Analytical Approach to Predict Temperature Profile in a Multilayered Pavement System Based on Measured Surface Temperature Data
(American Society of Civil Engineers, 2012)This paper presents an algorithm to predict one-dimensional (1D) temperature profiles in a multilayered pavement system on the basis of measured surface temperature data. The model inputs are pavement layer thicknesses, ... -
Differentiating between Left-Turn Gap and Lag Acceptance at Unsignalized Intersections as a Function of the Site Characteristics
(American Society of Civil Engineers, 2012)Left-turn gap acceptance at an unsignalized intersection is dependent on many factors. The Highway Capacity Manual (HCM) uses a single value of critical gap for all types of intersections; however, this may be oversimplistic ... -
Mechanistic-Empirical and Life-Cycle Cost Analysis for Optimizing Flexible Pavement Maintenance and Rehabilitation
(American Society of Civil Engineers, 2012)In this study, an attempt was made to evaluate and select an optimal Maintenance and Rehabilitation (M&R) strategy for a designed flexible pavement by integrating Life-Cycle Cost Analysis (LCCA) and California Mechanisti ... -
Assessment of the Effect of Pavement Macrotexture on Interstate Crashes
(American Society of Civil Engineers, 2012)An assessment and comparison of the effect of pavement macrotexture on crashes along Interstate corridors with tinned concrete and asphalt pavement is presented in this manuscript. Data obtained for I-40 in Durham County, ... -
Alternative Methodology for Determining Gap Acceptance for Two-Way Stop-Controlled Intersections
(American Society of Civil Engineers, 2012)Vehicles approaching a two-way, stop-controlled intersection from the minor roadway will wait for a large enough gap in the traffic on the major roadway before entering the intersection. The primary method for modeling ... -
Paint Pavement Marking Performance Prediction Model
(American Society of Civil Engineers, 2012)The purpose of this research effort was to develop a new performance prediction model for paint pavement markings that includes the effect of snow removal operations. The paper first develops a model based on data from ... -
Convoy Movement: Consideration of Turning Geometrics for Selected Vehicle Shapes
(American Society of Civil Engineers, 2012)This research is aimed at facilitating the understanding of the restrictions of convoy movement with object shapes as they might apply to ground vehicles maneuvering in a theater-of-operations. Such a theater would include ... -
Determining Highway Corridors
(American Society of Civil Engineers, 2012)In the highway development process, the first planning stage is that of selecting a corridor along which the highway is to pass. Highway corridor selection represents a multicriteria decision process in which a variety of ... -
Critical Assessment of Detecting Asphalt Pavement Cracks under Different Lighting and Low Intensity Contrast Conditions Using Emerging 3D Laser Technology
(American Society of Civil Engineers, 2012)After decades of research and development, a fully automated system for pavement crack detection with an intensity-based two-dimensional (2D) imaging data acquisition system under different lighting and low intensity ... -
Evaluation of Continuous Deflection Testing Using the Rolling Wheel Deflectometer in Louisiana
(American Society of Civil Engineers, 2012)The Rolling Wheel Deflectometer (RWD) offers the benefit to measure pavement deflection without causing any traffic interruption or compromising safety along the tested road segments. This paper presents a detailed field ... -
Detecting Flushing of Thin-Sprayed Seal Pavements Using Pavement Management Data
(American Society of Civil Engineers, 2012)Flushing is a pavement surface defect that affects the structural integrity of thin-sprayed seal (chip seal) surfacings. Analysis was carried out on pavement performance data to determine the combination of factors that ... -
Structural Characterization of Iowa’s Rubblized PCC Pavements
(American Society of Civil Engineers, 2012)Rubblization is considered one of the sustainable surface preparation techniques before placing a hot mix asphalt (HMA) overlay that involves breaking the concrete pavement into pieces. The design of the structural overlay ... -
Development of Pervious Concrete Pavement Performance Models Using Expert Opinions
(American Society of Civil Engineers, 2012)Pervious concrete pavement (PCP) is of significant importance in the field of stormwater management in terms of reducing runoff volume. Stormwater managers should initially ensure that PCP adequately performs over time to ... -
Unified Approach for Uncertainty Analysis Using the AASHTO Mechanistic-Empirical Pavement Design Guide
(American Society of Civil Engineers, 2012)This paper addresses the problem of uncertainty management for the Mechanistic-Empirical Pavement Design Guide (MEPDG). Specifically, development of an all-inclusive approach to uncertainty management in which model ... -
Fuzzy Logic–Based Mapping Algorithm for Improving Animal-Vehicle Collision Data
(American Society of Civil Engineers, 2012)Animal-vehicle collisions (AVCs) cause hundreds of human and wildlife animal fatalities and tens of thousands of human and wildlife animal injuries in North America. It is estimated that AVCs cause more than $1 billion in ... -
Two-Way Bandwidth Maximization Model with Proration Impact Factor for Unbalanced Bandwidth Demands
