RISPerformance Evaluation of Asphalt Pavement Resurfacing Treatments Using Structural Equation Modeling
Publisher: ASCE
Abstract: The structural equation modeling (SEM) method was used to evaluate the performance of pavement resurfacing treatments. The pavement performance was regarded as a latent variable that cannot be directly observed, pavement ...
Gradient Boosted Models for Enhancing Fatigue Cracking Prediction in Mechanistic-Empirical Pavement Design Guide
Publisher: American Society of Civil Engineers
Abstract: This study developed a gradient boosted model (GBM) to enhance the fatigue cracking predictive performance of transfer functions in the mechanistic-empirical pavement design guide (MEPDG). Two transfer functions, respectively, ...

Evaluating Recycling Efficiency of Plant-Asphalt Mixtures Containing RAP/RAS
Publisher: ASCE
Abstract: With the continuing increase in the use of recycled asphalt pavement (RAP) and recycled asphalt shingle (RAS) for highway construction, there is a concern over how much of the aged asphalt binder inside RAP/RAS can be ...
Fast 3D Voronoi and Voxel–Based Mesostructure Modeling Method for Asphalt Concrete
Publisher: ASCE
Abstract: A fast three-dimensional (3D) Voronoi and voxel based mesostructure modeling method was proposed for asphalt concrete. This method combine the advantages of the Voronoi diagram, voxel meshing, and take-and-place techniques ...

Investigation into Locking Point of Asphalt Mixtures Utilizing Superpave and Marshall Compactors
Publisher: American Society of Civil Engineers
Abstract: Locking point is an important concept in selecting a proper aggregate gradation in the asphalt mixture design. The locking point can be defined as the moment during asphalt mixture compaction at which an aggregate structure ...
Fracture Performance of Asphalt Concrete under Long-Term Vapor Exposure
Publisher: ASCE
Abstract: Long-term vapor exposure generates persistent moisture gradients across asphalt pavement sections, driving moisture diffusion into asphalt concrete (AC). Moisture in AC weakens the materials and exacerbates the action of ...
3D Mesomechanical Simulation–Based Approach to Determining Representative Volume Element of Asphalt Concrete
Publisher: ASCE
Abstract: This study proposes a three-dimensional (3D) mesomechanical simulation–based approach to determining the representative volume element (RVE) of asphalt concrete. In this approach, 3D mesostructures of asphalt concrete were ...
