Identification and Characterization of Asphalt Concrete Phases Using Nanoindentation Creep Analysis
(American Society of Civil Engineers, 2019)Asphalt researchers have studied only the bulk state (liquid or semisolid) of asphalt binder using traditional rheometers. In roadway pavements, an asphalt binder never exists in a liquid or semisolid state; rather, it ... -
Determining Number of Specimen Replicates in Support of Pavement Construction Using AASHTO TP 125
(American Society of Civil Engineers, 2019)The bending beam rheometer (BBR) has long been used to test low-temperature properties of asphalt binders in cold regions. More recently, a newly released TP 125 standard by the American Association of State Highway and ... -
Predicting Postconstruction Settlements Generated by Moving Traffic on Highways Built on Soft Soil in China Using Mechanistic-Empirical Design Method
(American Society of Civil Engineers, 2019)Excessive postconstruction settlement of a highway seriously affects its service performance, a problem that deserves attention urgently. This paper describes an exploratory study on predicting postconstruction settlements ... -
Bayesian Analysis of Pavement Maintenance Failure Probability with Markov Chain Monte Carlo Simulation
(American Society of Civil Engineers, 2019)This study presented a Bayesian logistic model to evaluate the failure probability of asphalt pavement preventive treatments. The Markov Chain Monte Carlo (MCMC) simulation using Metropolis-Hasting sampling was adopted for ... -
Reliability Perspective on Optimum Design of Flexible Pavements for Fatigue and Rutting Performance
(American Society of Civil Engineers, 2019)This study presents a reliability-based design optimization (RBDO) framework for evaluating a four-layered flexible pavement system. The major focus of the study is the optimum design of flexible pavements with respect to ... -
Effectiveness and Cost-Effectiveness Evaluation of Pavement Treatments Using Life-Cycle Cost Analysis
(American Society of Civil Engineers, 2019)This paper evaluated the effectiveness and cost-effectiveness of pavement treatments based on the equivalent area method, which uses the area bounded by posttreatment performance curve, threshold, and unified standard ... -
3D Characterization of Aggregates for Pavement Skid Resistance
(American Society of Civil Engineers, 2019)Aggregate morphological characteristics can play an important role in aggregate resistance to polishing and degradation. The Aggregate Imaging System (AIMS) has been one of the most widely used instruments for aggregate-property ... -
Microstructural Evolution of Asphalt Binder under Combined Action of Moisture and Pressure
(American Society of Civil Engineers, 2019)Moisture-induced damage in asphalt mixes can lead to various distresses in the pavement. The primary cause of such distresses is the loss in adhesion and cohesion properties of the asphalt mixes. One of the factors that ... -
Assessment of Mechanical Stability Performance of Asphalt Mixture Using Superpave Gyratory Compactor
(American Society of Civil Engineers, 2019)This study focused on developing a gyratory compactor to be used as a basis for measuring the stability of asphalt mixtures without the need for additional equipment or additional time. This was achieved by modifying the ... -
Deterioration Characteristics of Waterborne Pavement Markings Subjected to Different Operating Conditions
(American Society of Civil Engineers, 2019)Drivers rely on pavement markings to maintain a safe road path, especially during nighttime and challenging weather conditions. The objective of this study was to model the deterioration of waterborne edge-line pavement ... -
Compactability and Mechanical Properties of LNA-Modified Asphalt Concrete
(American Society of Civil Engineers, 2019)Effective compaction is essential for achieving the desired density and better mechanical behavior of asphalt paving mixtures. The higher the mixture compactability, the lesser is the compaction effort required to attain ... -
Impact of Payload Spectra of Heavy Vehicles on Pavement Based on Weigh-in-Motion Data
(American Society of Civil Engineers, 2019)Truck traffic is a crucial factor that results in pavement damage. The increasing demand of freight transport contributes to rising truck volumes. In some countries there is a trend toward using larger vehicles, and road ... -
