Increasing Microwave Heating Efficiency of Asphalt-Coated Aggregates Mixed with Modified Steel Slag Particles
(American Society of Civil Engineers, 2017)Microwave technology has been used in asphalt pavement for years, but microwave heating efficiency of asphalt mixtures needs to be improved. In this paper, steel slag particles were modified by a coprecipitation method for ... -
Using Activated Carbon to Reduce the Volatile Organic Compounds from Bituminous Materials
(American Society of Civil Engineers, 2017)The objective of this research is to characterize the reduction of volatile organic compounds (VOCs) from bituminous materials resulted from activated carbon. A gas chromatography-mass spectrometer (GC-MS) was used to ... -
Stabilization of Highly Expansive Black Cotton Soils by Means of Geopolymerization
(American Society of Civil Engineers, 2017)This article presents a method of geopolymerizing black cotton soil (BCS), a type of highly expansive soil, to ascertain its potential use in subgrades. The BCS is stabilized by alkalis of calcium hydroxide [Ca(OH)2] or ... -
Estimating Mechanistic Parameters for Subgrade Using Gyratory Compaction with Pressure Distribution Analyzer
(American Society of Civil Engineers, 2017)Compaction control for pavement foundations typically consists of determining the optimum water content and maximum dry unit weight from a Proctor test, and then specifies an acceptable water content and dry unit weight ... -
Three-Dimensional Discrete-Element Modeling of Aggregate Homogeneity Influence on Indirect Tensile Strength of Asphalt Mixtures
(American Society of Civil Engineers, 2017)This study aims to investigate the influence of aggregate homogeneity on the indirect tensile (IDT) strength of asphalt mixtures using imaging and discrete-element method. An aggregate homogeneity index, which was used to ... -
Effect of Carbonation Mixing on CO2 Uptake and Strength Gain in Concrete
(American Society of Civil Engineers, 2017)Concrete is well known for its capacity to sequester carbon dioxide (CO2) through carbonation curing. If carbonation mixing can be used to introduce CO2 during concrete mixing, the process is able to enhance the carbon ... -
Extended Digital Image Correlation Method for Mapping Multiscale Damage in Concrete
(American Society of Civil Engineers, 2017)This paper presents a novel extended digital image correlation (EDIC) method for mapping multiscale damage in concrete. The EDIC method is developed based on the distance transformation algorithm, which extends the capability ... -
Preparation Conditions for the Synthesis of Alkali-Activated Binders Using Tungsten Mining Waste
(American Society of Civil Engineers, 2017)This study evaluated the results of preparation conditions for the production of an alkali-activated binder (AAB) based on a binary mixture of tailings from tungsten mine waste (TMW), and waste glass (WG) activated with a ... -
Fatigue-Damage Model of a Pothole-Repairing Composite Structure for Asphalt Pavement
(American Society of Civil Engineers, 2017)Cumulative fatigue damage caused by repeated loads is one of the important factors that leads to formation of asphalt pavement potholes after they have been repaired. Investigations show that a recurring pothole often ... -
Effective Technique to Estimate Cross Model Parameters
(American Society of Civil Engineers, 2017)The Cross model has been successfully used for modeling the shear thinning behavior of asphalt binders. Usually minimization of least squares/absolute error is used for obtaining model parameters. The curve fitted using ... -
Optimized Fresh and Hardened Properties of Strain Hardening Cementitious Composites: Effect of Mineral Admixtures, Cementitious Composition, Size, and Type of Aggregates
(American Society of Civil Engineers, 2017)The present paper thoroughly investigates the effects of mix design with various water-to-binder (W/B) ratios, types of mineral admixture and types and sizes of local sands on the tensile ductility of engineered cementitious ... -

Flexural Fatigue Behavior of a Self-Compacting Ultrahigh Performance Fiber-Reinforced Concrete
(American Society of Civil Engineers, 2017)The flexural fatigue behavior of an ultrahigh performance fiber-reinforced concrete (UHPFRC) is investigated. This UHPFRC is a self-compacting and industrially competitive version of an earlier material developed by the ... -
Mitigation of Calcium Oxychloride Formation in Cement Pastes Using Undensified Silica Fume
(American Society of Civil Engineers, 2017)Certain chloride-based deicing salts can react with calcium hydroxide in cement paste to form calcium oxychloride. Calcium oxychloride formation results in expansive pressures that damage concrete. This study examines the ... -
