Effects of Coarse Aggregate Form, Angularity, and Surface Texture on Concrete Mechanical Performance
(American Society of Civil Engineers, 2019)While aggregates are predominantly responsible for concrete properties, influences of coarse-aggregate shapes (form and angularity) and surface texture on concrete mechanical performance are not well understood. This paper ... -
Assessing Moisture Damage of Asphalt-Aggregate Systems Using Principles of Thermodynamics: Effects of Recycled Materials and Binder Aging
(American Society of Civil Engineers, 2019)This study utilized the concept of surface free energy to assess the effect of binder aging, types of aggregate, and recycled mineral fillers on the moisture susceptibility of asphalt-aggregate systems. A total of 12 ... -
Stress–Strain Relationship Model of Recycled Concrete Based on Strength and Replacement Rate of Recycled Coarse Aggregate
(American Society of Civil Engineers, 2019)The use of recycled coarse aggregate (RCA) can reduce the consumption of natural coarse aggregate (NCA) and preserve the natural environment. The accurate calculation of the compressive stress-strain relationship of recycled ... -
Mechanical Properties of Butt Weldments Made with Q345B Steel and E5015 Electrodes at Different Temperatures
(American Society of Civil Engineers, 2019)The current design standards provide strict recommendations to ensure the quality of welds. This study investigates the mechanical properties of welds subjected to elevated temperatures by performing a steady-state tensile ... -
Tribological Approach to Demonstrate Workability of Foamed Warm-Mix Asphalt
(American Society of Civil Engineers, 2019)Asphalt binder acts as a lubricant film between two aggregates during mixing and compaction. The frictional phenomena in an asphalt–aggregate interaction play an important role in mixing and compaction of warm-mix asphalt ... -
In-Fire and Postfire Mechanical Properties of Duplex Stainless Steel S22053
(American Society of Civil Engineers, 2019)Stainless steel has broad application prospects in building structures because of its favorable corrosion resistance and durability, attractive appearance, and easy conformity with architectural aesthetics. In order to ... -
Tension and Cyclic Behavior of High-Performance Fiber-Reinforced Cementitious Composites
(American Society of Civil Engineers, 2019)In this research the constitutive behavior of high-performance fiber-reinforced cementitious composites (HPFRCCs) was evaluated experimentally under uniaxial monotonic tension and cyclic loading. The experimental program ... -
Investigation into Locking Point of Asphalt Mixtures Utilizing Superpave and Marshall Compactors
(American Society of Civil Engineers, 2019)Locking point is an important concept in selecting a proper aggregate gradation in the asphalt mixture design. The locking point can be defined as the moment during asphalt mixture compaction at which an aggregate structure ... -
Splitting Tensile Strength of Fiber-Reinforced and Biocemented Sand
(American Society of Civil Engineers, 2019)This technical note examines the splitting tensile strength properties of natural sand treated with polyvinyl acetate (PVA) fiber in combination with biocementation using the microbially induced calcite precipitation (MICP) ... -
Chemical and Mechanical Properties of 70-Year-Old Concrete

Early-Age Strength of Alkali-Activated Slag Mortar Based on Burned Oyster Shell and Other Chemical Activators
(American Society of Civil Engineers, 2019)An alkaline-activated, ground-granulated blast furnace slag (BFS) was used as a binder for mortar prepared using river sand. Sixteen mortar mixes with four different BFS:sand ratios (4%, 8%, 12%, and 16% dry weight) were ... -
Measurement of Abrasion on Concrete Surfaces with 3D Scanning Technology
(American Society of Civil Engineers, 2019)Hydraulic structures play an important role in regulation and transport of water in reservoirs and open channels. Examples of such structures include concrete spillways, stilling basins, flumes, weirs, dam, and culverts. ... -
Assessing Binder Blending Level in Asphalt Mixtures Containing Recycled Asphalt Shingles
(American Society of Civil Engineers, 2019)The recycling of asphalt shingles (RAS) in hot mix asphalt (HMA) has been the topic of much research. The asphalt binder of RAS is highly aged, oxidized, and stiffened, and the incorporation of it into HMA may alter the ... -
Surface-Free Energy and Fatigue Performance of Hot-Mix Asphalt Modified with Nano Lime
(American Society of Civil Engineers, 2019)The free energy of asphalt cohesion and of adhesion at the interface of the asphalt binder and aggregate are the main parameters that affect mix asphalt fatigue failure in dry and wet conditions. The free energy of cohesion ... -
