Evaluation of Light Reflectiveness of Modern Pavement: Standard Tungsten Incandescent and LED
(ASCE, 2020)The objective of this research was to evaluate the reflectiveness of the two most commonly used modern pavement systems in the United States (concrete and asphalt). The R table used for roadway lighting design were established ... -
Fatigue Characteristics of Cement-Stabilized Granular Lateritic Soils
(ASCE, 2020)Granular lateritic soils (GLS) are available in many parts of the world as a marginal material, which can be stabilized and used as cemented subbase/base layers in pavements. Fatigue characteristics of any bound road ... -
Local Recalibration of JPCP Performance Models and Pavement-ME Implementation Challenges in Michigan
(ASCE, 2020)The AASHTOWare Pavement Mechanistic-Empirical (ME) Design version 2.0 performance models were locally calibrated in 2014. Subsequently, the software was updated to versions 2.2 (2015) and 2.3 (2016) since the last calibration ... -
Evaluation of Terminal Blend GTR Mixes with RAP
(ASCE, 2020)This paper summarizes the results of a research study that involved the construction of four test sections as part of a pavement-resurfacing project to examine the performance of different ground tire rubber (GTR)–modified ... -
IRI Threshold Values Based on Riding Comfort
(ASCE, 2020)Road surface roughness is an important indicator for evaluating the service quality and performance of asphalt pavements; the traditional evaluation index for this indicator is the international roughness index (IRI). In ... -
Case Study of a Composite Layer with Large-Stone Asphalt Mixture for Heavy-Traffic Highways
(ASCE, 2020)The large-stone asphalt mixture is a promising approach to improve rutting resistance of roads under very heavy traffic. This paper describes the rehabilitation of two test sections in Brazil using a composite of dense ... -
Technical, Economic, and Environmental Investigation of the Effects of Rubber Powder Additive on Asphalt Mixtures
(ASCE, 2020)The use of additive in asphalt mixture is one of the appropriate solutions to technically modify the properties of asphalt concrete. An additive is able to strengthen asphalt mix by modifying its technical features. On the ... -
Effects of Fines Content on Hydraulic and Mechanical Performance of Unbound Granular Base Aggregates
(ASCE, 2020)The fines content of a granular aggregate base (GAB) material (<0.074 mm) is highly variable and often related to the crushing process, transportation, and stockpiling in a quarry or site. The influence of fines content ... -
Dynamic Train–Track Interactions and Stress Distribution Patterns in Ballasted Track Layers
(ASCE, 2020)This paper focuses on developing train–track dynamic interaction models by consideration of ballast and subballast layers’ stress distribution patterns. In this paper, the existing railway track pyramid models are more ... -
Cost Effectiveness and Optimal Timing of Crack Sealing in Asphalt Concrete Overlays
(American Society of Civil Engineers, 2019)Crack sealing of asphalt concrete (AC) overlays is an important component of pavement preventive maintenance. The objectives of this study were to evaluate the cost effectiveness (CE) of crack sealing applied on AC overlays ... -
Suitable Tests and Machine Learning Approach to Predict Moisture Susceptibility of Hot-Mix Asphalt
(American Society of Civil Engineers, 2019)The objectives of this study were to determine a suitable set of tests to use with a moisture-conditioning process and to develop a machine learning model to predict the moisture susceptibility of hot mix asphalt. ... -
Design and Performance of Mixes for Use as Ultrathin Overlay
(American Society of Civil Engineers, 2019)Friction loss is one of the most critical issues faced by agencies responsible for maintaining and preserving pavement structures. Various methods are used for surface treatments, including seal coats, slurry seals, and ... -
Risk Analysis of Permeable Layer in Pavement Subsurface Drainage System
(American Society of Civil Engineers, 2019)The paper presents a framework to predict and consider the risks associated with the permeable layer in a pavement subsurface drainage system and suggests strategies to reduce the risks and improve the performance of the ... -
Probabilistic Viscoelastic Continuum Damage Analysis of Fatigue Life of Warm-Mix Asphalt
(American Society of Civil Engineers, 2019)Fatigue damage is one of the major distress modes that have a critical impact on the performance and serviceability of asphalt pavements. High variability in testing results poses a challenge for predicting the fatigue ... -
Effect of Construction Methodology on Uncertainty in Asphalt Concrete Mastercurves
(American Society of Civil Engineers, 2019)Viscoelastic properties [i.e., creep compliance D(t) and relaxation modulus E(t)] are significant input parameters in constitutive modeling of asphalt concrete (AC). Because application of input and recording the ... -
Accuracy of MEPDG Dynamic Modulus Predictions for Short-Term and Long-Term Aged Asphalt Mixtures
