Mechanical and Durability Properties of Poorly Graded Sandy Soil Stabilized with Activated Slag
(ASCE, 2020)This study focused on the evaluation of the mechanical and durability aspects of stabilized poorly graded sandy soil by activated blast furnace slag cements (ASCs) with three different activators with combinations of Na2SiO3 ... -
Activation of Blast Furnace Slag with Soda Production Waste
(ASCE, 2020)Although the absence of portland cement (PC) in alkali-activated slag (AAS) lowers its carbon footprint, conventional alkaline activators like sodium silicate are expensive and have large environmental impacts. Soda solid ... -
Fatigue and Rutting Performance of Airfield SBS-Modified Binders Containing High Modulus and Antirutting Additives
(ASCE, 2020)Permanent deformation and fatigue cracking are two main distresses on airfield pavement. To enhance material performances, the researchers introduced three additives in this study: namely, two high modulus agents (HM-1 and ... -
Influence of Surface Morphology of Fibers on the Tensile and Flexural Ductility of Polypropylene-Reinforced Cementitious Composites
(ASCE, 2020)The surface morphology of fibers influence the global performance of fiber-reinforced cementitious composites. Commercially available polypropylene fibers may be coated with polyglycol ester to facilitate the fiber production ... -
Lime- and Cement-Treated Sandy Lean Clay for Highway Subgrade in China
(ASCE, 2020)Sandy lean clay (SLC) has a high content of fine sand and silt with poor compressibility and water stability. It threatens the structural stability of highways in regions where this soil type is common. Improvement of SLC ... -
Nonlinear Modeling of Nanoscaled Properties of Asphalt Binders Recovered from Weathered Asphalt Mixtures
(ASCE, 2020)It is important to investigate the aging mechanism of asphalt binders. To simulate the aging of the binders in asphalt pavements, three mixture gradations of Stone Mastic Asphalt (SMA)-13, Asphalt Concrete (AC)-13, and ... -
Determination of Fracture Parameters of Seawater Sea Sand Concrete Based on Maximum Fracture Load
(ASCE, 2020)Seawater sea sand concrete (SSC) can be applied in islands far away from the mainland. It is essential to clarify the fracture behavior of SSC which is related to the durability under the ocean environment. Thus, the present ... -
Performance Comparison of Laboratory-Produced Short-Term Aged Mixtures with Plant-Produced Mixtures
(ASCE, 2020)Short-term oven aging (STOA) is used in current practice to simulate typical aging of asphalt mixtures during plant production and field construction. This study compares the volumetrics and performance of laboratory-produced ... -
Asphalt Binder Laboratory Short-Term Aging: Effective Parameters and New Protocol for Testing
(ASCE, 2020)This work addresses the effect of time, temperature, airflow rate, and weight of asphalt binder on the laboratory short-term aging of asphalt binders and proposes an alternative protocol that can reduce the aging time and ... -
Aging Evaluation of Amorphous Carbon-Modified Asphalt Binders Using Rheological and Chemical Approach
(ASCE, 2020)Like every other organic compound, asphalt binder experiences aging over time, which significantly affects its chemical and physical properties. This study was the extension of a series of previous research studies in an ... -
Direct Tensile Properties and Stress–Strain Model of UHP-ECC
(ASCE, 2020)This research developed an ultra-high-performance engineered cementitious composite (UHP-ECC), which combines the properties of strain-hardening, multiple cracking, and high mechanical strength. The compressive strength ... -
Extraction of Tricalcium Aluminate for Research Applications by Selective Dissolution of Portland Cement Clinker
(ASCE, 2020)Tricalcium aluminate (C3A) is the most reactive phase in portland cement clinker. In the study of the C3A hydration process, the use of synthetic samples is often preferred over clinker-sourced samples due to the absence ... -
