RISImpact of Rest Period and Stress Paths on Asphalt Concrete Permanent Deformation Behavior
Publisher: ASCE
Abstract: The traditional repeated-load permanent deformation tests for asphalt concrete (AC) considers only the triaxial compression stress state as the critical loading case. These types of experiments may not represent the most ...
System-Level Approach for Identifying Main Uncertainty Sources in Pavement Construction Life-Cycle Assessment for Quantifying Environmental Impacts
Publisher: American Society of Civil Engineers
Abstract: Poor data quality in pavement construction life-cycle inventory (LCI) causes uncertainty in quantifying the associated environmental impact through life-cycle assessment (LCA). To reduce such LCA uncertainty while enhancing ...
Comparative Assessment of Liquid Antistripping Agents and Mineral Admixtures in Asphalt Mix Resistance to Moisture Damage
Publisher: ASCE
Abstract: The main aim of this research was to investigate the effectiveness of liquid antistrips (LASs) as compared with mineral admixtures such as lime and cement in treating moisture sensitivity of asphalt concrete (AC) mixtures ...
Effectiveness of a Pullout Test Method Developed to Characterize Fundamental Fiber-Matrix Interfacial Mechanisms in Viscoelastic Asphalt Concrete
Publisher: American Society of Civil Engineers
Abstract: Current production of fiber-reinforced asphalt concrete (FRAC) is associated with challenges related to performance inconsistencies, workability, and economic feasibility. Understanding fundamentals of fiber-matrix interaction ...
Performance Characterization of Hot In-Place Recycled Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: Despite the widespread use of in-place recycling, limited information is available in the literature on in situ and laboratory properties of materials placed through in-place recycling. The main objectives of present study ...
Statistical Analysis of Hot-Mix Asphalt Pay for Performance versus Quality Control for Performance
Publisher: ASCE
Abstract: Statistical analysis of hot-mix asphalt (HMA) data for quality assurance programs used by the Illinois DOT was conducted. The aim was to quantify the total amount of incentives and disincentives, and distribution of the ...
Verification and Validation of Pavement Models
Publisher: American Society of Civil Engineers
Abstract: Model development activities are increasing in pavement research and engineering applications. At the same time, there is ambiguity and a lack of consistency with regard to checking and quantifying credibility and suitability ...
Chemical Characterization of Biobinder from Swine Manure: Sustainable Modifier for Asphalt Binder
Publisher: American Society of Civil Engineers
Abstract: This paper presents the production, modification, and characterization of biobinder from swine manure. A hydrothermal process was used to convert swine manure to a bio-oil. The bio-oil was fractionated to extract water, ...
New Stochastic Approach of Vehicle Energy Dissipation on Nondeformable Rough Pavements
Publisher: American Society of Civil Engineers
Abstract: The transportation sector is responsible for 27% of greenhouse gas emissions in the United States, implying that it plays an important role in achieving sustainability goals and slowing down the impact of climate change. ...
Stochastic Analysis of Energy Dissipation of a Half-Car Model on Nondeformable Rough Pavement
Publisher:
Abstract: With a large portion of vehicles still relying on the combustion of petroleum, the transportation sector was reported to be responsible for 27% of the greenhouse gas emissions in the United States in 2015. Within a vehicle, ...
