Mechanical Properties of Porous Asphalt Pavement Materials with Warm Mix Asphalt and RAP
(American Society of Civil Engineers, 2012)The objectives of this paper are (1) to characterize the mechanical properties of porous asphalt pavement mixtures containing reclaimed asphalt pavement (RAP) and a WMA additive (Advera® WMA) using Superpave™ gyratory ... -
Enhanced Evaluation of Heavy Vehicle Lane Restriction Strategies in Microscopic Traffic Simulation
(American Society of Civil Engineers, 2012)Heavy vehicles can considerably affect traffic flow particularly during heavy-traffic conditions. Large numbers of heavy-vehicle lane-changing maneuvers can contribute to increase the number of traffic accidents and hence ... -
Evaluation of Laboratory, Construction, and Performance Variability by Bootstrapping and Monte Carlo Methods for Rutting Performance Prediction of Heavy Vehicle Simulator Test Sections
(American Society of Civil Engineers, 2011)This paper demonstrates an innovative reliability analysis approach for prediction of asphalt rutting performance. In this approach, reliability was evaluated by considering the variability in laboratory test results, layer ... -
Comprehensive Evaluation of Virginia Department of Transportation’s Experience with its First Performance-Based Road-Maintenance Contract
(American Society of Civil Engineers, 2011)The Virginia Department of Transportation’s (VDOT) first performance-based road-maintenance contract was concluded in July 2007. This contract required the contractor to maintain all assets and carry out incident management ... -
Optimization Models for the Location of Motorway Interchanges: Concessionaires’ Perspective
(American Society of Civil Engineers, 2011)The location of motorway interchanges strongly affects the traffic motorways can capture and therefore the revenues for the concessionaires. This paper presents a set of optimization models aimed at assisting toll-motorway ... -
Integer Programming to Optimize Tamping in Railway Tracks as Preventive Maintenance
(American Society of Civil Engineers, 2012)In the area with railway engineering, scheduling preventive maintenance actions is an important issue for engineers and railway administrations because the optimization of maintenance actions at a preventive level allows ... -
Investigation of Thin Pavements Rutting Based on Accelerated Pavement Testing and Repeated Loading Triaxial Tests
(American Society of Civil Engineers, 2012)This paper discusses the permanent deformation behavior of unbound aggregates used in accelerated pavement test (APT) sections. A traffic simulator loaded two test pavements consisting of surface treatment, dense crushed ... -
Estimation of Design Lengths of Left-Turn Lanes
(American Society of Civil Engineers, 2012)This study is to evaluate the simulation-based and analytical-based methods for determining the left-turn lane queue storage length and deceleration length. Four traffic models were selected to estimate left-turn queue ... -
Comparison of Longitudinal Unevenness of Old and Repaired Highway Lanes
(American Society of Civil Engineers, 2012)Remixing of the wearing course in the high-speed lane of a freeway resulted in a new road surface that, compared with the old surface in the adjacent low-speed lane, was perceived as a bumpy ride by road users, as well as ... -
Structural Response of Pervious Concrete Pavement Systems Using Falling Weight Deflectometer Testing and Analysis
(American Society of Civil Engineers, 2011)Although pervious concrete material properties, mix design, and storm water applications are well documented in the literature, the structural behavior of pervious concrete pavement systems has not been investigated. A ... -
Linear Mixed-Effects Models for Paint Pavement-Marking Retroreflectivity Data
(American Society of Civil Engineers, 2011)The objective of this paper is to present an improved paint pavement-marking retroreflectivity degradation model. Previous degradation-modeling methods were reviewed and studied. The paint-marking retroreflectivity data ... -
Optimal Measurement Interval for Pedestrian Traffic Flow Modeling
(American Society of Civil Engineers, 2011)Measurement interval is crucial in obtaining stable traffic flow parameters, such as traffic flow rate, density, and speed. Credible relationships among these parameters and reasonable capacity for analysis are also dependent ... -
Design of Track Alignment Using Building Information Modeling
(American Society of Civil Engineers, 2011)In recent decades, the spreadsheet and computer-aided mapping are the major tools for track alignment design. These traditional methods can meet the design criteria, but when the design factors and the change order must ... -
Modeling the Relationship between Geometric Design and Weaving Section Flow Process of Conventional Roundabouts
