Evaluation of Warranty and Nonwarranty Pavement Performance Using Survival Analysis
Publisher: ASCE
Abstract: Pavement warranties are an innovative contracting procedure to protect investment in pavement construction and maintenance. The Mississippi Department of Transportation (MDOT) has managed its pavement warranty program since ...
Mechanical Characteristics of Stabilized Clay under the Influence of both Acidic and Alkalic Additives
Publisher: American Society of Civil Engineers
Abstract: To study the influence of the coexistence condition of acidic and alkalic additives on the mechanical performance of stabilized clay based on the processes for obtaining the basic physical parameters of soil and analyzing ...
Measuring In-Building Spatial-Temporal Human Distribution through Monocular Image Data Considering Deep Learning–Based Image Depth Estimation
Publisher: ASCE
Abstract: This research estimated the spatial-temporal distribution of humans in buildings through image sensing. Inputs were the in-building network, image sequences recording the movement of human, and camera parameters. Object ...
Improving Data Quality of Automated Pavement Condition Data Collection: Summary of State of the Practices of Transportation Agencies and Views of Professionals
Publisher: ASCE
Abstract: Automated or semi-automated pavement condition data collection is replacing manual data collection in many state and local highway agencies due to its advantages of reducing labor, time, and cost. However, the practical ...
Experimental and Theoretical Studies on the Shear Resistance of Steel–Concrete–Steel Composite Structures with Bidirectional Steel Webs
Publisher: American Society of Civil Engineers
Abstract: The steel–concrete–steel (SCS) sandwich composite structures with orthogonal longitudinal and transverse (bidirectional) steel webs exhibit superiorities in strength, ductility, impact resistance, blast resistance, and ...
Research on the Critical Stable Area of Air Cushion Surge Chambers in Hydropower Stations
Publisher: American Society of Civil Engineers
Abstract: The Svee formula plays a crucial role in assessing the stability of hydropower systems with an air cushion surge chamber (ACSC). This formula is derived from the Thoma formula, a stability criterion for the common open-surge ...
