(American Society of Civil Engineers, 2019)This paper presents the effect of ground granulated blast-furnace slag (GGBFS) content on the alkali–silica reaction (ASR) in geopolymer mortar using the accelerated mortar bar test and scanning electron microscope (SEM) ... -
Adhesion of Warm-Mix Recycled Asphalt Aggregate Mixtures Based on Surface Free Energy Theory
(American Society of Civil Engineers, 2019)The present study proposed an adhesion model that incorporates effects of a warming asphalt agent, asphalt, and aggregate in a nonwater or water environment according to the surface free energy theory. The results indicated ... -
Influences of Naphthenic Oil on SBS-Modified Asphalt Binder
(American Society of Civil Engineers, 2019)As an organic solvent, naphthenic oil is used widely in the polymer industry, so it has the potential to be used with polymer to improve the performance of asphalt binder in pavement engineering. The effects of naphthenic ... -
Experimental Investigation of Direct Tension Bond Performance of High-Strength Concrete and Ultrahigh-Performance Concrete Connections
(American Society of Civil Engineers, 2019)The outstanding mechanical and bond strength properties of ultrahigh-performance concrete (UHPC), as well as its long-term durability, make it a suitable material to be used in connections of accelerated bridge construction ... -
Exploratory Study on Bond Behavior of Textured Epoxy-Coated Reinforcing Bars
(American Society of Civil Engineers, 2019)Research and experience have both shown that epoxy-coated reinforcement, the use of which is mandated by most state departments of transportation for bridge decks, increases cracking. Although the epoxy coating protects ... -
Quantifying Effect of Later Curing on Pores of Paste Subject to Early-Age Freeze-Thaw Cycles by Different Techniques
(American Society of Civil Engineers, 2019)Freeze-thaw cycles can damage the microstructure of concrete and reduce the service life of structures, which is particularly detrimental for concrete at very early ages. What size range of pores can be affected by the ... -
Durability and Microstructure Properties of Low-Carbon Concrete Incorporating Ferronickel Slag Sand and Fly Ash
(American Society of Civil Engineers, 2019)Ferronickel slag (FNS) which is also known as electric arc furnace slag is a byproduct of the production of ferronickel alloy. The production of FNS at Société Le Nickel (SLN) in New Caledonia is about 2 Mt per year ... -
Experimental and Modeling Studies of Resilient Modulus and Permanent Strain of Stabilized Fly Ash
(American Society of Civil Engineers, 2019)In the present investigation, geotechnical properties of fly ash lime (FAL) mixes and fly ash cement (FAC) mixes were studied for their use as a subbase material for flexible road pavements. The effects of lime content, ... -
In Situ X-Ray Computed Tomography Experiment on Mesodamage Evolution of Subgrade Bimsoil during Cycle Loading
(American Society of Civil Engineers, 2019)This work revealed the mesodamage evolution in blocks-in-matrix soils (bimsoils) under triaixal cyclic loading. Although the macroscopic cyclic stress-strain responses of bimsoil have been well investigated, the mesoscopic ... -
Preparation and Properties of Bitumen-Modified Polyurethane Solid–Solid Phase Change Materials
