Method for Assessment of Modeling Quality for Asphalt Dielectric Constant to Density Calibration
(ASCE, 9/1/2020 1)Traditional measures of asphalt compaction rely primarily on random cores that only measure a small fraction of the pavement. Recently, the use of ground penetrating radar was indicated to be usable as a nondestructive ... -
Field Calibration of Shrinkage Crack Width Model for CRCP in Tropical Climate
(ASCE, 9/1/2020 1)Crack width (CW) is one of the most important parameters to be considered in performance evaluation and prediction for continuously reinforced concrete pavements (CRCP) because it affects the load transfer efficiency across ... -
Assessment of Short-Term Improvement Effectiveness of Preventive Maintenance Treatments on Pavement Performance Using LTPP Data
(ASCE, 9/1/2020 1)This study aims to evaluate the short-term effectiveness of four preventive maintenance treatments (thin overlay, slurry seal, chip seal, and crack seal) on five typical pavement performances (roughness, rutting, transverse ... -
Noncontact Ultrasonic and Computer Vision Assessment for Sawcut Initiation Time
(ASCE, 9/1/2020 1)Sawcut timing of contraction joints in concrete pavements is affected by interactions between the time-dependent concrete properties, notch depth, base friction, climate, and type of saw. Even with an understanding of these ... -
Evaluation of Precut Technique to Control Thermal Cracking in Alaskan Asphalt Concrete Pavements
(ASCE, 9/1/2020 1)Thermal cracking is one of the most prevalent pavement distresses found in Alaska and cold areas of other northern states. Previous studies indicated that precutting of thermal cracks in asphalt concrete (AC) pavements has ... -
Application of Vehicle-Based Sensing Technology in Monitoring Vibration Response of Pavement Conditions
(ASCE, 9/1/2020 1)The technique of using vibration sensors to monitor the pavement roughness has been expanding in pavement engineering. In addition to the currently used automated pavement sensing method and smartphone sensing method, the ... -
Benchmarking Falling Weight Deflectometer Deflection Bowl Parameters: Case Study for Indian Conditions and the Applications to Rehabilitation Design
(ASCE, 9/1/2020 1)The paper presents the application of falling weight deflectometer (FWD) for the assessment of the structural capacity of a network of roads at district level by mechanistic-empirical technique and bench-marking of deflection ... -
Roughness Optimization of Road Networks: An Option for Carbon Emission Reduction by 2030
(ASCE, 12/1/2020 )The Paris climate agreement requires all nations to reduce greenhouse gas (GHG) emissions. Accordingly, countries have made ambitious targets to be achieved by 2030. Road transport as a major GHG contributor has been ... -
Project-Level Sustainable Asphalt Roadway Treatment Selection Framework Featuring a Flowchart and Analytic Network Process
(ASCE, 9/1/2020 1)Sustainable development is one of the most widely studied contemporary issues in the transportation sector. However, few of the existing project-level, sustainability-oriented decision tools account for complex interdependencies ... -
Improving Chip Seal Construction Using Laser Intensity Data
(ASCE, 9/1/2020 1)Chip seal is a common pavement preservation technique used to extend pavement life and improve its functional performance thoughout the United States. The need to improve chip seal design and construction is an active area ... -
Vibration Dose Value in Passenger Car and Road Roughness
(ASCE, 12/1/2020 )This study analyzed measured vibration dose value (VDV) in passenger cars as a function of longitudinal road roughness. The VDV was estimated on the passenger seat based on acceleration measured in three orthogonal axes ... -
Evaluating Cost Effectiveness and Optimal Timing of Pavement Preventive-Maintenance Treatments in Wet-Freeze Climates
(ASCE, 9/1/2020 1)Preventive-maintenance treatments help preserve pavements and delay deterioration caused by traffic loads and environmental conditions. However, guidance is needed to ensure cost effectiveness of treatments, the benefit-to-cost ... -
Flexible Pavement Response Analysis under Dynamic Loading at Different Vehicle Speeds and Pavement Surface Roughness Conditions
(ASCE, 9/1/2020 1)Pavement responses are affected by the magnitude and frequency of dynamic loads generated by vehicles, which are significantly dependent on axle configuration, pavement surface roughness, and vehicle speed. This paper ... -
Determination of Performance Jumps for Treatments of Asphalt Pavements in North Carolina’s Pavement Management System
(ASCE, 9/1/2020 1)This research was conducted to determine pavement performance jumps after treatment, which are defined as the difference between pretreatment and post-treatment Pavement Condition Rating (PCR) values of asphalt pavements. ... -
Impact of Chemical Composition on Foaming Characteristics of Asphalt Binder
(ASCE, 9/1/2020 1)During the foamed bitumen production process, cold water is injected into hot bitumen within a closed chamber. Due to mixing of these fluids and transfer of heat energy, steam is generated. The dispersion of steam within ... -
