Impact of Overweight Traffic from Shale Gas Development on Pavement Damage Costs: Case Study in Louisiana
(ASCE, 3/1/2020 1)During recent years, the rapid growth of shale gas exploration nationwide has resulted in a large number of overweight truck trips on roadways in areas with shale gas development. The Louisiana Department of Transportation ... -
Modeling Cost Impacts and Adaptation of Freeze–Thaw Climate Change on a Porous Asphalt Road Network
(ASCE, 2020)Changes in weather patterns pose a threat to the serviceability and long-term performance of roads, and porous asphalt (PA) roads are particularly sensitive to the freezing-thawing (FT) phenomenon. The main objective of ... -
Study of the Factors Affecting Road Roughness Measurement Using Smartphones
(ASCE, 2020)The measurement of road roughness is important for the management of economic road maintenance. Not only is it an indicator of road condition and ride quality, but it also is used to determine road use costs, including ... -
Quantitative Assessment of Alkali-Activated Materials: Environmental Impact and Property Assessments
(ASCE, 2020)This study compares greenhouse gas (GHG) emissions, embodied energy, and air pollutant emissions of alkali-activated mortars and conventional portland cement (PC)-based mortars. Alkali-activated materials (AAMs) do not ... -
Automated Anomaly Detection and Localization in Sewer Inspection Videos Using Proportional Data Modeling and Deep Learning–Based Text Recognition
(ASCE, 2020)In recent decades, closed circuit television (CCTV) has been the most used tool for visually inspecting the internal condition of pipelines. However, CCTV inspection requires long videos to be observed and analyzed by ... -
Real-Time Seismic Damage Assessment of Various Bridge Types Using a Nonlinear Three-Stage Least Squares Approach
(ASCE, 2020)In the event of a strong earthquake, the motorway administrator will likely have to interrupt network operations to inspect potentially damaged bridges. Although continuing operation without inspection may be dangerous for ... -
Electricity System Assessment and Adaptation to Rising Temperatures in a Changing Climate Using Washington Metro Area as a Case Study
(ASCE, 2020)Increasing temperatures due to global climate change and the urban heat island effect pose a rising threat to the reliability and security of energy systems. To support climate preparedness and resilience planning for the ... -
Evaluating the Impact of Infrastructure Interdependencies on the Emergency Services Sector and Critical Support Functions Using an Expert Opinion Survey
