcement corrosion has been done; however, it has focused primarily on ... -
Stress Intensity Factor Based Damage Prediction Model for Plain Concrete under Cyclic Loading
(American Society of Civil Engineers, 2018)Concrete highways and airfield pavements are subjected to a large number of traffic loads, which may cause failure of the pavement due to fatigue. In the present work, an experimental study has been carried out on plain ... -
Modulus Reduction and Damping Increase of Two Sands Reinforced with Polypropylene Fibers
(American Society of Civil Engineers, 2018)Mixing of soils with synthetic fibers has been a well-established approach in geotechnical engineering practice for ground improvement purposes. Of particular interest for most design problems in soil mechanics and earthquake ... -
Time-Temperature-Age Superposition Validation for Linear Viscoelastic Properties of Bituminous Materials
(American Society of Civil Engineers, 2018)Aging, as an integral part of organic materials like asphalt binder, imposes a significant effect on chemical, physical, and performance-related properties of asphalt mixtures. One of the methods that has been proposed for ... -
Time-and-Depth-Dependent Model of Chloride Diffusion Coefficient for Concrete Members Considering the Effect of Coarse Aggregate
(American Society of Civil Engineers, 2018)Chloride-induced reinforcement corrosion is one of the major causes of durability failure of concrete structures in a salty environment. Because concrete is a kind of heterogeneous material, the effect of coarse aggregate ... -
Determination of the Binder Content of Fine Aggregate Matrices Prepared with Modified Binders
(American Society of Civil Engineers, 2018)The first purpose of this paper was to check the applicability of some design methods of fine aggregate matrices (FAM) to modified asphalt binders. Because of shortcomings observed during the replication of those methods, ... -
Improving Freeze-Thaw Resistance and Strength Gain of Roller Compacted Fly Ash Concretes with Modified Absorbent Polymer
(American Society of Civil Engineers, 2018)It is difficult to entrain air into roller compacted concrete (RCC) using conventional air entraining agent (AEA) because of its low cement content. This paper examines whether modified absorbent polymer (MAP) can be used ... -
