Analysis of Different Test Methods for Quantifying Rutting Susceptibility of Asphalt Binders
(American Society of Civil Engineers, 2016)Various rutting susceptibility parameters for unmodified and modified bitumen were studied at three different temperatures of 40, 50, and 60°C. Wheel rut testing was also conducted on three different bituminous mixes at ... -
Characterizing Stress–Strain Relationships of Asphalt Treated Base
(American Society of Civil Engineers, 2016)In a flexible pavement, the base course is an essential component in that it supports the surface course and distributes traffic loads to the subbase and subgrade. Asphalt treatment is used on granular base course material ... -
Predictive Models for Storage Modulus and Loss Modulus of Asphalt Mixtures
(American Society of Civil Engineers, 2016)Complex modulus of an asphalt mixture constitutes two components: E′ representing the ability of the mixture to store energy (elastic behavior), and E′′ reflecting the capacity of the material to dissipate energy (viscous ... -
Behavior of Expansive Soil Treated with Steel Slag, Rice Husk Ash, and Lime
(American Society of Civil Engineers, 2016)This paper presents the stabilization of expansive soil (C) with steel slag (SS), rice husk ash (RHA), and quick lime (L). The geotechnical properties, shearing strength characteristics, and dynamic properties of stabilized ... -
Detailed Experimental Review of Flexural Behavior of Cement Stabilized Soil Block Masonry
(American Society of Civil Engineers, 2016)Cement stabilized soil block (CSSB) is a modern earthen building material that is used in the construction of masonry structures. Most studies involving CSSB have focused on how its composition affects strength characteristics ... -
Combined Effect of Water Reducer–Retarder and Variable Chloride-Based Accelerator Dosage on Rapid Repair Concrete Mixtures for Jointed Plain Concrete Pavement
(American Society of Civil Engineers, 2016)On-site addition of accelerator to rapid repair concrete mixtures can result in accidental overdose. Since these mixtures are designed to contain large accelerator dosages, an overdose will produce concrete with extremely ... -
Performance of Multiaxial Paving Interlayer–Reinforced Asphalt Pavement
(American Society of Civil Engineers, 2016)Paving interlayers have been used in asphalt concrete (AC) overlays for a variety of benefits. An earlier study showed that different paving interlayers improved mixture performance, while the multiaxial interlayer provided ... -
Hydric Behavior of Earth Materials and the Effects of Their Stabilization with Cement or Lime: Study on Repair Mortars for Historical Rammed Earth Structures
(American Society of Civil Engineers, 2016)Earthen building materials bear interesting environmental advantages and are the most appropriate to conserve historical earth constructions. To improve mechanical properties, these materials are often stabilized with ... -
Comparison of Laboratory Testing Using SmartRock and Discrete Element Modeling of Ballast Particle Movement
(American Society of Civil Engineers, 2017)Track performance is largely dependent on ballast performance. Unfavorable ballast conditions cause track geometry roughness and can contribute to increased rates of damage and deterioration to the rail, tie, and fastening ... -
Effect of Parallel Plate Gap Height on Repeatability in DSR Measurements of Crumb-Rubber Modified Binders
(American Society of Civil Engineers, 2016)Current Superpave performance grade (PG) grading specification utilizes a dynamic shear rheometer (DSR) at a gap height of 1-mm to determine the high-temperature performance grade of asphalt binders. It has been anticipated ... -
Quantification of Aggregate Morphologic Characteristics as Related to Mechanical Properties of Asphalt Concrete with Improved FTI System
(American Society of Civil Engineers, 2016)This paper introduces the improved Fourier transform interferometry (FTI) system, which captures three-dimensional (3D) high-resolution images of aggregates. The improved FTI system uses the two-dimensional (2D) fast Fourier ... -
Analysis of Crack Microstructure, Self-Healing Products, and Degree of Self-Healing in Engineered Cementitious Composites
(American Society of Civil Engineers, 2016)In this paper, self-healed cracks of engineered cementitious composites (ECC) are observed by optical microscope and scanning electron microscopy, and self-healing products of ECC are analyzed by X-ray diffraction technology. ... -
Nanoindentation and Atomic Force Microscopy Investigations of Asphalt Binder and Mastic
(American Society of Civil Engineers, 2016)Nanoindentation techniques were implemented to calculate and interpret linear viscoelastic properties of asphalt binder and mastic through low-load spheroconical (blunt) nanoindentation. Experiments on three rolling thin-film ... -
Effect of Cyclic Carbonation on Chloride Ingression in GGBS Concrete
