RISGeneralized Maxwell Viscoelastic Contact Model-Based Discrete Element Method for Characterizing Low-Temperature Properties of Asphalt Concrete
Publisher: American Society of Civil Engineers
Abstract: A universal asphalt concrete discrete element method (DEM) model was established in this paper. Coarse aggregates consisting of balls bonded by elastic contact models were simulated using irregular particles. Asphalt mastic ...

Inorganic Nanoparticle-Modified Asphalt with Enhanced Performance at High Temperature
Publisher: American Society of Civil Engineers
Abstract: Seven types of inorganic nanoparticles were selected to modify the base asphalt used in asphalt concrete pavement. The most suitable one, silicon dioxide (SiO2), was screened out based on its excellence in improving asphalt ...
Effect of Nano-Kaolinite Clay on Rebar Corrosion and Bond Behavior Between Rebar and Concrete
Publisher: ASCE
Abstract: The effect of nano-kaolinite clay (NKC) on the bond behavior between rebar and concrete was studied in a series of experiments. An electrical corrosion method was used to corrode the rebar embedded in concrete specimens. ...
Data-Driven Design for a Modified Asphalt Binder Based on a Reduced Order Model and Simplicial Homology Global Optimization
Publisher: ASCE
Abstract: The orthogonal experimental method is currently the most commonly used tool for determining an appropriate composition of modified asphalt binders. However, it cannot automatically output a reasonable composition when ...
