Low-Temperature Performance of Toner-Modified Asphalt Binder
(American Society of Civil Engineers, 2019)Waste nanotoner is a semiheavy waste material that can be very dangerous to the environment. It can be added to original asphalt binder to enhance some rheological and mechanical properties of the asphalt binder. The ... -
Molecular-Dynamics Simulation Approach to Identifying PAH Release from Asphalt Concrete Pavements due to Mechanical and Environmental Factors
(American Society of Civil Engineers, 2019)Asphalt is a primary source of polycyclic aromatic hydrocarbons (PAHs) in urban runoff originating mainly from asphalt concrete (AC) pavements and parking lots. High levels of PAHs have been reported in soil and water ... -
Practical Issues in Implementation of Mechanistic Empirical Design for Concrete Pavements
(American Society of Civil Engineers, 2019)This study was undertaken to locally calibrate and implement the models for a mechanistic-empirical design guide (MEPDG) for jointed plain concrete pavement (JPCP) sections. Twenty-two newly constructed JPCP projects were ... -
Effect of Foaming Water on Rheological and Microscopic Properties of Foamed Warm-Mix Asphalt Binders
(American Society of Civil Engineers, 2019)Foamed warm-mix asphalt (WMA) produced by water injection has been gradually accepted and used. However, several key concerns should be answered such as whether the water exists in asphalt after foaming and how it will ... -
Estimation of Norwegian Asphalt Surfacing Lifetimes Using Survival Analysis Coupled with Road Spatial Data
(American Society of Civil Engineers, 2019)Combinations of different factors and their relative importance have a mixed effect on the longevity of pavements, which are essential to be understood to enhance long-term maintenance planning. This study used spatial ... -
Impact of Joint Spacing on Bonded Concrete Overlay of Existing Asphalt Pavement in the AASHTOWare Pavement ME Design Software
(American Society of Civil Engineers, 2019)This paper describes the impact of joint spacing or panel size on the performance and relative cost of short jointed bonded concrete overlay of asphalt (SJPCP) pavement using the AASHTO Pavement ME Design procedure. Joint ... -
Evaluation of Polishing Behavior of Fine Aggregates Using an Accelerated Polishing Machine with Real Tires
(American Society of Civil Engineers, 2019)The long-term durability of both coarse and fine aggregate significantly affects the mechanical performance of asphalt pavements. Extensive investigations of aggregate durability have been conducted on coarse aggregate in ... -
Methodology for Mechanistic Design of Pervious Concrete Pavements
(American Society of Civil Engineers, 2019)Pervious concrete pavements (PCP) are used as pavement structures that serve as stormwater drainage systems. However, as opposed to the hydrological design, structural evaluation and layer thickness design of PCP are ... -
Gradient Boosted Models for Enhancing Fatigue Cracking Prediction in Mechanistic-Empirical Pavement Design Guide
(American Society of Civil Engineers, 2019)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, ... -
Preliminary Local Calibration of Performance Prediction Models in AASHTOWare Pavement ME Design for Flexible Pavement Rehabilitation in Oregon
(American Society of Civil Engineers, 2019)The Oregon Department of Transportation (ODOT) is in the process of implementing the AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) for new pavement sections. However, the vast majority of pavement work conducted ... -
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 ... -
Development of Tree-Based Algorithm for Prediction of Field Performance of Asphalt Concrete Overlays
(American Society of Civil Engineers, 2019)In Louisiana and many other states, the design pavement service life (PSL) for structural asphalt concrete (AC) overlays is typically assumed to be 20 years. However, research studies showed that the actual pavement ... -
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 ... -
Determination of IRI Limits and Thresholds for Flexible Pavements
(American Society of Civil Engineers, 2019)The International Roughness Index (IRI) is an important pavement roughness measure that can be used to trigger appropriate maintenance treatments, approve new and rehabilitated roadways, and determine contractors’ performance ... -
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 ... -
