Initial Assessment of Liquefied Scrap Tire Concrete
(ASCE, 5/1/2021)A new approach to incorporate scrap tire material into concrete was investigated, in which two reclaimed waste tire components, carbon black and fuel oil, were used to replace a portion of water. The effect of liquid tire ... -
Application of Design-Expert Response Surface Methodology for the Optimization of Recycled Asphalt Mixture with Waste Engine Oil
(ASCE, 5/1/2021)In this paper, waste engine oil was used as the base oil to produce a competent rejuvenator for the recycled asphalt mixture based on the Design-Expert surface response method. From the surface response in terms of ... -
Assessing Mechanical Properties of Hard Asphalt Mixtures with Different Design Methods
(ASCE, 6/1/2021)Marginal hard asphalt possesses high stiffness and modulus; however, due to poor ductility at low temperature, it was seldom applied into road structures. Increasing asphalt content seemed to be an effective way to minimize ... -
Experimental Measurements of Interfacial Mechanical Properties between Rehabilitated Bituminous Layers Using Innovative Approaches
(ASCE, 5/1/2021)Bituminous pavements frequently fail at an early age well below the predicted design life, which in turn necessitates taking rehabilitation actions to recover the serviceability to an acceptable level for users. Two ... -
Simulation of the Localized Modulus of Elasticity of Hardwood Boards by Means of an Autoregressive Model
(ASCE, 6/1/2021)An autoregressive (AR) model for the simulation of modulus of elasticity (MOE) fluctuations along hardwood boards without pronounced knot periodicity is presented. The model is calibrated based on contiguous, localized ... -
Nonlinear Time-Dependent Mechanical Behavior of Medium-Density Polyethylene Pipe Material
(ASCE, 5/1/2021)Medium-density polyethylene (MDPE) pipes are extensively used for gas distribution systems in Canada and worldwide. MDPE pipe material possesses time-dependent mechanical properties that govern the performance of the pipes ... -
Material Characterization Approach for Modeling High-Strength Concrete after Cooling from Elevated Temperatures
(ASCE, 5/1/2021)Advanced numerical modeling of high-strength concrete (fc>60 MPa) structures designed to withstand severe thermal conditions requires detailed and reliable information on the mechanical properties of the material exposed ... -
Hydration, Hardening Mechanism, and Performance of Tuff Normal Concrete
(ASCE, 5/1/2021)Using admixtures to replace part of cement can effectively reduce environmental pollution. Many concrete gravity dams have been planned for Tibet, where the resource of fly ash (FA) is scarce but the resource of tuff is ... -
Air-Void System Characterization of Eco-Cellular Concretes
(ASCE, 5/1/2021)Cellular concrete is an alternative to conventional concrete as a low-density and high-insulating building material. The eco-cellular concretes (ECCs) based on geopolymer technology have been recently introduced by the ... -
Effects of an Illite Clay Substitution on Geopolymer Synthesis as an Alternative to Metakaolin
(ASCE, 5/1/2021)In this study, a calcined illite clay from Bailén, Jaén, Spain, was valorized as a substitute of metakaolin in the synthesis of new geopolymeric materials. The raw materials, raw clay and commercial kaolin, were pretreated ... -
Treatment of Bayer-Process Red Mud through Microbially Induced Carbonate Precipitation
(ASCE, 5/1/2021)Microbially induced carbonate precipitation (MICP) was used to treat Bayer-process red mud, a waste product of the aluminum industry. Changes in the unconfined compressive strength (UCS), calcium carbonate content and ... -
Influence of Fiber Content on Acoustic Emission Characteristics Related to Steel Fiber–Reinforced Concrete Subjected to Unconfined Uniaxial Compression
(ASCE, 5/1/2021)This article reports the experimental study of the influence of the fiber volume content in steel fiber–reinforced concrete (SFRC) on the acoustic emission (AE) characteristics. Plain concrete and SFRC specimens with various ... -
Rheological Property Evaluation and Microreaction Mechanism of Rubber Asphalt, Desulfurized Rubber Asphalt, and Their Composites
(ASCE, 6/1/2021)Desulfurized rubber asphalt (DRA) is a good environmentally friendly road construction material, but its high-temperature performance is relatively insufficient compared to ordinary rubber asphalt (RA). Therefore, in order ... -
Influence of Macro- and Microfouling on Corrosion of Steel Bridge Piles Submerged in Natural Waters
(ASCE, 6/1/2021)Anomalous localized corrosion of submerged steel H-piles was detected in a Florida bridge. Microbiological analysis at the site indicated a high population of sulfate-reducing bacteria (SRB). The steel piles coincidently ... -
