RISHistoric Conservation Area Policy and Partial Shrinkage in an Expanding Megacity in China: Microscale Study of 9 <i>Jiedao</i> with 14 Historic Conservation Areas in Old Liwan, Guangzhou, China
Publisher: ASCE
Abstract: Historic conservation is closely connected with the phenomenon of partial shrinkage in the rapidly developing megacity of Guangzhou. Nine jiedao (subdistricts) including 14 historic conservation areas in old Liwan were ...
Optimal Scheduling of Railway Track Possessions in Large-Scale Projects with Multiple Construction Works

Dynamic Viscoelastic Behavior of Multiwalled Carbon Nanotube–Reinforced Magnetorheological (MR) Nanocomposites
Publisher: American Society of Civil Engineers
Abstract: This paper introduces a novel class of three-phase magnetorheological (MR) nanocomposites reinforced with multiwalled carbon nanotubes. Microstructures of the nanocomposites are characterized with the scanning electron ...
Tool Temperature in Titanium Drilling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The spatial and temporal distribution of tool temperature in drilling of commercially pure titanium is studied using the inverse heat transfer method. The chisel and cutting edges of a spiral ...
Microscopic Mechanism of Direct-Input Waste Plastic Modified Asphalt
Publisher: ASCE
Abstract: The continuous pollution of waste plastics to the ecological environment has attracted global attention. Using waste plastics in road construction can save energy, reduce pollution, and improve the high-temperature performance ...
Performance of Dry Mixed Rubber–Plastic Composite Modified Asphalt Mixture
Publisher: ASCE
Abstract: In wet process–modified asphalt, the modifier is easily separated from the asphalt, resulting in poor storage stability. For traditional dry-mixed modified-asphalt mixtures, adding a single modifier to the mixture, it is ...
Decision-Making Model for Evaluating Joint Venture Contractors in Construction of Complex Infrastructure Megaprojects
Publisher: ASCE
Abstract: Due to the complexity of infrastructure megaprojects, using joint venture contractors (JVCs) is an effective method to deliver projects. However, this process is constrained by several factors, including the quality of ...
Evaluation of Rheological and Microscopic Properties of SBS-Modified Asphalt Binder with Multiple Regeneration
Publisher: ASCE
Abstract: Styrene-butadiene-styrene (SBS) modified asphalt binder after aging seriously affects the performance of the road. In this study, waste edible oil, SBS modifier, plasticizer and antiaging agent were used to prepare a new ...
Road Performance of Asphalt Mixture Modified with Liquid Rubber Derived from Crumb Rubber Using Olefin Metathesis
Publisher: American Society of Civil Engineers
Abstract: Liquid rubber (LR) has been proven to be a valuable asphalt modifier capable of addressing the existing deficiencies associated with crumb rubber–modified asphalt (CRMA), including poor workability and storage stability. ...
Experimental and Numerical Analysis of the Friction Drilling Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Friction drilling is a nontraditional hole-making process. A rotating conical tool is applied to penetrate a hole and create a bushing in a single step without generating chips. Friction drilling ...
